I've been using H4350 and 150 BT's in my A-Bolt for years now hunting MO whitetail deer but I'm looking for an off season project with the 140 Accubonds. Right now, I'm considering using Nosler Custom brass, 140 Accubonds and probably H4831SC. If you were to load this combo or if you've had experience with it, what would be the optimum range of powder weights to try out? I'm thinking in the 56-58 grs. range possibly. Whaddaya think? Thanks for any help!
