6 BRA neck tension recommendations?

[A.Thomas]

I always follow Alex’s recommendations with known combos so started with 5K and after I found the powder and seating for this barrel, I shot a tension test.
I’ve tried the higher node but this barrel won’t tolerate it so went back to the lower one.
My load is:
Lapua brass (.265 loaded round)
29.7 H4895 (faster lot) 2928FPS ES-12ish
BR4’s
Roy 103’s -7K from touch

My issue is I don’t have any known to start with. I probably complicate things more than they need to be just trying to decide where to start

I would try around a .259 above and below. Sell the amp, and neolube....or that's what I would do anyways.

Here's a ladder at my new 1,051 ysrd spot in a 4 picking up to 5 moa wind this morning. I run a 260 bushing on a 268 neck reamer with .107-8 neckwalls. Loaded rounds are .265 plus a little depending what bullets.

Your new spot looks down right tropical compared to the old spot

Cracked me up this afternoon. “Sell the AMP and the NeoLube” I use the lube on my grandson’s trains. . It’s perfect. What do you have against the AMP annealer ?

What do you have against the AMP annealer ?

Nothing at all, as that's the only annealing machine I kept around...but I haven't found annealing in general to produce the grouping abilities i look for.

It seems the AMP has become the default tool for the big guns
