Good gracious! ...one heck of a crimp on those 7.62 NATO rounds! Do they chamber well in the SASS?
I wonder how the manufacturer gets this crimp? They must use a tool that simply squeezes laterally around the case neck, instead of pushing the cartridge "in-line" like with a bullet seating die used by most reloaders.
We've pulled bullets from ammo like this before and they're pushed inward at the crimp so much that it MUST affect accuracy at several hundred hards. There is NO WAY the bullet is even close to being concentric after that! But for a couple of hundred yards, it's "probably" acceptable accuracy.
Good gracious! ...one heck of a crimp on those 7.62 NATO rounds! Do they chamber well in the SASS? Maybe the photos don't show it well, but that's just gentle crimp into the bullet cannelure, just like reloading dies can do. Match ammo just has a friction fit, but these rounds are designed for abuse in MGs and rifles. The rounds are NATO-spec, and marked so. I had no problem at all with them in the M1A, but I know they're not up to match standards, and were never intended to be.
I have antique ammo with the case mouth staked to the bullet, and some with a three-piece horizontal crimp at the case mouth. That had to take a special crimping die.
