I have a can of IMR 4831 from the 70's I wonder if I can load the 139 Sp boolet with the above powder?
I read a few post on IMR 4350 would be the better choice but it seem from the Lee Manual the both powder run the same loading data except for cup pressue the 4831 at 46.0 grains is about 3880 4350 aound 4450

you sure can....work up to a max of 47 grains..... and you should be about 2,700'/sec.

It's a great powder in the 260 w/ 120gr so I don't see why it wouldn't work well in the 7-08 w/ 140-150gr too.

If you do a Google search under Hodgdon, you can access their data for the 7mm-08. I think you will find that 4831 is too slow for the 139gr bullet. They do not list 4831 until they get to 154Gr bullets.

I'd suggest Varget or 4350 w/ a standard length barrel or 4895 if your barrel is a little slower. Kudude

i have loaded the 7-08 for about 15 years now, i like to use powders in the 4064, RL-15, varget. H-380, 4320. range.. i for one dont like high compressed loads i like to stay about 95%.. my lyman book shows 52 grs of RL-19. you cannot get 52 grs in a 7-08 case, it runs over the top, i stick with RL-15,, all with 140 gr. bullet.

IMR 4831 would be a good powder with a 175 grain bullet in the 7-08. Not so great with the 139.

I use 50.2gr of IMR4831 in the 7-08AI, but stick with 4350 in the standard 7-08 (as much as I can cram into the case). Both are very accurate.
