SPECIALLY MADE COMPETITION QUALITY LOADED 50 BMG AMMUNITION FOR ALL THE BARRETT RIFLES! No one makes loaded custom rifle ammunition like we do! No one!
At Arizona Ammunition, LLC. we are primarily a custom ammunition shop fitting/tuning ammunition to specific rifles but we do offer a little bit of “generic” one size fits a specific brand of rifle. This is NOT surplus. We have tested this ammunition made of this specific rifle(s) and determined the correct specifications required to make this loaded ammunition the most effect and accurate. You will find the powder charge, brand of powder, and overall length will vary from brand of rifle to brand of rifle. Each chamber will be a little bit different. The construction of this custom 50 BMG rifle ammunition is done 100% here though. In most cases the manufacture has loaned us one or more of their 50 BMG rifles to test and develop accuracy rounds for it. How do we do it?
1. We generally use once fired brass case preliminary PMC or Lake City that has a late headstamp date on it. On request we can use new 50 BMG brass cases of WCC, CBC, RWS, and others but the cost will go up at least $1.00 per loaded round.
2. The brass case goes through complete recycle processing. When we finish with it it is NOT the same as it was in the beginning.
3. We trim the brass case.
