Finally narrowed it down to a 270 winchester,Which I have always been fond of, or a 270 short mag.Basing the short mag on 200 FPS increase.Has anyone chrono'd any 270 winchester loads and 270 short mag loads in the t3.If so I would appreciate your findings.I am aware of folks talking about the velocity loss with the throats and the t3s.I have a t3 in 223 and with the loads I have chronon'd I havent had a loss in velocity in this caliber.All loads were within factory specs as far as speed.I thought maybe it was a problem only with the short mag cartridges in the t3 but I'm not sure.I think I'm leaning towards the 270 winchester and figure the velocity and bullet drop between it and the short mag out to 300 yds wont be much of a difference anyway.I'm just hoping the 270 winchester doesn't have a velocity loss because of the t3 throat.Anyone that has a t3 in either of these 2 calibers and has actually chrono'd some loads,I would appreciate your input,And anyone elses for that matter.Im getting one or the other in 2 days.
