Has anyone loaded or used the 223 Sierra Gameking 'Superoo' 55gr 1365K projectiles?
How do they compare to the standard SGK 1365 in 55gr as found in the OSA Buffalo River SGK? The only (physical) difference I can see is that the Super Roo projectile tip looks slightly more hardened/uniformed than the factory loaded Buff River SGK ammo. I've bought about 6,000 rounds which I'm going to handload for my Remington 700 in a Magpul Pro 700 chassis.
Thanks in advance. Richie.
