All have to be seated way short of what they should be.
And where, praytell, is this?
6mm Creedmoor SAAMI maximum COAL length is 2.800” Hornady reloading manual- 105gr and 108gr loads tested at 2.790” COAL
In my rifle, 105 BTHP, touches at 2.625” COAL. I can force the bullet in deeper to 2.780” COAL
108 ELD-M, touches at 2.675” COAL. I can force the bullet in deeper to 2.742” COAL
All measurements are short of the SAAMI 2.800”
I hope the issue is what greydog posted earlier and the gunsmith can get it corrected. I have only shot 1 of the factory ELD-M and didn’t have any pressure signs but I won’t shoot anymore until it gets checked out.
I have been shooting my 105 BTHP loads and they do pretty well.
