6.5-06 best powder for 140gr. Bullets

[Fred Ea]

I am having a 6.5-06 built for target- hunting and wondering what powder gives the best velocity with 130gr.-140gr. Bullets. Any 6.5-06 owners out there with any suggestions.
I have a bunch of IMR4831 and IMR7828sc on hand if anyone has a load with these on hand. Any help would be appreciated.
Thanks,
FE

I shoot Retumbo in my 6.5-06AI's. But H4350, 4831, Retumbo, and Ramshot Magnum are all good choices.

Your 4831 and 7828 are both very good choices.

IMR4831 = 46 gr to start out ... it depends on WHAT 140gr bullet.
IMR7828 = 49.2 to start, again depending on what pill you use. Both of these are upper, but SANE, loads so it might be a good idea to drop about 1gr below and shoot 1 round to look for potential pressure sign just to be safe. Honestly, the 7828 may very well be THE powder for the 140gr pills

I recommend Win. LR. Primers 100% for sure with either of these powders.

Have a good one,
Gary

Mine loves 140 Bergers and RL22. Just saw a report on a guy running 7828SSC with great success as well though. Another one to consider is H1000. Good luck

+1 to H1000 it is one of my go to powders.

I use H4831 on two different 6.5-06 rifles. One a tactical setup with 142gr SMK's and the other a sporter with 140grn Accubonds. I'm getting and ave .5" 5-shot groups from the tactical and .6" 3-shot groups from the sporter. The H4831 also seems to be stable over a wide range of temperatures.

H4831sc is a really solid powder choice. I like most of the Hodgdon Extreme powders. Personally I will take a high degree of consistency over a broad range of ambient conditions over pure velocity any day of the week. Fortunately with H4831sc you rarely have to compromise in this area ||
