Good info here! Another thing to consider is if his rifle shoots good or better than good with factory ammo, I'd be hard pressed to not stick with factory. By the time you get the basics to load 100 rounds, you could easily have a few hundred rounds of ammo on hand.I always hate to discourage someone from getting into reloading, but unless you’re going to shoot volume rounds of 243, you’ll be better off financially paying $2/round to buy factory ammo.
If your just looking for an excuse to get into rifle reloading, I think this would be as good a reason as any.
I had a rifle that wouldn't. I mean horrible 1.5" with the best factory I could get. It does this now. 5 shots with a cold bore
