RL17... It boosted velocities in my 300 WSM by 200 fps over H4350.

Like most that have replied I use H 4831sc in my 23" barreled 7mm WSM
and H 1000 was to slow and fouled bad in the short barrel.

I might have tried a hotter primer for the H1000 but the 4831sc worked so well
I gave up on the H 1000.

Thanks for the help guys. I appreciate it.

p.s. What is going on with the powder supply? I looked to try and find this stuff and it's nowhere.

We have powder here, but it's a little sparse at times.

I was getting 2980 fps out of my 23 inch barrel. I was pretty happy with that for a short barrel breaks walking gun.

Re: Need Powder advice on 7MM WSM

In a 24" 1 in 9 twist Lilja barrel these are my velocities with the 7mm WSM.

With the factory Winchester supremes with 140 gr accubond = 3261 ft/sec.

The H 4831sc load with the 140gr accubond =3347 ft/sec and a .177 5 shot group.

The H 4831sc load with the 160gr accubond =3009 ft/sec My Elk load for walk hunting.

I would have listed the powder charges but they should be worked up to.These loads
are stout but not MAX.
