  1. Did the lighter bullets work better for you than a heavier 115 or 124 grain? I tried some blazer brass 115 grain factory ammo to see if that would be better than my 124's but recoil was much harsher and dot movement was slightly worse.
  2. This is probably the biggest driver of what i'm seeing as I still have much to learn about shooting a rifle fast. I've been actively working on getting away from the more traditional stance and being able to drive the rifle but still have some old habits to break. Shortening the stock definitely has helped but still have to ingrain driving it into the shoulder and clamping down while on the clock. At the end of the day I know no amount of load development is going to make all that much difference in my scores, but the engineer in me can't help but want to optimize the mechanical system as much as possible. Seems like I'm on the right track, how did the hotter 124 grain loads behave? Did going above 3.8 start getting a different dot movement, harsher recoil, etc?
  3. Ever since I built my PCC earlier this year I have not been able to achieve the dot tracking that many here describe. I originally loaded a 124 grain everglades plated bullet to 130 pf (3.2 grains PrimaV) and called it good for load development and have run this load for 1500-2000 rounds without issue. I've seen others here mention that hotter loads worked better so just for kicks I loaded up some test rounds at 3.5 and 3.7 grains and went to the range to shoot pairs. To my surprise the 3.5 was marginally better than 3.2 and 3.7 was significantly better that either of the other loads. Typically I get dot movement up and to the right but at 3.7 the dot tracked straight up and down and returned faster. My question is from your testing what has been the ideal PF to shoot for in your builds? I debating if I should continue tweaking or just leave it at 3.7 grains and call it good, but was curious where I was compared to what others have found as ideal. I don't care about recoil, but am focused on minimizing dot movement. Obviously bolt, buffer, recoil springs will play into this but ideal loads will likely be similar. For reference I have a taccom extreme bolt with the weight installed, taccom 3 stage buffer short stroked, rifle spring that came with the buffer, hiperfire 24C trigger, and MBX barrel with pinned comp.
  4. I second this, the hundo is a tighter than most chambers and most slight failures (not sticking out to the extractor grove) will function just fine. Check them in you barrel and you'll probably see that you're good to go. Bullet diameter can affect this, when loading .356 coated I get 2-3 per hundred that don't sit flush but with .355 plated I might get 1 every 300. Sent from my Nexus 5X using Tapatalk
  5. I picked 70 grains of lead out of my comp after the first 250 rounds of coated bullets though my pcc. Decided that was not something I wanted to deal with regularly and switched to everglades plated. Over 1000 rounds later and I have 0 lead in the comp. Sent from my Nexus 5X using Tapatalk
  6. I second this, for me polymer gun = 147 grain and steel framed stock 2 = 124. Ultimately one or the other is not going to give you any advantage and comes down to personal preference. Load up both to 130-135 pf try them out and decide for yourself. Sent from my Nexus 5X using Tapatalk
  7. Thanks, from reading the rules I figured option one was the appropriate one. I've seen a lot of option 2 at local matches and wanted to double check that I hadn't missed something that explicitly allowed it. I don't want to get complacent with "get away with it at locals" habits that will get me in trouble at a larger match.
  8. This may be a naive question and hopefully not too far off topic but for those with carts when do you load the pcc on the cart upon arrival to the range? Do you take it bagged to a safe table like you would to holster a pistol or load the flagged rifle directly from the car? Thinking of making a cart to not have to carry multiple bags all day and don't want to break any rules. Sent from my Nexus 5X using Tapatalk
  9. While I can't comment on the experience of others, the mbx lightweight barrel has been working great in my build. 1 inch group at 20 yards (without putting a scope on probably the best I can do as a shooter) and a great feel and balance when coupled with a lightweight handguard. Only have about 600 rounds through it so far, but have had 0 malfunctions. Only time will tell it's long term performance but I've been very pleased so far. Sent from my Nexus 5X using Tapatalk
  10. Was doing a little reloading last night and I did a quick check of my powder stock and realized i'm down to my last 3lbs of Prima V. PrimaV and PrimaSV seem to be out of stock everywhere from what I can tell. Does anyone have any information on if or when more will be coming into the country? I'll be reaching out to some of the usual suspect suppliers as well to see what they say but figured someone here may have looked into this already.

  12. I purchased the MBX lightweight barrel on Black Friday for my PCC build. After seeing the previous thread about people having poor accuracy with these barrels I was very concerned that I had purchased a lemon. I was finally able to get my new build out to the range today to sight in and test and am pleased to report that I had nothing but good results. I went to an indoor range and took my standard 9mm minor ammo (125gr BBI TC, 3.5gr PrimaV) and shot 250 rounds with zero malfunctions. I shot a group for accuracy at 20 yards (longest they had) sitting on a stool with the front supported on my range bag and no rear support. Using a Holosun 510C with the brightness turned down to get a more accurate aiming point I was able to shoot a 1 inch 5 shot group which considering the imperfect shooting position and my group shooting skills I thought was very good. The only negative I can speak to after my short experience is that coated bullets are going to be a serious no go with this comp. After only 250 rounds I picked over 70 grains of lead out of the comp and it was smoking like crazy compared to how the exact same load performs in my pistol. Guess I'll have to move to plated or jhp because I definitely don't want to have to dig lead out of the comp after every range trip.
  13. To follow on with this any tips on loads that you guys have seen work well in these barrels? Bullet weight, jacketed vs coated, power factor, ect Sent from my Nexus 5X using Tapatalk
  14. Probably won't be until after new years but ill be sure to report back. Sent from my Nexus 5X using Tapatalk
  15. Well crap, I just bought one of these for a new build. Hopefully it was just a bad batch. Sent from my Nexus 5X using Tapatalk
