My Marvel Unit One works well with standard velocity ammo. Even with the 12 lb. recoil spring it will not handle high velocity well, Slide action is too violent. The steel slide is fine with HV. The Unit two works fine with HV.
The Nelson 22 conversion is very finicky about mag catch height and ejector position. I had to return mine,
The Advantage Arms units work well. Personally, I'd go with the Target version. It is the equivalent of the Marvel Unit One with a much better lock back feature. It is considerably less expensive than the Marvel or Nelson.
If you can sweet talk Chet at CWA into making you one of his conversions, do it. They are superb. If you are willing to spend the money for a 2011 based 22, see Chet also. Several GMs I shoot with use them and they are 100%. Even though it has a 2011 grip, it uses 1911 10-round mags. It is the Precision Defense V3 mentioned above. I have the same upper on my 1911. It just runs and runs. Not at all ammo finicky.
If you go for the Marvel Unit and will never shoot bullseye, ask them to lengthen the leade before sending it. The Unit One is intended for precision bullseye and has a short throat. Bullseye shooters want the lands to engrave the bullet for utmost accuracy. That results in not being able to extract a chambered round without fussing with it. Having it throated cures that.
Having shot all of the above, and several I wouldn't use if you gave them to me for free, I'd go with the CWA if you can get one, or the Advantage Target if you cannot. The Advantage is difficult to find. I bought mine from Palmetto State Armory.

The next time you run into that situation, pull a bore snake through the gun several times, then put a line of lube on the top round of each mag. Water tens to make the powder gunk in the chamber sticky.
You also need to retune your extractor. Better yet, switch to a properly set up EGW HD extractor and the problem will go away.

I wore out my CWA conversion, so now I'm using my Marvel Unit One without a comp. Even with SV ammo, the timer picks up the shots.

When I bought mine I was told by CZC NOT to use the buffer. No damage to anything after lots of 40 major rounds through it.

I have used Hornady, Lee and Dillon dies for pistol. I would suggest you start out with a Dillon Square Deal B. I've loaded many thousand bullseye accurate load on that press. I agree with you on the priming system. I'd suggest you look into the Hornady Lock n Load AP press. In m y opinion, it is superior to any of the Dillons until you get to the 1050/1100 range. The shell plate advances in half steps, so there is much less chance of powder spillage when the shell plate turns. Their priming system is much better, Their powder measure puts Dillon's to shame. Super consistent throws.
When I use a sizing/decapping die it is a Hornady. It sizes brass so you get really good neck tension on the bullet when seated. If I'm using the sizing die, I put a Mr. Bulletfeeder two-step expander/funnel in the powder measure. That ensures the bullets go into the case vertically, and don't cant when the shell plate rotates. I use a Hornady seating die, but do not crimp. I crimp with a Lee Factory Carbide Crimp die. It is important to seat and crimp in different stations.
When not using the sizer, I replace it with a Redding two-step expander die and back off the Mr. Bulletfeeder funnel, so all it does is drop powder. The press operates smoothly and I get SDs in the 4 to 6 range.
I have a set of Lee 9mm dies, but I don't like them as much as the Hornady. My Dillon dies were not for 9mm, so I can't comment on them. I did use Dillon dies for 40 and 45, and prefer the Hornady dies

Well, I just gave up. Low power steel loads for the 16" are filthy dirty. I'm lucky if I can make it though a six stage event without the firing pin jamming because of all the crud that gets deposited in the channel. 168 PF is hard on the shoulder at the end of the day. So I just ordered a Taccom 16" sleeved barrel. I ordered the 15 oz. version. It shouldn't be as whippy as the Wiland I shot years ago. I don't think the extra 1/2" of barrel will add much velocity. Tim reams the chamber with a Manson reamer, so there should be no issues. Finally, I'll be down to two 9mm loads, one minor and one major. It used to be five different loads.

With a finish reamer how do you keep from going to deep?
If you are just throating, stop when the flutes hit the front chamber wall. Easy to tell when. If actually chambering, use go and no-go plugs.

The 100gr SuperVel ammo makes 137 PF in my 16.1" Leadstar barrel. It won't function in my 2011 Open gun with 6V recoil spring. My 124gr, 134 PF 9mm minor load (5" barrel) makes 168 PF in the 16.1" barrel. Both are flat shooting.
Flat shooting for USPSA requires speed. The 100gr @ 1377fps has almost no dot movement and a laser-like trajectory. Sighted at 25 yards, you are on at 50 with less than 1/4" high in between, and 1/4" low at 59. Same for the 124gr @ 1359fps. No more that 1/4" high or low between 25 and 61 yards.
My dot does not move with a 147gr @ 985fps (out of 5" barrel), No idea of the fps out of a 16.1", but it is higher. I can put 20 rounds into a 2" circle at 25 yards as fast as I can pull the trigger. Recoil in a 5.5 lb. gun is significant. Trajectory in no where near as flat as the two previous loads.
Less velocity with any of these loads means more dot movement, but softer recoil.

On a lark I chrono'd my 9mm minor ammo today. 124gr Plated over 4.4gr AA2 @ 1.135" OAL. 134 PF out of a 5" 2011, and 168 PF out of my 16" PCC barrel.
I'm not as daring as @shred so I'm not shooting my 184 PF major ammo out of my PCC. 10.8gr AA7 under a 115 JHP. It goes and average of 1600fps out of a 5" barrel. I can't imagine what that would be out of a 16" barrel.

Some thoughts: first, if you use SWMP or AA7 for 9 major, the case is not filled to the top. Nothing slings out when the shell plate turns. Second: there are TWO advantages to 38SC. One is it is a straight walled case. NICE. The other is case capacity. HUGE. You can fit any powder you want and a small fridge in there. You CAN get it to shoot soft AND flat at the same time. You can come close with 9 major, but you have to settle for one or the other, or some of each.
All of the matches I shoot are lost brass matches. Some actually are. The rest are for me, because my back will not stand up to the constant bending. So, 17 cents for 38SC to be used once and left, vs. 5.5 cents for fully processed, once fired, same HS 9mm brass also left on the ground. $1190 vs. $385 per year. The $805 delta is significant enough for me to stick with 9mm. If someone were to give me 20k 38SC brass, I rechamber one of my 9mm guns and shoot 38SC.

I wrote to PD about it but haven’t heard back. fwiw we have sot 8-10k of these same bullets previously without issues, so this appears to just be a bad batch.
Hope so. I just received 4900 115 JHP V2s. Just started to load them. So far, no gunk.

Coco, there are some strange opinions here. You are 75 and don't want to do the brass chicken dance after every match. I didn't either. That's why I went 9 major. Once you rebarrel, you will never shoot 38SC again, unless you have a little left over.
Buy a one piece barrel/comp from Brazos and have a good smith fit it to your existing slide. It will last longer than you and you'll never have to re-Loctite a comp. As far as 9mm being hard on the gun, I see no evidence of that. My major load was 10.8gr SWMP under a 115 JHP for 175 PF. I have no idea how many I've shot, but it is a lot. Just recently I ran out and substituted AA7. I had none left from last year, so I hurriedly loaded some up with 10.8gr. After two matches I'm wondering why the dot is jumping so much. I chrono's and found the 115 JHPs were going 1600fps, 184 PF. No damage to the gun at all. I'll be pulling the remainder and loading softer.
I buy fully processed, once fired, roll sixed, resized, swaged, polished same HS brass for 5.5 cents each. I generally buy 6k at a time. I was down to 5k primers and had the opportunity to buy 5k new Win+P HS brass primed with lead free primers for 14.4 cents each delivered. My SDs for 10 and 20 round strings are always less the 6. There is absolutely no reason to use mixed HS, range pickup brass for major. I'll admit I do just that for 132 PF minor and 100 PF sub-minor.
-
Yeah, HAPs are notorious for that. I used to clean them out with the equivalent of a dental pick. Later I found it did not affect accuracy, so I quit. The Zero clones of that bullet do not have the problem. Nor do Everglades or PD.

I don't buy the price argument against painting. Steel Target paint has gone up in price, but $65 per case/12 is not exorbitant. We go through an average of 3 cans per stage for a 70 gun shoot. The club I shoot most often at charges $20 for the first gun and $10 for the second. They have enough money to buy new targets, make new bays, improve the grounds, host the State match and still have enough left over to award $3000 in cash prizes at the end of the season.
BTW, if you shake it well, Steel Target paint works when it is 22 deg.
-
If you want to ream or throat nitrided barrels you need a carbide reamer. They are expensive. You can rent them. I'm told you can do it with a tool steel reamer, but it will be dull when finished.
-
Every club I shoot SCSA steel challenge at paints between EVERY shooter. None allow a two gun shooter to shoot back to back (LI). Nobody gripes. Even on squads of 5 shooters/ten guns everything gets painted and things move along.
Non-SCSA matches like falling steel, outlaw and the like rarely paint at all. Best case they paint for the next squad.

I wanted to experiment with some 115gr but the needed powder to make PF is higher then I’d like. If we had a 160pf requirement I’d definitely give them a try.
I use 115 JHPs under 10.8gr AA7 Powder at 1.161" OAL. Case is mostly full, but powder doesn't spill out when the shell plate turns.
-
I've completely given up on Aftec types. Now I use only EGW HD extractors. They run 100% and last seemingly forever. I will not that for 9mm I have them custom milled so the are 9mm specific, not 9/40.

Where are you getting your JHP?
Precision Delta.
7 hours ago, shred said:Most coated bullets these days aren't hard-cast (or not very), which is not a bad thing.
Rogers PC coated bullets are 21 Brinell. Most are between 15 and 18, still hard. Even Berry's uses 15 Brinell lead for their plated bullets.
I agree with you on the Precision coated. Slick and more accurate than most. I use them in 40 and 45. Unfortunately, they are gone and I only have 2k left.

You are going to have to experiment. A lot of gas will be shooting up from those ports. That will bleed off velocity. With too slow a powder you may drive the muzzle down. I'd start in the middle of the range using a 124 JHP over a middle load of AutoComp. See what that does to the muzzle, and what the PF is. Adjust powder charge up or down to fine tune. If you are making too much gas with AutoComp, drop down to AA2. It is a little faster. My 132 PF load is 124 JHP over 4.5gr AA2. It shoots soft and flat. I only have two poppels. You have seven. So you won't reach 132 with my load.
Before I went to a slower powder for more gas than AutoComp, I'd try 115gr JHPs.

i guess that was more along the line of what i'm really trying to figure out what are the disadvantage and advantages to coated vs plated
All coated bullets smell when fired. HiTech is the worst. Coated bullets start life as hard cast lead bullets. Diameters vary. Coating thickness varies. Some brands are infamous for leading the barrel. They are less accurate than good plated of jacketed. If you shoot them at steel they break up into larger chunks than plated or jacketed, and they fly father.
Good cast lead/coated bullets are expensive. Same with plated. The majority of the makers of really good coated and plated bullets went out of business. If you are going to be paying 9 or 10 cents each for bullets, why not use all JHPs. They don't foul comps and poppels. They don't lead your bore. They don't smoke. They don't smell. They are super accurate.
I buy JHPs in bulk for 9.5 cents each, delivered. Berry's plated on sale, or inexpensive coated are going to be between 9 and 10 cents after tax and shipping. Why bother?

i looked at JEM a while ago i didnt know they werent offering the short blocks thats good to know. im just not a huge fan of the brazos slide cuts
You can have Bob use a bald slide for the short block and make your own lightening cuts.

I've shot somewhere between 15k and 20k once fired RP cases for major with zero issues. It is very unlikely to be the RP cases.
How is the neck tension on the 115 loads? If the crimp is good, it is a primer problem. The 124s are heavier and resist initial movement longer. It is possible they stay still long enough for the flame front to develop and ignite the powder, whereas the 115s move more quickly and do not allow that. I'd be surprised if the 124 loads still made major.
