You got a great thread going here. I am a new guy back in accuracy shooting and reloading after about a 30 year lay off. Got into trap shooting and some of you know how that goes, turning out a shell with every pull of the handle and a 25 inch kill zone. Well I'm back, only wish I still had those 35 year old eyes! Just got a smoking deal on a Cooper TAC 20 so I'm out in the shed measuring loads. I live in SW CO so there is some dog shooting and we have a great club rifle range. Wait a minute, I'll get to the point. Seems like the 32 Vmax is the popular bullet in the Tac 20. I just ordered some 40 grain Bergers, hey, I like to tinker, bought a pound of 4198 and some Varget. The 32 seems tried and true but what about the 40g B's? I know, get your ass on the bench and figure it out yourself. I would like a hint. I also have a pre 64 mod. 70 in 6mm, custom barrel from way back in the 60's, gun belonged to my grandad. On paper it shoots ok but I may want to rebarrel one of these days, staying in . 244 for those 60-75 g bullets for breezy days. Anyone who can figure out what I am talking about post a reply. I think I am going to enjoy this group. Thanks, exdimmerjock
