Saw large mags a few places today online. Hopefully this is the start of the re-stockening

I got a bunch of Fed GM215M recently and am going to try some in Lapua large pocket 6.5 Creed brass tomorrow. 144 Berger Hybrids. H4350. Hope I don’t blow my face off. Any charge weight suggestions?

I'd back off about 1 full grain of your currentload, then load 3 each in
.1gr increments.
Color your tips and shoot at 1 aiming point at your regular tuning distance.
I find it amazing on what .1gr charge weight difference does on paper.

^^^^^ What he said . I had to end up with a drop of .3 off a load when changing primers .

Thanx Brett, I shot a few pressure test rounds this morning. Funny but Magnums seem to make no or very little difference in pressure. Think I’ll pack it in for a while, 90 deg this morning and we’ve got some 118, 120 deg days ahead. Cheers
