Re: if you could only use one .338 bullet, what would it be?
Yeah, 3340 is smokin' with a 250. The rifle has a 30" barrel which seems to give me a good 100 fps gain over a more typical 26" tube. Still, it is a pretty hot load and I have to be careful with it in hot weather. I always keep my rounds in a cooler to keep them from getting too hot sitting on the bench in the sun.
When I work a load with the new barrel that's coming, I will probably back off a grain or two, or switch powders. I don't have any pressure signs with the load other than I only get about 5 loadings before the primers get really lose. WBY / Norma brass is pretty soft and the case shows no other pressure signs and will still be fine except the primer pockets. Brass is expensive, and fireforming is a pain so I plan to give up a little speed to see if I can get 8 or 10 loadings rather than 5.
