Re: 6.5 sherman shortmag field test

Got my new magneto speed today so gave it a test run to see what the SS would max out at with 7828. 58 grs. was absolute max and turned up 3219' with a 142 Matrix ( 26" barrel). Not bad for a Creedmore length case The mag speed is really slick and easy to use.........Rich

Dang, that's VERY hard to beat. Well done on the case design.


Did accuracy fall off at that speed?

Yes, but I don't know how accurate 7828 will be anyway? I haven't had time to play with it yet. I shot some RL 25 today at just under 3100' that showed some real promise and there was room for more velocity.....Rich

Good question Rich. 7828 has performed well for me in 300win & 338RUM but those are slightly different animals

Rich, I've been following these threads with interest. You guys have done some great work. I got to see Rhian's SS and loaded cartridges in Townsend. I've been thinking about a short action 6.5 SAUM for a while.

If I might comment on the RUM and WSM velocities. I've been able to push 210's to 3130 max with Retumbo in my RUM and 180's to 3200 plus in my 24" WSM with RL17. I suspect it might do well in your SS as well. In any case, very interesting and well done.

Are you going to nitride this barrel?

Hi Mark! Thanks for the compliment. The velocities I posted were pretty much the top out of reloading manuals and I don't doubt you can do better with hand loads. I'm not sure on the nitride yet? Only so much $$$$$ to play with.......Rich

Yeah, the Berger manual seems to be a little conservative. Do you know what barrel length powder they were using for the RUM data? Most guys I see loading the RUM with 210 Bergers and Retumbo are getting in the 3100-3150 range in a 26" barrel. Nosler's online manual shows 3050 with 210 partitions which have a longer bearing surface using RL25 out of a 24" barrel. Not sure why any bullet or powder manufacturer would ever use a 24" barrel for RUM testing?

300 Remington Ultra Magnum — Nosler

The standard 300 WSM powders do produce velocities in the 2950-3000 fps range for 180 bullets. But RL17 really does well in the WSM case and gives me 200 fps more velocity than H4350 with the same pressure. I suspect it will do well in your SS also.

I don't mean to detract from your thread but I thought I would give a little more perspective on the comparison.

Carry on with the good work
