Never had a bolt handle fall off but I've had 2 223s that cratered primers pretty bad, even popped a couple in one rifle.
The loads were in no way hot
Folks who actually shoot,notice things that exist,while those who "shoot" their Imaginations and Pretend do not. Mainly because they can not. Hint.(grin)
I've only had a coupla dozen 700 bolts bushed,mainly because I prefer LRP's when an option. Hint.
Typical .378" S/A OEM Big Green scenario. Tolerance woes,as opposed to "pressure" and positive headspace a given. Note outer primer radius. Hint.
Same Lot of ammo,in same rifle,after Greg's work. Hint.(grin)
Re-purposed O/F R/P Bulk,in formed cases. Though I haven't shot said rifle in but a coupla days.(grin)
Now as an over the counter NIB OEM 700 receiver goes,I'm at ease in procuring same and going James spout for the win,less fanfare...assuming LRP.
