Bad groups with BL-C2

[ErikS]

Just a PSA. The Hornady X volume has a load for 123s and BL-C2. It just gave buck shot patterns instead of groups in my rifle. I did have good luck with AR-Comp as others have noted here.

My BCA 16 inch stainless barreled upper gave me about 1 MOA when I did my part.

ErrikS,

What range was your Min./Max charges for the 123 and BLC2. I found a node with BLC2 for my 20” but was at a lower fps than 23.8gr. of 8208 with the same bullet. Might also check that something vibrated loose on your Rifle.

Got up to 29.5gr, never better than 2MOA. AR-Comp worked well and showed real potential.

My 308win AR10 loves the stuff, slow but little groups for me.

Mine likes 30.0 grains of blc-2 with everything I have tried.

Grendel can be picky about powders it seems, mine does excellent with BLC-2 and AR Comp but not so good with CFE.

I got back out with it today. It did ok on my second trip. I think the bad groups were me. I got consistent 1.2 MOA from the BL-C2 but saw sub MOA from AR-Comp. As others have noted here, 27.6 grains of AR-Comp seems to be the ticket.
