I have found that my Savage classic likes the 140gr the best. I have harvested deer (all mulies) from 250yrd to 20 yrds with various manufactures bullets with excellent accuracy from sierra, nosler and barnes (MRX) now unavailable due to high manufacturing costs. I use H-380 and RL-15 (Rl-15) took 1/2" off of my group and is cuurently my favorite powder with h-380 as my backup. I always load slighly under max in the mid 2600's fps Im not hunting Rino's im shooting for accuracy. I have harvested my Buck 3 of 4 years with a grand total of 4 rounds spent. I use seirra, lyman books and Hogdens online loading guides.
Federal and CCI primers and Winchester brass. My suggestion, load 15 rounds of several combinations, find one you like and shoot, shoot, shoot
