Re: 6.5x284 loads, anything but 4831

Well, that is strictly a hunting load, and again 1 fps ES and 1/2 inch groups at 200 yards with a 16x scope, thats pretty much as good as I am. It places 5 touching at 100 yards. I tried everything but BR2 primers and only because the only BR primers I can find without ordering and paying hazmat are 210Ms. I got the best consistency and groups with RL17 with Fed 215 primers. I figure that likely has something to do with the pressure difference,to some extent at least. When just shooting I use the H4831SC load and it does about the same regardless of the primer I use.

    Yeah using a 215 is almost like adding an extra grain of powder and a more erratic ignition, plus lapua cases are thicker and softer than norma cases, the normas will hold just a tid bit more. Jam those bergers in the lands and try 49-50.5grns Imr 4350 with 210m's or BR2s and I bet you can't see how many holes you left at 100yards until you see how raggedy the 3/8s hole is on the back of the target! That is quite a mean hunt load you got though, 1K deer and antelope nightmare!

I have hit 3176 with 51.5grns Imr 4350 but it started vertical so I backed it off for accuracy, went from 8" groups to 5" groups, so I guess the question is why use about 10 grns more powder to do the same thing?
    How do you go about measuring that 35 pound neck pressure?

    That was going to be my question.

    Funny you asked this question. I have been using h4350 and was getting good results but at 48g it was showing slight pressure and was only getting 2850 to 2863fps. So I borrowed a little retumbo from a friend using it in a 338 edge. 57g was showing some pressure so I dropped to 56.5 today which is almost a compressed load with 140 bergers. I am getting great groups and ES now and its down to either winchester(2993-3004fps) or 210m (3031-2991fps) primers in lapua brass.

    I shoot a 6.5-06 that pretty comparable to the 6.5x284 ballistically. I use H4831SC. Try RL22 with is about the same burn rate.

    Is the Hodgdon data on the conservative side? I am working up with H1000 and Hornady 140gr sst and it sure does not look like Im going to get close to 2900 fps. Hornady says I should get to about 2700 with 52.5gr H1000 and that seems close to where I am at. I do have a 24" barrel, maybe longer barrels is how everyone is getting closer to 3000.
