dsbarrios1 Wrote:Hey guys, Im needing some assistance and hopefully I can find the right answers. I just built a 6.5G and I have a problem with it Flattening the primers and pierced Primers. I have a Aero Precision Lower with a Kynshot 5000 Hydraulic Buffer, BCA 16" upper with a seekins Adjustable gas block and a Odin Works Atlas 7 Compensator. At first I thought it was my ammo which isnt the best in the world, PPU Rifle Line 120gr, but then I switched to Hornady Black 123 gr and only 1 pierced primer out of 30 rounds but the primers were still flat. I plan on removing the 3 key changes and add 1 by 1, Buffer, Gas Block, and comp, to see if I can see a difference in the spent cases. When I first built the gun I never bothered to notice if I was having this issue as the thing had alot of recoil and decided to replace the above items. Any thoughts on where my issue may lie?[ATTACH=CONFIG]19906[/ATTACH][ATTACH=CONFIG]19907[/ATTACH]
What is the origin of that PPU ammo? Specifically where and when did you purchase it? PPU recalled a bunch of their Grendel ammo several years ago, and then it was off the market for a while. Is it possible you purchased some of the old recalled ammo? I see you pierced a Hornady round too, so looks like more than one issue but, it also looks like the overwhelming problem was with the PPU???????
