Doing some preliminary research on my next reloading project, the 340 Weatherby. Going through reloading manuals I was expecting to see very slow burning powders such as RL-22 and H1000. I was surprised to see 4350 and 4831. The rifle is an Accumark and has shown preference in the past for 250gr. factory loads over 225 grain loads, so I'll be starting with 250's. Thought I'd ask here for suggestions as well.
Thanks in advance.
