.223 Sierra 80gr HPBT Seating Depth

[Jet]

Put a 28" 1:7" bull barrel on a rifle with a .223 Wylde chamber. Broke the barrel in with Hornady 75gr HPBT and did some load testing. Got .75" to 1" with multiple powder charges and seating depths.

Just got 500 Sierra 80gr HPBT and do some load work up for it. I'll be using Varget, Lapua once fired brass and 205M primers. For those of you who shoot/have shot this bullet, what seating depths have you found work best. In the lands or backed out?

Thanks in advance for the help.

I had the best results 10-20 thousandths out. Tried them jammed 10 all the way out to 50.
