Hey guys,
New to reloading and am looking for info on seating depth of bullets. I'm shooting a t3 22 250 and loading 55 and 40 gr. vmax using varget. Is there a rule of thumb for starting length? Should I start at the manuals OAL or should I start right off the lans? I have roughly 0.125" between lans and recommended OAL. Projectiles and powder are not an issue but just don't wanna be loading a whole raft of trial rounds when there may be a better way. Considering there is no abundance of brass the fewer wasted fires the better.

I went with book coal on my tikka 22-250. got a nice .3 load at 100y tried playing with seating dept at 200y to improve, made it worse. played with grains powder up and down and found 34.2 varget 52g bullet 200y .3 groups.

If it was me, I would start with bullet 20 thou off the rifling, and then make sure it would fit the mag at that length.

Thanks for the advice. Take all I can get . No prob with mag length. Seems to be lots of mag room right off the lans. Pretty much decided to load a few at oal and a few on the LANs. See how that pans out then split the difference and experiment with charge weights
