BTW, it is a 1:8 twist, true 16" barrel.
Remington 7 1/2 primers
27.0 to 27.4 grains of Reloder 15

This cartridge will pretty well measure the potential accuracy of your rifle. (Well really, you and your rifle.) 27.0 grains fills the case to the bottom of the case neck, 27.4 grains fills it to the top and it's too easy to spill at that level. 26.8 grains doesn't generate enough pressure to seal the case in the chamber well, the case body will have soot. Speed from my 24 inch rifle is a little over 3200 fps.
Reloder 15 is slow for this weight bullet, right on the ragged edge of usefulness, hence the full case. It shoots great.
