Re: 300 wsm

H1000 won't get you great results. You won't be able to get enough in the case for maximum performance.

IMR 7828ssc is my new favorite powder in the 300 WSM. It is about as good as I have found for the slow burners and the ES in my loads have been fantastic. I worked up a 210 Berger load with 7828ssc last week and I had six straight duplicating velocities with one particular powder charge. I thought maybe the chrono was spewing some foolishness until I went to the next powder charge and started getting very close but different velocity readings for each shot again. I have found 7828 to be insensitive to temps ranging from 25* to 80* in loads using the 210 VLD and the 230 Tactical.

I like 4831sc for the 200+ bullets too, but the speeds on 7828ssc have been a bit better. I use a standard CCI 200 in Norma brass for all my 300 WSM loads now.

I have worked up some good loads with RL17 and the 200 Accubond as well, but they got a bit squirrely in hot temps. Great hunting round though.

Great choice on going with the heavies in the 300 WSM, they really sing with the high BC bullets.

Do you guys think the 215m federal primers will work well. I have a couple thousand of them from other loads so It would be nice to just use those. Thanks for all the great advice keep it coming too.

I use federal 215m primers and h4350 with the 190 vlds. She is a tack driver.

Give them a try. For best potential results don't commit yourself to one type of primer just because you have a couple thousand. Try a few different primers and let your gun choose. If you find that the 215s work well enough, then run 'em. Primers aren't the magic potion to turn a crappy load into a miracle round, but if you need to shave an ES down to shrink your long range groups, a primer change may just be the answer.

I am running 67 grains with fed 210 match. I started at 64 grains and worked up. Try your 215's but you may find better velocity spreads with a large rifle primer. I am running the 208's at 2950.

Do you think H-1000 would work in a 300WSM built on a long action? Being able to seat the bullet further out would allow for a heavier charge weight. If you had one in a long action how would you load for it?

It's doable. A drop tube would help with a bullet seated to the boat tail transition.

When I tried loading the 230 berger with H1000 in the 300 WSM, the charge I needed filled right to the base of the neck at 71.5 to 72.0 grains with a drop tube funnel. You could be talking a full 2 grains more powder for the 208. The Norma case will hold approximately 74.5 grains of H1000 filled to the top.
