I’m shooting a 300 Weatherby Mark V non brake, which has large jump and I have finalized my charge weight of H1000. The gun is shooting .7 moa at 100 which I think is pretty good for the amount of recoil, but I’d like to try shrink this down to .5 by adjusting seating depth. I have Berger 215 hybrids loaded at mag length, how much should I adjust seating depth given the amount of jump already 50 thousandths?

I think I'd try several different primer brands at this point before I jacked with seating depth unless you've already done this.
-
That would be something to try. I’m using GM215M primers, but I don’t have any other magnum primers to test. I do have federal 210m.

Man, inside an inch with no brake on a 300 weatherby and looking to shrink the group. Definitely out of my league. I can shrink them by up or down .01 grain ladder if they have a good brake.
-
I appreciate the feedback, I may be asking too much. After this season I plan on having treads and a brake installed. Reducing the recoil would help a lot.

I find it helps to shoot my groups @ 200 if my scope and the weather allows. I’ve had some tight groups at 100 grow quickly as I go out but a tight 200 seems to hold and track good. In your case I’d recommend more of a target style brake that doesn’t require timing since you are very good with recoil and they’re not quite as obnoxious.
