Damn that load seems a bit over the max to me. Are you seeing any pressure signs? I have loaded XBR in 3 grendel barrels now and at 28.5 grains I started seeing serious pressure.Looks like I'm going first.

While i suspect not many will play with 100 grain Amax, I have a box and decided to burn some imr8208 today in my 18" JP barrel.
POI and velocity, there definitely appears to be a node at 30.0 grains and possibly a step or two above where I stopped at, 30.8
If you can't see the velocity readings they are as follows:
30.0= 2712 SD-3 ES-7
30.2= 2733 5/10
30.4= 2742 9/19
30.6= 2775 14/26
30.8= 2782 15/28
If OCW theory holds, +3% of 30.0 = 30.9 so next time out I may try 31 grains, but given the numbers and group at 30.0... thats very tempting to remain there.
Padom, I seat all my bullets between 2.245-2.250what's your COAL roughly? And what is your max COAL with say a 123 Amax or 123 ELDM touching the lands?
I see st the top of your target it says 2.245 COAL...How far off the lands are you?
Have you had an opportunity to target test these loads? I'm very interested in the 6.5G and this bullet in particular.This just arrived...
Velocity testing 107 loaded to 2.258, this leaves them jumping .097" in my JP's chamber. 18" barrel, rifle gas.
will punch some paper next.
Okay but not great. Dots are 1"... going to explore some slightly lower charges and 28.6 next. If that doesn't tighten things up I'll try 8208.Have you had an opportunity to target test these loads? I'm very interested in the 6.5G and this bullet in particular.
Where’s node in terms of point of impact for loads? One round sample or multiple round average? Consistent poi for a multiple of loads a better indicator of node than two loads with similar velocity. Interested in your further results.
I’m hoping mine does too.18” Aero Precision barrel
