You are on the right track as far as accuracy. With enough testing you can usually find a factory that will shoot satisfactory groups, but there is nothing like "Rolling your own" for accuracy and performance on game. I load for 17 Hornet, 17 Fireball, 204 Ruger, 22 Hornet. 222 Rem, 222 Rem Mag, 223, 22-250, 6BR, 6 PPC, 243, 25-06, 257 Roberts, 6.5 Grendel, 6.5 Creedmoor, 6.5PRC, 6.5 Rem Mag, 270 Win, 270 WSM, 6.8 Western, 7mm-08, 280 Rem, 7mm Rem Mag, 7mm WSM, 7mm PRC, 7mm WBY Mag, 30 BR, 30-30, 308, 30-06, 300 WSM and 300 Win Mag. I probably left out a few and that is just the Rifle loads. It is not a cheap habit if you try to do it right but it is very satisfying.
