Been trying like the devil to get 210 gr. Nosler Partitions to shoot in my Model 70 XTR with no luck. Went through IMR 4350 and RL 19. CCI 250 LRM primers. I'm going to try 4831 next, and if that doesn't shoot, I'm going to have to change bullets. I'd like to get this worked out before the weather turns warm, so my development will be at temps. I'd be hunting in. That may or may not happen, tho...... The only difference between shooting a whitetail with the .338 and having it get run over by a truck is that there are no tire tracks......
