Re: 300RUM Loads
I use the exbal program to do models on different bullets at different velocitys at my altitude and temp using the BC numbers listed and compared. I am looking for speed and thump out at 1000yds, not that I would actually shoot at game that far except at hogs [img]/ubbthreads/images/graemlins/grin.gif[/img].
Anyhow,if you get the Berger 185vld going 3400 which I did with 97gr. of H1000 you get 1461ft/lb. If you get the 200AB at 3260 which I did with 91.5gr. of RL25 you get 1521ft/lb. RL25 was very consistant 3263,3267,3261. However I do not like using this powder for the extreme temp sensitivity characteristics that it has. Retumbo was to hard on primer pockets trying to get respectible velocity.
Now check this out, if you get the Berger 210vld at 3100 which is very easy to do with 91.5gr. of H1000, or 94gr. of Retumbo you get 1530ft/lb of energy at 1000yds. I would rather stay away from RL25 and it's quick to pressure and temp sensitivity and be healthy to shoot another day and be satisfied with a Berger 210vld at a modist velocity.
For what it's worth anyhow.
