Changing bullets will likely change the load performance quite a bit. You'll need to work up a load specifically for the Bergers. I started off shooting the 140 gr Bergers. They shot my smallest group, but were not consistent for me... or maybe I wasn't consistent for them. Anyhow, I tried the 142 gr SMKs and while they haven't shot the tiniest group, they are very consistent 3/8-1/2 MOA. At least they were until I recently had to change both powder and bullet lot. All #ell broke loose then. Went from 3/8-1/2 MOA to 1-1 1/4 MOA. Time for some tweeking.

The smith sent some loaded 142 SMK, and they shot about the same as the bergers... Where do the bergers like to be seated to shoot really well, or is it going to matter from rifle to rifle?

Seating depth alone will not make any bullet shoot well. Each barrel is different, and you will have to work up a load for that bullet in your barrel. Normally, Bergers do like to be jammed into the lands a bit, but it is just something you will have to experiment with.

The load I'm shooting with the berger is very consistent with in about 20 fps between about 20 shots. Its just that first shot is always flyig out and the 2nd two group really nice.. So do you think that could be the seating depth of the bullet?

Are you using wind flags? They are very important.My 6.5 did not like 142smk's compared to 140 bergers.H4350,n165,are both good powders.

3 shot groups are not groups, and you can't tell a thing from them. You need to shoot 5 x 5 shot groups, and measure the aggregate. That will tell you how you load is working.
There is no magic answer such as only changing the seating depth. Everything works together....

H4831 sc, cci 200 large rifle primers, norma brass, 140gr berger bullets... using redding competiion dies.. we do use wind flags and try not to group on windy days....I'll try messing around with the load and shoot some 5 shot groups and let you know what happens... any other suggestions welcome.

To get a good 5 shot group the first 3 need to be good.
