I would avoid the ammunition with bi metal jackets.
I think people need to put it into perspective.
Are you going to shoot 10,000 rounds through your rifle? I've built comp guns for local guys that have over 10k and accuracy is just starting to suffer. These rifles were 1/2 MOA rifles that now shoot little over MOA. Rifles are shooting brass cased 55 gr copper jacketed bullets with some 77's thrown in. Powder is TAC.
Now, what's your typical range session like? And how many times a year do you shoot?
Barrels cost 100.00-300.00, maybe more for a super premium fanboy driven and marketed barrel. These uber expensive barrels with the goofy fluting don't shoot any better than a 200.00 plain Jane barrel.
Where is the trade off? That's up to you, but I don't think that shooting a couple hundred rounds a year is going to cause any issues and if you are able to shoot more due to cost that's good.
