Re: 7mm rem mag sendero
I may be wrong but it should be a 1n9 or 1n91/4. What bullets are you trying? What powders? What primers? Try this one on for size 64 grains H4831sc rem 91/2mag or CCI 250 primer, 160 accubond. That load should give you 3000 fps and under 1/2 inch 3 shot groups at 100 yards if not post back and I have quite a few more. Let me know the bullets you want to try and I probably have a load for them.
Guns and ammo, what more do we need?
