Looks for Match

Looks for Match (2/11)

  1. Just got another case from BBI. Ordered Saturday on my doorstep Thursday, can't ask for any better than that especially in today's climate.
  2. I agree, when I went to the range my intention was not to test for accuracy until I start noticing I wasn't shooting as accurately as normal. Shot some of my old load to ensure it wasn't me and I was able to consistently get groups half the size with Prima V compared to Sport Pistol. If I'm seeing that big of difference at 7 yards I would assume the difference will only be more pronounced at 20 or 25 yards which would be a better test.
  3. I recently ran out of the last of my Prima V stash and bought some Sport Pistol to replace it due to the many good reviews I've seen on it. I used the same BBI 125 TC and 1.110 OAL that I used with the Prima V and worked up a load with the chrono settling on 3.8 grains which gave me 130 power factor out of a Stock 2. Feel is basically identical to my previous load and both have an SD around 10 fps. However, when I shot them for groups I'm getting consistently poor accuracy compared to Prima V at the exact same velocity. I was only shooting at 7 yards but shooting the 2 loads back to back the Prima V loads were in 1 large ragged hole and the Sport Pistol would open up to around 2 inches. I thought it was me at first but I shot 6 groups alternating between the two loads and the results were consistent. Has anyone else had a similar problem with Sport Pistol or other powder having reduced accuracy? Was there anything that you did that was able to improve the performance without having to switch components? My next thoughts are to try different OALs to see if that will improve as maybe I just got lucky with my initial Prima V load. Or try upping the powder charge a little and see if it improves at a higher velocity. I'm curious what others experience has been so I don't waste trips to the range chasing my tail adjusting something that will likely have no impact on the performance.
  4. I had a similar experience, BBI order was shipped the next day but took usps 3 weeks to deliver. Sent from my Pixel 3a using Tapatalk
  5. 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.
  6. 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?
  7. 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.
  8. 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
  9. 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
  10. 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
  11. 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.
  12. 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
  13. 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
  14. 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.
