You just never know what you'll find when you go digging around your ammo stores...
I stumbled across an ammo can containing 2 unopened battle packs and 1 opened, but full, battle pack of the 5.56 ammo pictured below.
iirc I've had this since the early 1990's. I've not had much success locating it on the interwebs. It's 344 A 86 5.56 Ball M1A3 in 300 round battlepacks. South African maybe?
Anyone familiar with this 5.56?
Thanks in advance,
Here's the question. I cast 100 .452 RNFP (Lee Die) 255gr bullets. Because of the high antimony content the bullets averaged out at 222gr. What if any considerations should I take into account for the weight difference? My first thought is that I would stick with 255gr load data as the size of the round is the same thus limiting case capacity. I would assume that velocity would more then likely increase since weight is different, unless the bearing surface of the bullet actually has more of an effect then the overall weight. Anyways, let the speculation begin.
