338 Edge seating depth: how deep is too deep?

I am having a new barrel installed on my Edge and am contemplating an Accuracy International/CDI detachable magazine setup for the "tacti-cool" look and to have 5 in the magazines. This magazine only allows a COAL of about 3.750".

I seated both a 300 gr Berger and SMK that deep and those bullets are taking up a LOT of space in the case. My last barrel allowed 3.875" COAL.

Will there be any issue with this? I'm not concerned if I loose some velocity. I have a 29" barrel on order so 2800 fps is all I really would like but if this is going to create a major handicap, I might just pass.

Thanks.

This isn't built on a Remington though or else I'd be all over that.

Thanks.

Re: 338 Edge seating depth: how deep is too deep?

When you seat a VERY long bullet like the 300 Berger that deep you are certainly reducing the case capacity jamming the bullet so far down in there. When case capacity is reduced, pressure rises. I don't know how much velocity you would be giving up over a longer seated bullet, but it would be some for sure.

If you are not worried about the velocity loss, I can't think of anything else that would be problem.

There are probably others who can answer "how much" better than I can. Obviously, if you have access to a 338 Edge a little experimentation would be fun and informative.....

3.750 will work just fine my edge with a 28" barrel with the bullets seeded at 3.750 with the 300 smk I get 2840 fps

What powder are you using? I think I will try it. Again, I am really only after 2800 fps.

Thanks.
