I have a Savage Desert Tactical in 6.5 Creedmoor ( I know, I know 😉). Loading a 140 grain Elite Hunter. Limited to 2.86 in mag. 2.95ish puts me at the lands, so roughly. 090 off the lands ( I want to use the magazine).

My question is when doing a seating test, starting at the mag length, what intervals of increasing depth should I try? .015" steps (because its a hybrid design and therefore less sensitive to seating depth), .030", .040"?

I only have two other rifles with dbm and was always lucky enough to find a good seating depth that fit in the dbm using the "Berger method".

Any insights are greatly appreciated.
 
Load to mag length, find the best shooting load and, if necessary, go deeper by .015". This is the method I use and it's yet to fail.
