We don't buy 338LMs to make tight groups at 100 yards... that's a ridiculous application for these guns. We buy them to do business at 1000+ yards, that's where the rubber meets the road.
I like putting six rounds in my my mags... I used to single feed too, but now I want to practice getting back on the gun faster and seeing if I can put subsequent rounds faster with corrections from spotter.
btw, doesn't it take quite a bit of time for your steel to settle once you hit, given those springs... why not just use chain which would dampen quicker? </div></div>
I tell guys that seating the bullet to touch the lands or stuffing it into the lands does not guarantee you better accuracy. Usually it does but not always. You have to play with your gun/barrel and seating depths to find out.
I usually start my guns .010" off the lands and go from there.
My .338 Lapua on my test rifle and shooting some box Ruag 250gr. and 300gr. factory loaded ammo. I don't remember the dimensions for how much the 250gr. bullets had to jump to the rifling but the 300gr. bullets I do remember where jumping .100". Yes a .100" not .010. Both factory rounds shot great! The best 250gr ammo group came in at approx. .269" with one pulled round opening up the group to around a .450". All of the ammo both kinds (I only had 20 rounds of the 300gr and 40 rounds of the 250gr. ammo) I didn't have a group go over .750. All shooting was done at 100 yards.
I say up to .060" the gun can shoot better than touching the lands.
Play with the seating depth you will be surprised sometimes!
Nice gun and groups by the way!
