"I've got an old Rem 788 in 6mm Rem that will shoot 1" or less groups with just about any load I come up with so I know the cartridge is capable.
No brag, just fact"
Unfair comparison. The remington 788's are known for being tack drivers. I have a Remington 788 in .243 and can shoot 3/4" groups at 100 yards most of the time. 1 1/4" on a bad day. The rifle is a real shooter.
The remington 788's are great rifles. Remington quit making them because they were out shooting the 700's (or so legend says).
"no brag just fact" You are right.
I load, 9mm Luger, 38 and 40 S&W, 38 Special, 357, 45ACP, 45 Colt, 223, 243 and 30-06
