Let me preface this by saying I do not yet shoot PCC in USPSA. When I do it will be with the WilandUSA LLW barrel for no other reason than that is what I'll shoot for Steel Challenge. If I were able to, I'd go with an SBR. After watching the gyrations PCC shooters go through to clear walls and barriers, I can see the advantage. That being said, it may be just my area. Most stages are not PCC friendly, and one MD is openly hostile to them.

Here's one from Wiland. 124 poly coated bullet over 2.8gr 231. He says it shoots like a pellet gun.

I've been buying mine from Ammobrass, LLC. I buy 6000 at a time for under 4 cents each. Deprimed, decapped, primer pocket swaged, roll sized, cleaned in SS media, dried and a light coat of wax applied. I'm halfway through my second batch this year and I've had zero defective cases. 100% drop into and out of my Shockbottle checker. https://www.ammobrass.com/product-page/9mm-fully-processed-reloading-brass

I have the regular e2 grip and it doesn't move in my hands. I don't use anything on my hands to help.

My MBX 40 mags were 20 reloadable. I could put 21 in some, but I refuse to slam a mag home. I use the TTI spring, +1 and base pad with STI Gen 2 tubes. They work great. I still use my MBX 9mm mags for USPSA. They just run and run.

I PM's George Jones with the question of what rules apply. He said for SCSA the ONLY rules that apply are in the SCSA rule book. NOTHING from USPSA applies. So no finger in the trigger while moving more than one step is a DQ. I also talked to Zack Jones about the issue of creeping. I specifically asked if I had to assess a procedural if the shooter started to move before the beep and I couldn't catch it, or could I stop and restart. He said it was fine to stop the shooter and begin again. That is what I have been doing. I generally don't see many issues, but I agree following the recommended fixed cadence between Stand By and beep does encourage anticipating and creeping. I had two instances at the match last Sat. Both anticipated the beep. One was my fault because the beef was a tiny fraction of a second slower than the previous three and he jumped. So you can't win either way.

TTI has the springs, +1 follower and 4mm base pads in stock. All you need is an STI tube and you build it yourself. 21+1 reloadable in 40. 24+1 reloadable in 9mm.

I won't shoot in a downpour. Drizzle or light rain, yes. Unfortunately, Patagonia no longer makes the ultra lightweight soft jacket I use in summer. It was designed for cross country skiing or cycling, with long arms and length. No matter how far you extend your arms of bend over, nothing rides up. Here are some slightly heavier substitutes. https://www.rei.com/product/143469/patagonia-houdini-air-jacket-mens https://www.rei.com/product/111927/patagonia-airshed-pullover-jacket-mens https://www.marmot.com/mens-bantamweight-jacket-31590.html?dwvar_31590_color=001&dwvar_31590_size=00030XL&cgid=men_jackets_waterproof-and-rain#start=1 I've become addicted to materials that keep you dry. In the summer I wear lightweight, breathable tactical long pants from Columbia. They weigh ounces. For shirts it is either Arctic Cool or Mission T-shirts. Both literally remove sweat from your skin and evaporate it. Both have active cooling fabrics. Junk like Under Armour or ExOficio just glue your sweat to you. The main difference between the Artic Cool and the Mission is the AC distributes the moisture throughout the fabric while evaporating. So the cooling effect is more gentle, but overall. the mission does not distribute, so when a gentle breeze blows you feel like an ice pack was applied where the sweat was absorbed. Columbia's Freeze Zero works well also, but is heavier. Mission's Activematrix underwear wicks, is breathable and cooling. Their cooling towel is a must have, as are their arm sleeves (for me). For cooler weather nothing is more comfortable than a Patagonia Capeline silk weigh T under a Lowe Alpine Arctic Tech Level 1 fleece. Cover with a light weight shell for wind and rain. For slightly cooler temps, a mid-weight Capilene T with long sleeves under a Polar Tech long sleeved shirt it tops. Colder yet, add a Patagonia LIII pull over fleece that you can tuck in your pants. If it's below 30 I also wear a Beretta Down shooting coat, and remove it when it's my turn to shoot. At 40 degrees I wear Capilene long leg underwear. For 30 I wear polar tech 'long johns' under my pants. All of these things wick moisture away from you and either evaporate it or transfer it to the next layer for evaporation. I am never wet when hiking up Mt. Vesuvius in summer or climbing up and down mountainsides in the Dolomites and Alps. Even hiking in the Bershires where the temp is 90 and the humidity is 90%, this stuff wicks, evaporates and cools. BTW, I do like Columbia's stuff. I have a lot of it. It works. It's just not the fastest or lightest weight.

It is not pressure in the bore that works the comp, although for a given amount og gas, higher pressure is better. However, it doesn't work that way in real life. It is the volume of the gas generated that counts. For instance my major load of 7.2ge Silhouette is much higher pressure than my 10.2gr Major Pistol. The MP load shoots much flatter and softer, because it gererates more gas. The formula was from Winchester. Hodgdon uses the same formula except for using 4700Pw instead of 4000.

I also replaced GoGuns and RHTs with the Akai. They feel perfect. I also tried no rest for a while. That didn't work either, because my weak hand grip around my strong hand was not as good.

Yes. The formula for recoil is E=(Bw x Mv + 4000Pw) squared / 64.348 Gw when Bw is bullet weight, Mv is muzzle velocity, Pw is powder weight in lbs. and Gw is gun weight. You see that Mv and the other values inside the parens ar squared. So changes to any of those values has an outsided effect. For example the same load that makes 1300fps of of a 16" barrel makes 1050 out of a 5" barrel. 1050 squared is 1,102,500. 1300 squared is 1,690,000, and significant increase. Powder weight in pounds makes a little difference. Say the difference in charge weight is 0.2 grains. That is 0.0000285 pounds. Squared that is 0.000000000816. So you see it makes little difference. Chamber pressure does not 'work the comp. Gas volume does. The more gas you generate, up until some of it jets out the front, the better the comp 'works'. I want to use light loads, commercially bought if possible. So the shorter barrel is the way I want to go for two reasons. First it will swing better. Second it will give me pistol velocities out of a 5.5" barrel. The commercial 115 @ 950fps out of a 4" barrel grows to 1200fps out of a 16". A third reason is there are many bulged barrels because of trying to shoot a low PF load out of a 16" barrel. A round soesn't make it out of the barrel and the second hits it and bulges the barrel. There was a recent post here about a guy using an 11" barrel. It was cut down from a 16" because a bullet didn't make it out and the next bullet bulged it.

Is that with all coatings? I don't see the coating getting flame cut like it would in a comp.

I do the same. The ground is not always even, so my first step is out of the box with my right foot while looking at the ground. I'm moving between forward and laterally. Second step with left foot looking at target and bringing gun to bear. Third step lands me in the middle of the box ready to shoot. Usually the first shot is off before my left foot hits the ground.

Gore-Tex is too slow and Frog Togs are too heavy and don't breath well.

Look at a Patagonia Catalog. I use one of their resistant shells designed for cross country skiing, cycling, etc. They are breathable, light weight and will keep you dry in anything but a torrential downpour that last for hours. Mine fold up small enough to put in a jacket pocket. I also have a heavier Columbia OmniDry waterproof, breathable jacket with hood that I use when I can take it off to shoot. If it is raining hard I keep the Patagonia on. It doesn't interfere with movements.

I only shoot pistols so far, but I do the same. When I'm one step from the box I bring the gun up into firing position, but my finger is outside the trigger until my right foot hits the ground. I do look where I am going up until the last step, because I've seen too many stumbles.

There is a difference between aiming and pointing. While you may be pointing the gun at the right array while moving, you aren't aiming. You are watching where your feet are going. At every LII and LIII match I've shot, the MD emphasizes this at the match briefing and tells the ROs to watch out for it. 8.1.1.7 is specific. USPSA carves out an exemption to avoid a judgement call. They didn't always. SCSA does not.

That's what I'm going to do as soon as I sell the BSF barrel.

I'm going with the LLW for just the reason the OP listed. Also, it will be softer recoil. The 115 @ 950 109PF load I plan to use gains 250fps in a 16" barrel.

I more interested in transition speed for Steel Challenge. It will also help if I decide to use it for USPSA. I kind of doubt it, because I love Open so much. I need a 16+" barrel, because it is legal everywhere and I don't need a stamp.. I'm going with the WilandUSA LLW barrel. Although it weighs 15 oz., the weight is concentrated near the receiver. The barrel is 5.5", so I don't get the increased velocity (and recoil) I'd get with a 16" barrel. Since there is no comp, I can shoot less expensive coated bullets without worrying about crudding up the comp. I've tried 19 oz. pencil barrels. They swing slow. I was going to go with a BSF carbon sleeve barrel at 16 oz., but that is not much of an improvement. The Polar Moment is not as good as the LLW. There are two things that decided me on the LLW. The first was my newest Open gun. It is heavy with a SS grip. Everyone said the transitions would be slower than with my lighter poly grip guns. I set the gun up so it balances on my left index finger, so really all the weight is between my hands. I'm faster with this gun than I was with the others. Why? It doesn't feel muzzle heavy. Now my other guns feel like I'm swinging a log. The second was how much faster my transitions were with my full race, light Buckmark over the 1911 with conversion I have been shooting. So my recommendation would be one of the ultra light barrels you mentioned. I went with the LLW because the rifled barrel is longer and IMO the build is better. FWIW, I like the concept so much I have an LLW 22 11 oz. barrel on the way for my RFRO gun.

Everglades is a 124 at about 173PF. It works well and doesn't break the bank.

Absolutely. None. There is no shooting involved. I do those things to make sure the RO dosn't have to even come close to making a judgement call. As far as I'm concerned, it is 'best practices'. I RO A LOT, and appreciate that in a shooter.. SCSA is easy. ROing USPSA is a lot tougher. There are a lot more rules, and a lot more judgement calls.

After talking with them this morning, I decided to go the same way. I ordered the 22 barrel for a build I'm assembling. I had planned to do the same for the PCC. However, the one I want is only sold with a barrel and comp. If I can get it with the Lead Star 16" pencil barrel and comp, I'll do it and swap out the barrels. Unfortunately, the only ones coming in have the BSF 16.1" barrel and comp. That's $449 for the barrel and $79 for the comp. I'll have to think about that.

I was going to respond to several of your points, but you are too worked up about this. Think of it as avoiding a judgement call. Sweeping any part of your body except the lower extremities while holstering is a DQ. Even then, the safety must be on and the finger clearly outside the trigger. There is no judgement involved. The RO doesn't have to think about extenuating circumstances.. It's the rule. It's a DQ. USPSA rules apply unless specifically countermanded by an SCSA rule. Uncasing your gun an placing it on the table is a very, very bad practice that could have consequences other than sweeping. Suppose you drop a mag and go to pick it up. You are farther than 3' from the gun, so DQ. BTW, I have my holster set up so that no part of my body is swept while holstering and unholstering. In SCSA I do not unzip a case past the muzzle, so there is no way I can sweep myself when uncasing or casing unless I do something really stupid.

I'll second JEM Guns frames. Vastly superior to the STIs I used.
