RL .243

If I recall correctly, isn't the 270 a necked down 30-06 So the same damage as a 30-06 sounds about right.

.270 is a .30-06 catridge case necked own to .277

.270 is a .30-06 catridge case necked own to .277

Shotgun News used to have ads for a .270 barrel for the M1 Garand.

Those barrels can still be found. I have toyed with the idea of doing a build with .270.

what range do you have them at right now

.270 should be comparable in range to 30-06 since it has flatter trajectory than .30 caliber.

As for .243 is based on the .308 case but has smaller bullet so it shoots flatter also at longer range.

I guess it depends on what "magnum" range is.....they shoot 5.56 (77 grain bullets) at Camp Perry 1000 yards

I have them at standard range by FFS. Magnum range is x1.2 (that's MY fudge, not GDWs).
