[QUOTE="Mysticplayer, post: 29229, member: 8947"] Jon, I am working up my 300Ultra mag and can offer some advice. With H870, the load is around 100gr w/ the Accubond. With 240gr MK, the load is 98gr. All this in my rifle which has a long throat. Use with care. I have found that these ball powders, although very cheap, can be a pain due to being temp sensitive. For fall/spring shooting, they should work just fine but forget about using them in the hot sun unless you are willing to adjust loads on site. I have now experimented with H50BMG and my rifle seems to really like it. Being a new generation powder, it is temp insensitive and should work well throughout the year. Yes, much more expensive but shooting these cannons is not cheap to begin with. I would rather spend a few more bucks per box and hit at long range then not. Want to get some vel numbers on this powder and 240gr MK. Hopefully, it is faster. Jerry [/QUOTE]
