Well , I guess I'll toss in my .02 worth . . . .
Today was the first decent day we've had here in some time . It was about 60 , and bright and clear , with about 5-8 mph winds and low humidity. We're about 500ft above sea level here at Kamp Krusty.
I'd finally found some 123 SST's and A-Max's , so I thought I'd try some IMR 4198 loads out.
The rifle is a Franken-AR , LaRue trigger , RRA lower , with a Grizzly side charger upper with a Leupold 6-20 x 50 LR/AO. She has a 264LBC chamber in a 20" Lilja 1-9 that my buddy chambered and machined for me some time ago .
Hornady virgin brass
123 gr A-Max
CCI 400 primers
2.250-.255 OAL.
I made three different loads , 23.5 , 23.8 , and the winner at 24.1 grains .
The two lighter loads were both 'meh' , at about an inch . . . . but the 24.1gr load was decent , with five shots into two ragged holes about a half inch apart .

I adjusted the scope , four clicks right and two up , and shot another 5 shot group at the 1-inch circle . . .

Not as neat as the first , but I wont complain.

There's no signs of cratering or anything else , so I'll try a couple steps hotter and then fine tune what I come up with .
I love this rifle in this cartridge , I should be able to shrink her down to a single ragged bug-hole , now that I'm in the ballpark , with some experimenting with 8208XBR and CFE223 . . . . once I can find some locally .
