What are your thought about picking the bullet weight for a Noslert BT and powder based upon the ft/sec as it leaves the muzzle. Nosler recommends no faster than 3200 ft/sec for best performance. I estimate that 3300 out of the muzzle would probably equate to 3200 by the time it impacts a white tail deer at 50 yds. I do not expect to shoot closer than 50 yds. The bullet weight could be 130 or 140 and the powder must provide a good grouping but 3300 out of the muzzle.
