I have two, both cut with same reamer, 6.5-284 Lapua brass:
27" PacNor 1-8, 117 DTACs are precision in this one
30" Shilen 1-10, 87-90 gr Bergers
Brass life is very good, other than a few that get a little beat up during ladder testing....
Size with single pass in Redding sizer, turn necks and use same brass in both rifles.
Best thing to increase barrel life, run a patch or two down the tube, after every 5 or so shots....barrels are cheaper than bullets.
No matter which one you pick, you will like it.
The terrain sure looks a hell of a lot different whe you'er crawling through it!
