Hey guys new to the forum but have been reloading for a good while. I would like some other opinions on a load I've got going. I have a savage 110 ba that was bought immediately after they were released and am well aware of the tight chamber issues they had. The load I'm running at the moment is a 250gr scenar .020 jump over 90 grs of retumbo fed 215 in lapua brass. 90 grs is a starting load for this combo but I'm getting a touch over max book velocity at 2880. No real pressure signs but have pretty flat primers. Fed 215s seem to be a little soft in my experience but will a tight chamber cause that much of a jump? Some primers are pretty flat some not so bad....

338 lapua velocity vs charge weight

This brass is on its 3 loading. The only thing that concerns me is the flat primers. If I get away with a low charge weight and good velocity because of chamber then so be it. Any opinion on the primers?
Its probably headspace related. If there is enough headspace, the primer backs out of the pocket during early part of the firing cycle. Later on the case head comes back to meet the bolt face and squashes the primer flat.
Ok I be been wanting to check headspace as it is so now I've got another reason. I feel that I'm within reason on velocity and was looking for other pressure signs but they're not any. If any other opinions I'm all ears
This is apples and oranges but in my 338LM with a 28" barrel, I get just over 3000fps from factory Lapua 250gr Scenar ammo.
