i double up on my ears and try to shoot outdoor ranges haha. i just didnt know if since technically there is less area for the gas to escape vs a big single port (like my erbus barrel) and if it required kind of a hybrid approach
With that holie-joe set up it's hard to say. My steel load that I run because factory won't cock the hammer is 5.8gr of AutoComp and it is enough to keep my Open Gun flat, that is 124gr 1.165. 7.0gr of AutoComp w/124 puts you at Major PF, but you don't need that unless you are shooting open in a mjor match. You can probably shoot mouse fart loads but you won't get the effect of the ports. With 115gr RN I run @6.3 gr of Auto comp. Silhouette is my goto for MajorPf because it is like cheating, 7.3 gr w/124 and 8 gr w/115. Just back down from there till it tickles your bic. If you have AA7 you can stuff in 10gr with a 124gr. Never tried 115gr with AA7 as the case is full with a 124. I have seen similar guns run in Open class at matches and do well, and my friend that has one used 3n38, the flame throwing powder.

You should be shopping for better hearing protection! But to your question, most ammo 115gr ammo is loaded with more powder so possibly more gas. Slower powders produce more gas, and you can put more powder behind a 115gr than a 124gr. You could try a hot load with 5.8gr of AutoComp with a 124gr JHP with an OAL between 1.145-1.165 depending on your chamber this puts you in +p+ territory @145-150pf.

Nice looking old gun. It was probably converted from 38 Super. Looking at the comp, that is definately old school. Old school comps like a butt ton of gas, lol. Silhouette is my favorite for 9 maj, 7.3gr w/124/5 gr JHP Zero, Preicsion Delta etc, loaded 1.165. AA7 puts out lots of gas, but loading 10gr in a 9 mm case is just a little not fun, and you really can't control the OAL as it will grow after it drops into the tray. With your comp I would try 115gr bullets with a little more powder and see if you like it more than the 124s. Silhouette is reverse temp sensative with that in mind the load I gave is for summer and makes about 172 at 100 degrees, and at 40 degrees you will win the crono stage at 189. AutoComp and N350 won't produce enough gas IMHO, I didn't like 3n37 either. You can't call yourself an open shooter until you try 5 different powders.
When loading 9 maj, my best advice for brass is shoot it once and let it go. I tried the load 3 times, and what changed my mind was all the spent primers in the corn!

Most of these replies have never gotten close to Zen. Once you expierence Zen on a stage then you know what it is. It is like an out of body experience, everything is like on autopilot and you don't even notice the sound of the gun or the recoil. Been there done that, but when you lose it, it is a hard road back. I took 7 years off and lost it, now I don't shoot enought to get it back. With Zen 10 seconds, without Zen 16 seconds.

Shot Two USPSA Nationals and a Couple Texas State Limited Championships, and many a local matches with Ted . He had a few idioms one that I like to use from time to time is "There is nothing worse than a slow miss." He got me hooked on the shooting sport, and I paid him back by getting him hooked up with an Open Gun. I had an Infinity Limited gun Ted bought from me, and a few years later I bought it back, now that Ted is gone, that gun is more special than ever. Next time I go out to an AASA match I'll shoot it as a tribute.

Very very very hard to strike on the pistol primers. Got for my open gun and after realizing that I have to change hammer and hammer spring, sold to my friend who actually reloads 5.56
You need to get the extended firing pin. All of my STI open guns set off Mag Tech Small Rifle primers and they are the hardest of the lot. Yes those triggers break at 1.75. My CZ on the other hand won't even put a dent in them, nor will my tupper ware open gun (Glock).

I bought 3,000 124 grained Round nose plated bullets Off of Gun broker Using 3.6 gr. of clays. I think I get a better group with my shotgun. I couldn't get them to shoot for s#!t
I tried clays with several different bullets, none of them were accurate. Try N320 but don't blame me if you fall in love with it.

Hello: Nope. It burns the powder if you use faster powder like Tite Group but you still will get some soot on the brass and around the bolt etc. It is just what happens with blowback rifles. I just wipe it down with a rag along with the magazines. My Magpul Glock mags which have orange followers now look black. A quick wash in the sink with Simple Green and they look new. Thanks, Eric
I haven't noticed much powder residue shooting N320, but I will pay more attention to the mags.

Factory ammo cost it getting very close to being cheaper than reloading, primers at 10 cents is crazy. I haven't kept up with the price of Golf but I think shooting may still be the less expensive hobby, and IMHO more fun.

I use to think no Glock Open gun would run, then I got beat by one at the AASA Nationals, in the 9th round of the Man on Man Shoot Off. I still got the second place trophy and an XD. Before the MonM there was 300 rds of steel stages, I won that part of the match, the Glock was first loser.
I bought one of the darn Glock things, here on the Forum, the guy said it ran, he didn't lie! It runs like a champ. No it will not run Minor, it will run super minor which is 5.6 to 5.8 Gr of AutoComp with either a 115 or 124gr RN or JHP, Over the crono this comes out to about 145 pf. For Sminor I use an 11# spring, mags have the Taylor Free Lance extension and hold 27.
For Major, well it is a hand full but at 172 pf (7.3gr of Silhouette) with a 124gr JHP (Precision Delta), it runs the big sticks no problem. The recoil spring is a 22#. The gun is all LoneWolf with an SJC comp.
I've run about 20-30k rounds thru it with no memory of a single FTF or not going bang. It runs all pistol primers, however don't try a MagTech rifle primer.
If I didn't have 3 STI platform open guns I'd shoot the Glock all the time. I take it out for Steel Challenge and 2 Guns.
Maybe because I don't have a 5# fishing weight on the front?

L10 appears to be the odd duck. I'd let it go and keep SS just as it is.

Back Ground - 9 major SVI 140 mag with Dawson 2+ pad, has worked for years without issue. I'm having issues on occasion when a round gets under the follower and the mag goes salt shacker. I alread replaced the spring and the follower and the problem persists. Mag is clean and has not been dropped after loading.
The twin to this mag (zakley the same) continues to work 100%, as does the longer brother 170 mag.
Spring and follower are grams.
Ideas?
-
I've used 140's without spacers, but 170's are a different story. I use the metal spacers, grams guts. New mag springs every year, buy the 10 pack of 170 springs and cut them for the 140's. Keeping them clean and NO LUBE works best, although for a time I used a drylube spray with success, then ran out and never started again. A 100% means shooting a whole season without a malfunction, not one match.
-
imho the old SVI mags are the best for 9 Major with no spacer. Plain ole STI Mags work good for 38/38SC. I always look for them when I drop in.

Just my opinion so take it for what it’s worth. The difference will be noticeable but not remarkable. I didn’t like the sluggishness of 147’s and switched back to 124’s. When I did that I started reading that many many shooters thought the same. Much more accomplished than I will ever be as well.
IMHO my favorite bullet for 9 mm minor is 135gr Bayou, propelled by an IMR7625 or N320. I agree the 147gr is sluggish and the impulse thud reaks havoc on my timing, it is all in my head, perception.

No load is going to make you fast as rimfire. My load for Steel Challenge with a 2011 Open gun is 5.8 gr of AutoComp with a 124gr JHP, (1.165 oal) this load ties the holes together at 25 yards. Since the pandodemic has made getting what you want hard, I have been running Armscor 115gr RN bullets at 6.0gr and they are not as accurate but still plenty accurate for steel challenge. There is enough gas that the gun handles a lot like you are shooting major, the impulse you are use to is there, and the gun runs. These load crono out @145 pf.
When I've tried those mouse fart loads you know the 95gr with a fast powder like N320, Tite Group, WST etc, it was like I was always waiting on the slide to close.
For the non open gun I do run pretty much standard minor loads 125gr coated with 3.8gr N320. I don't worry much about how fast I can make up a shot, I concentrate on hitting it the first time. I just ride the recoil to the next target.

For simplicity, just a Volquartsen sear and Tandemkross hammer bushing, about $50 in parts and it will make an absolute world of difference.
Polishing the button track of the mag inside and out does wonders. Keep the mags clean, no lube of any kind. (this means clean them every time they are used!). The gun also needs to be cleaned and lubed after every match. I put the whole VQ parts kit they call it the Competition kit. The extractor and firing pin are a must have.

IMHO Lee Dies are crap, had them sold them. Once fired is fine for Maj loading I've shot a few 100,000+, loaded on Dillon 650 with Dillon dies, or Hornady with Hornady dies. I started out shooting them more than once, but when I saw all the primers in the corn, I made the decision once and done, replacing slides is expensive (breach face erosion). One step I added to the process is the magnet check, since some brass isn't brass but looks like it. I started out running all the brass thru the casepro (rolling), but changed to only rolling the drop check failures.
The drop check is your friend, if it doesn't drop all the way in and fall out freely it is bad, toss it or fix it. I also recommend the bullet cases, makes it easy to find that short round or a high primer. For major matches I will do a second drop check, insurance.

I started out shooting Limited with a TS, there were two problems, 1- Not enough head space, you have to load short, I was shooting titegroup and 200gr JHP's. 2- Switched to Precision 185's, didn't blow up cases but the molly coating clogged the barrel. Sold it bought a used taxi tested tuff STI Edge, no problems. Upgraded that one to a Dawson HPF edge even better. Bought an Infinity, it is a good safe queen, the Edge edged it out.

At the very least, I'm competing against the classification system, the same way the one Open guy at a 20-man club in the middle of nowhere is.
Why? What is a division that only attracts 1% of shooters harming? How does it improve the game to remove it?
Not everyone goes to the match thinking they are going to win the Hummer. I don't go to a match thinking who can I beat today. I'm more into my hit factor than how I finish. At 73 I know that I'm probably not going to out run a 20 something, I shoot because it is fun. I shoot Open, because I like it, but if the mood strikes it could be Limited, SS, CO, or PCC. Before CO and PCC came along everyone aspired to shoot open.

Ah, a beginner eh??Thanks, I think I will probably count out the amount I “think” is around 300 cases just to see how many it really is. The Dillon manual says to fill it up to halfway. I only put in half that much at most.
Once you get the screws tightened up you can move on to solving the infamous brass rain! Or maybe even the once in a thousand upside down case. Both of these appear to be related to the "Case Count", if too few cases are in the hopper it rains more often and the number of upside down cases goes up. Running on High rather than low seems to give the most reliable feeding. 9 mm is more problematic than 38 Super, that shorter case length is more prone to wedging in the funnel leading to the tube, then it rains. If you listen while loading most problems can be detected early.

@AHI So pull them back by 0.005” at a time and shoot for groups?
I shall try that with a few loads to see if I can get better results.
I’m really beginning to thinking this CZ is a dud as I borrowed a Tangflo Stock ll extreme and shot way better with factory Geco 124RN factory loads.My CZ shot ok with the same but not nearly as good. Maybe I’ve just lucked out and ended up with a s#!tty barrel.
I've never bought a new CZ, they have all been used (5), but I did buy a couple of Tanfo's new. Back to CZ, my Shadow 01, I never did get a set of sights that could be adjusted to POI to POA, close but no Cigar. Close enough to shoot production. Last year I decided to throw a DOT on it. Due to "political" factors I had new loads to test. My most accurate STI open gun is a tack driver, it connects all the holes at 25 yards with ease. Next up the 12 yr old Shadow 01, with its new dot. Ooh crap it is out shooting the STI. All shots fired from a bench rest. Then comes the real test, free style, same 25 yards, STI open nice group about 2" for 5 shots, next up the CZ, oops my FU is weak on this one, about 4". Not the gun the Indian. The steel test, like a steel challenge stage, on the timer. Not believing it but I'm faster with the CZ, the timer don't lie.
On rifle grouping is pure science and discovery just a couple tenths of a grain makes all the difference in the world. In pistol the POI can move 4" at 25 yards just changing to a different powder (major power factor 9 mm), not so much with minor. Test the gun and not the Indian, do some shooting on a bench rest. Nothing wreaks havoc on pistol accuracy like a loose barrel bushing, then barrel lock up. I had a gun that the slide was so loose on it, it rattled when you shook it, but it was still very accurate with good barrel lockup and a tight bushing. When I shoot a strange gun I'm more accurate because I take more time on each shot, the psychology factor.

I've only loaded a few 100,000 rounds, but I've never counted the cases. I keep Brass in a 3# coffee can, I pour in a half can at a time. When it starts to get low, and you can hear this, I pour in more. The amount of brass is a level that is @1 1/2 inches below the clutch. When you let the amount of brass run low you will encounter more anomalies, up side down cases, and the dreaded brass rain. I tighten the clutch as needed. When I pour in brass, I give it a shot of one shot, this keeps the reloading smooth and easy. I clean the case feed when its dirty.

I gave up a while back and just bought Precision Delta's, it was either that a convert to spud gun.
