IMI 77 OTM RazorCore is extremely accurate ammo. I handload all my ammo but a friend bought a few cases and gave me a 20rd box to test one day at the range. I shot a 2.5" 5 shot group at 500yds in my 16" WOA 1:7 Recce rifle.
buy with confidence. And crimps are no big deal and no different than LC. Buy a $10 RCBS crimp reamer off Amazon and chuck it up in a drill. One and done.
