Extremely well in short barrels From Bear Creek Arsenal

by Jimmyjams, Verified Owner from FL, United States Written on March 20, 2026
I was a little worried after seeing a video of two different short barrel pistols not cycling in the ammunition. Once I got to the range to test it out it worked flawlessly. I did not have any issues with loading or unloading. I did not have any issues with ejecting or cycling in the firearm. It made my platform perform as if it was a 45 ACP .shooting regular ball ammo out of a 7 1/2 inch barrel makes a concussion that is unbearable and flame shooting out the front but this ammunition makes sense for this set up slow rounds flawless functionality.
