7MMRM seating depth for Nosler 160 Accubonds?

[MTGunner]

I purchased a Mountain Tactical extra magazine for my Tikka T3X rifle. If have measured the magazine to find that I can seat the Nosler 160 Accubonds further out of the neck and still be able to fit cartridge in magazine.
So, my question is how deep are others seating there 160 Accubonds off the lands? The SAMMI depth suggests 3.290. In the factory magazine I can seat these at 3.300 and still fits. These group 1” @ 10 yds. I am looking for a bit more accuracy out to 300 yards and perhaps beyond. MTG

Start. 020 off of the lands. If that won't fit the magazine Start at magazine length and work back. I'm assuming you meant 100 yards and not 10. Just realize you might not get much better than moa.

Yes, 100 yds. But, looking for improvement out to 300 yds. MTG

That's the only path you have, ... except change in charge weight or powder choice.

I always do a powder ladder test chasing horizontal, then bullet seating to tighten group.
