Re: 7mm STW Reloading Thread

Safari,
I'm getting under .5" groups at 100 and under 1" groups at 200 with the best being in the 3's at 100 and 5's at 200. These are all 3 shot groups.

    The Berger manual says 75 grains is max load but I'm sure they are conservative. My question is how much over their max can I expect to go? I see a bunch of people going 5 grains over Berger published max with the H1000 and 168 grain VLD but nothing with R25.

    Details of my setup are: rem 700 with 9twist 26" bartlein barrel. 76 grains R25; rem and win brass; cci 250 primer loaded to 3.670 COAL.

    I haven't seen pressure signs at 76 grains but just want to get an idea of how hot I may be able to go to get to 3,200 fops or so.
    79 to 80 gr should be safe with the 160's ..... But as I have said many times before on this site ...... If it's shooting like that "leave it be" ..... Run your tables off of those numbers and call it a day

    You are absolutely correct. I have a very good load in my pocket and if I can't get the velocity and accuracy by moving up I am going to go with the "slower" load.

    I would suggest you calculate the fps gain you have been getting per grain or .5 gr of powder as you worked up to 76. In my experience, I have found that as your load gets too hot you will see a definite decline in the velocity you are getting relative to the charge increase (diminishing returns) Accuracy may begin to degrade also, but you will definitely see an increase in ES & SD after you reach that point.

    Settled on a load.
    Cooper model 52 26 inch barrel

    83g rl 25
    145 lrx Barnes
    .25 off land's
    Critical item for me was switching primers. Winchesters would leak gas at 3200fps rem 91/2 m are fine.
    3500 sea level chronnyed.
    Scared to try for anything faster. I believe I am at max velocity.
