I have a 16 inch 338 win. mag. barrel for my encore and all the loads I can find are for rifle rds. The only problem I have is the waste of powder and the muzzle flash. With the slow powders used for rifle I can start fires fifty feet away.
The best load so far is 55grs. of IMR-3031 of 60 grs. of IMR-4895.
Any help would be nice
Rick
