I was really surprised to see talk of using filler with TrailBoss. It's an interesting powder in that it can be used in almost everything and the main caveat is DO NOT COMPRESS it. You can basically fill the case to where the bullet will sit and go.
Sounds like you are getting good results...
I'll be loading for the 375H&H first. At some point in the future the other calibers may get loaded.
Just didn't want to buy 8 pounds of something and NOT be able to use it in other great big cartridges.
I have some XMR-4350, so maybe RL-22 will be what I get.
Looking for powder suggestions for loading the BIG magnums.
Calibers that I'd like to consider would be:
375 H&H
338-378 Weatherby Magnum
340 Weatherby Magnum
416 Rigby
416 Taylor
Basically all the big stuff just under 50 BMG.
What do you guys like/suggest?
Looking to load some 300gr Sierra Soft points. I have Varget, 748, & Benchmark on hand. What I don't have are magnum primers.
You guys have any data that says I can load some rounds with standard primers?
