For me, tuning the loads to the rifle makes all the difference. Especially for hunting rifles. I have a Win mod 70 that my dad couldn't get to shoot. I worked through the loading process and now it's a 3/4" gun. Totally confident in that rifle and would take it on any hunt.It's pretty easy to make good ammo, start with the best components and keep everything the same. A digital scale is a game changer, weigh the bullets, case and powder as components and then weigh them after assembly. Keep everything within a grain or 2 separate and use them for keeps, practice with the others. Truth be told you probably won't see any difference especially when using a hunting rifle.
The Copper bullets work great, but they're $1 each.
