SA Friday

I didn't read the thread, but made a few revisions of the ppt to show what I would tweak in the stage. It's a good stage, but I moved some of the targets and fault lines to work out shoot-throughs. I also moved some of the targets to get a few more engagement options. FWIW. USPSAstage1 SA Friday revision.ppt

Yes, please don't. In fact please don't play with any of the Alkali metals in pure form outside the lab. They all have violent oxidization reactions.

The mixture results in carbonic acid for a short while (from the initial acid-base reaction). That's what breaks up the clog. Then it breaks down to carbon dioxide (the gas bubbles) and water (from the secondary decomposition reaction). Then, the hot water flushes the loosened greases out of the pipe.

Some don't like the U die. I do, and use it on all of my 9mm, 40 cal , and 45 acp. It will solve your problem. Based on the numbers, I suspect you are probably just fine though. If you have to push hard enough to leave red marks on your thumb and it's uncomfortable to get the bullet to move, it's in there pretty tight.

If the swabbing can give a false positive from heart attack medications (nitro tablets, CH2NO3) and fertilizer (ammonium nitrate, NH4NO3) the machine is obviously looking for NO3 (nitrate) as it's found in both and almost all explosives used by terrorists. Nitrate is in guncotton and nitro based smokeless powders. It's NOT found in GSR. The oxygen in the nitrate is consumed in the chemical reaction. TSA is talking about finding nitrate from GSR. Spill titegroup all over your shooting bag, you might have a problem. Rub TG all over your hands and not wash them, you will have a problem.

Agreed. Something is not right. I would also check your scale for accuracy.

T-3 and T-4 are low to the ground and leaned back targets. There are two openings on the left side of the shooting area right next to the targets. We set them toward the back of the openings so they could easily be engaged without a 180 concern. T-3 looks like it's way forward, but it's the only way I could represent the general location of the target without it being blocked by the wall in front of it.

It's one of those stages you just want to shoot again when you're done because it was just too much fun. It's good times.

Haven't posted a stage in a while. We set this one up and shot it a few months back. It had a lot more options in it than I originally thought it would. It got shot at least 3 or 4 different ways in the heavier shot divisions. Cochise.doc

Man, stage 2 looks awfully familiar. I swear I've seen it before.

Are you weighing every powder charge for every round of your test ammo?

Try 3.6 to 3.9 gr with the 147gr MG bullet for the right pf zone. If it bothers you to go over the charts (which are by most's testing to be inaccurate), just use Titegroup. With a FMJ, you really can't go wrong with TG. I load around the 3.9gr of Solo 1000 with a MG 147gr CMJ at 1.125-1.13 OAL. I have found no advantage of loadling longer with a Glock 9mm, and some bullets will pinch in the mag if loaded longer. Shoot 135 pf. There is no advantage to shooting any less, but there are a lot of disadvantages; the gun doesn't run as reliable, the steel doesn't fall as well, and I've found non-adjustable aftermarket sights are not made for a POI with a lower pf.

I'll bring some of the 9mm I reloaded with a U die to the next Aurora match on 4 Apr for you to compare against if you want. It's kinda hard to tell from the photo, but I get a ring too. as long as it's not scraping or pealing off the brass at the ring, it's probably OK. Edited to add: Damn, just looked at the second and third pics. Ya, that isn't right. Send the die back.

Without comparing the OAL the comparison is moot. A round with Solo 1000 loaded to 1.2 OAL in comparison with Red Dot loaded to 1.135 OAL could very well act exactly the same. Solo 1000 throws crappy. Simple fact. Measure each powder charge in every test round and chrono over and under .2gr of your pf mark. Solo 1000 will teach you a lot about your powder throw and system. Test rounds for measure adjustment at least every 25 rounds while reloading ammo. I had problems where I went up in charge weight and the velocity didn't do anything. It was the powder throw. I went back and retested weighing every powder charge and adjusting them as needed and immediately saw quantative results.

We have a winner! PM me your address and I'll send the book. "Close": From Rubio's outside patio, I'm looking at the Skeptical Chemist's outdoor patio. Rubio's has been my traditional Dillon lunch spot for many years, ever since Arnt Mhyre took me their for my first Maui Fish Tacos. But I have a new favorite. I wonder what that might be, for book number 2. be Lol, in my family we call that the "hide the silent 'h' game". Sincerely, Sean Myhre (no relation that I know of...)

PM Cha-lee. He can probably give you some ideas or may even know the fix.

Hate to say it, bro, but I think you may have to postpone the looking tomorrow. I suspect the whole front range will be shut down. We had 8 inches on the ground here in Castle Rock at 2200.

I don't have exact data, but both should work just fine based on my experience with 200gr rounds and both powders. You will probably be looking at mid to upper 4.xgr of powder with both with a 1.25ish OAL. My old Solo chart shows 4.6 to 5.1gr with a 185gr Hornady and a min OAL of 1.15. Clays should take less as it's a touch faster burning.

If you look around in some of the old posts, there's some info about polishing the inside of the Dillon powder funnel. From what I've heard from very experienced Dillon using reloaders, this can help get a consistant powder throw with the fluffier powders.

I personally view all powders as temp sensitive. I usually see the terms temp sensitive as the rounds get hotter as the outside temp gets hotter, and reverse temp sensitive as the rounds get hotter as the outside temp gets colder. Even though I view all powders as temp sensitive or reverse temp sensitive, I also believe the various powders have different degrees of temp sensitivity. Some I have tests have fluxuated much more than others. In some of my testing, WST fluxuated in the range of 5-6 pf. Universal clays was virtually unmeasurable in 40 cal when I was using it. Results vary for everyone and every gun based on all the variables of the load, the weather conditions, and powder lots. Chrono'ing your ammo under the varying weather conditions over a year of shooting and charting out the results in a data table is the best way to see just how sensitive the powder is to temp. Doing an initial test of reloads where one set is kept at a freezing temp and another set is kept at 80-90 degrees F is a good way to get a base line of sensitivity. IMO, as long as your pf isn't fluxuating below pf requirements or above pressure allowances, and is maintaining accuracy and POI, the powder is fine. I avoid powders I have to change the load for the seasons.

How was the match advertised/named? That sounds like a shoot-off format and there is always the chance of elimination on the first round. If it was advertised as a 'match' I would feel cheated a bit too. Shoot-off's around here are typically pay-out for the top three also.

Get rid of the FCD and use a regular seating/crimp die. Switch to a U sizing die. Your set-back problem will go away.

The CO state USPSA match is on the east side of the mountains this year. When we have it on the eastern side we combine the state championship and the Mile-Hi matches. 10 stages and chrono, at Ben Lomand Gun Club outside of Ramah,CO. Match Fee is $85, $95 if received after 1 Jul 10. Sanctioned Level II match. Trophies and cash pay back to class and division winners. App is attached. GAME ON! 2010_Match_Application.doc

I would still check this. It initially sounded to me like a broken trigger spring. If so, it could have wedged the back of the trigger bar up and you got a double from it. It's easy enough to check, and if the problem, easy enough to fix.

Leading is primarily caused by issues other than the powder being used. As mentioned, the hardness of the lead bullets is important. The diameter is important too. If the bullet isn't sealing in the boar, I don't care what powder you use, you are going to get a sheering effect along the side of the bullet and depositing of lead all over in the rifling. Also, what gun and barrel are you using? Last I remember, you were shooting a Glock 34. Getting lead or moly bullets to work in polygonal rifling is a hit or miss deal at best. Some get it to work, some don't no matter what they do.
