Re: 338 edge accuracy issues... input wanted

I had this gun build specifically for the 300 Grain berger bullet and I'm not getting any results back not happy..with H1000 I get 2777 to 2815 retumbo I'm 2852 to 2899 . So if I set the bullet farther back I'm losing more in the speed department.. but if I can't get this to shoot maybe I need to change bullets??

I think some of you guys need to talk to your smiths, they have more experience with these cartridges than you and should be able to address some of what your experiencing or determine if your going about something the wrong way, load issue, gun issue, ect.

If he is unwilling to help, you chose the wrong smith to build your rifle.

Try seating it back, could not hurt and I would be willing to bet you don't lose as much as you expect. I run standard (short) chamber with 89.0 of h1000 in a 24" barrel and still pull 2780 and have more available if I wanted it.

Something you may want to look at.
When reloading are you annealing your cases and what amount of neck do you have, also what is the concentricity of your loads??
With my Edge the Remington cases are annealed every second load, neck tension is .0015 and loaded run out is .002 to .0025 .
Using 90 gr H1000 215M primers with 300 Bergers at .015 off lands and it shoots
sub-MOA at MV 2750 , SE 13-16.
With my new Brass from Shawn Carlock, Bertran 338Edge brass, same load information the MV 2815 with SE less than 10. and my groups are tighter.
good luck on finding the problem.
Charlie

i'm using remington brass and i'm not annealing it.. My next load i'm trying is 4.030 to my ogive with my comparator which puts me at 3.885 oal.. Shawn told me 5 to 10 thousands off the lands.. when i use my oal gauge i'm at 4.100 i went five to ten thou back and no good... We'll see what happens now.. Thanks Charlie

Most of the hybrids I have shot 6,7, and 338 all like between 0.015-0.020 off the lands. Just some more free advice.
