Re: Ball powder vs. grain in the 30-378 wby
Ball Powder such as H870 and WC 872 works fine in any large overbore case.
The wear factor is "MUCH" better then the large stick powder such as 5010. We found this out many years ago.
I know of one 30/378 owned by a LR hunter at Williamsport that was shot out in 400 rounds using the BIG stick stuff 5010 which is much like 50BMG.
I use nothing but the WC872 in any of my LR Hunting rigs and that includes the 6.5/300 Weatherby, 7mm Mag, 7/300 Weatherby Mag, any of the 30 Cal mags and improved 30s such as the 30 Goodling and 30 Bear, 30/378, 300 Tomahawk and of course the 338/416 Rigby Improved. I don't use Moly bullets in these rifles either.
I once took a rifle (30 Bear) to Bruce Baer to have the barrel set back because I thought I had enough rounds through the barrel to warrent a set back. After checking the bore he said I really didn't need to do that because it didn't have many rounds through the barrel.
He said that barrel couldn't have more the 500 rounds through it. When I told him it had near 2000 he couldn;t believe it. I only shot WC872 in that rifle.
Ball powder works for me and I get many rounds through a barrel before I have to rebarrel. It is heat sinsitive and seems to work best in hunting conditions and colder weather like 50 degrees and below.
If trying to shoot 1000 yard matches in "hot weather", ball powder seems to want to give you a flyer or two in a 10 shot string. Hence, heat sinsitive.
Glad to see your getting the results you are out of the H870 powder. I did use it in my rifles before switching to WC872. Works great in my Tomahawk. WC872 is just a tad slower. Not much though.
The smell of burning gun powder makes me horney. So does diesel smoke. [img]images/icons/wink.gif[/img] [img]images/icons/shocked.gif[/img] [img]images/icons/grin.gif[/img]
