I tested some Remington Core-Lokt today in my 264 Win Mag. Its been the only available ammo I have been able to find at a semi reasonable price. I have some boxes of HSM in the 140gr Gameking and 130 grain Berger VLD plus a few Nosler Trophy Grades 130 grain Accubonds. Everything but the Remington seems to have more recoil and punch. It feels like I am getting more velocity from all the other brands but the Remington recoil is pretty tame. Have you notice any performance differences or lack of performance from the classic Remington Core-Lokt?
