I need some help working up a load. The last time I did this it was a disaster. This is for an AR. The various loads I made shot 4 to 5 inch groups. The rifle shoots 3/4" groups with factory ammo.
I need help with the proceedures and where to start.
This time I'll be using AA2200 and Winchester PSP bullets (I bought a few thousand). Later I will do the same using a Vmax 55 grain. The manual list 23.5 as max for a 55 grain bullet. Where do I start (grain wise)and at what increments do I move up?
Thanks for the help
