Home Forums Reloading Big Game Rifles Seating depth trial

OK, did my seating test today on the Tikka T3x, 6.5 Creed using 147 gr, ELD-M bullets, 41.1 gr. of H4350, Lapua twice fired brass and CCI 450 primers.
One thing I have found with this rifle is that if I load to max magazine length I'm jammed .020" into the lands per the Hornady OAL gauge.
I used the Erik Cortina method, starting .020" off the lands (this puts me .040" off max magazine length) and bumping back in .003" increments.
Here's the results. I made two scope adjustments which are noted on the target. All I'm looking for here is group size, I've already settled on my charge weight at 41.1 gr. which is right at 2,650 fps.
I'm going with load #3 which is .026" off the lands. I'll shoot some at distance and hopefully the groups hold.
