Chris I think you posted the website for Bartlett before but can't be sure. Also where do you find loading data for the WC872?

Texas

Use the H870 data.

You can go about 1 to 2 more grains of WC872 if using 100 grs or more of H870 such as when loading the 30/378 or the 338/378 or 338/416 Rig IMP.

Thanks DC hope that you might try out that Sierra 250gr SMK and let us know how it works in your 338/416.

texas-- Check the archives--DC has posted some results awhile back on the .338 250SMK; Its doesn't fare to well against the 300 gr., the BC is much lower and the 300 really packs a punch at extreme distance...
The Bartlett website is here... http://www.gibrass.com/

Re: Ball powder vs. grain in the 30-378 wby

I've been running around 105 gr of H870 through my .300 Tomahawk and it isn't any dirtier in this gun than some of the stick powders. I also heard that H870 was discontinued, but I intend to order 16# of WC872 from Bartlett in KY. It has a very similar burn rate and costs only $40 for an 8# jug. It is surplus 20mm Vulcan powder, but it is new, not from pulled rounds. I found out about it from DC, as this is what he uses...

I wouldn't waste "my" time with the 250 gr 338 Sierra MK in my 338/416 Rigby with the 37" barrel. The rifle was built for the 300 gr and the results are unreal. If it's not broke, I won't fix it.

The 250gr only has a .5 BC and that's not anywhere near what the the 300 gr produces and not good enough for the ranges I like to reach out with my 338/416.

The 250 gr 338 would be for a smaller case OR a large case with a shorter barrel such as 30" or less where you can't get the desired velocity out of the 300 gr bullet.

Ray Romain uses the 250 Gr in his 338/375 (just an improved Weatherby case) Case and has a 34" barrel. We teamed up on a Colorado Mule deer this past season and he got it at 1800 yrds with his rig. The bullet arrived with 800 Foot pounds of energy and after closer inspection penitrated both shoulders and exited the far side. The exit hole was very small being about 1" diameter.

His shoots very well, but won't hold a candle to the 338/416 with a longer barrel, 300 gr MK and larger case as per energy and velocity at extreme range.

PS---Chris, how do you like those legs Jim makes? They are top of the line.
Someday I'll have to show you how the Cam and crank shaft gears and chain work on my table for the elevation.
