Got a change to test out some loads this morning out of my 18" Shaw barrel and it still likes the hot loads...
All were loaded in previously fired Lapua brass and had CCI41 primers, 5 shot groups.
120 SMK's loaded to 2.20' and 123 Amax's to 2.250':
120 SMK w/28.5 8208 XBR,
Avg-2503, ES-19, SD-10.3
3 @ .5 moa but 2 others opened it up to 1.5 moa
123 Amax w/28.5 8208 XBR
Avg-2498, ES-57, SD-22.7 (4 of the loads had an ES of 16)
1.08 moa, 3 @ .271 moa
120 SMK w/31.0 CFE
Avg-2484, ES-55, SD-21.1
1.4 moa
120 SMK w/31.5 CFE
Avg-2543, ES-42, SD-15.2
1.5 moa but 4@.697 moa (I always have 1 that mess things up)
123 Amax w/31.0 CFE
Avg-2489, ES-85, SD-31.3
1.5 moa
123 Amax w/31.5 CFE
Avg-2522, ES-43, SD-18.5
4 @ .84 moa (1 flyer)
My rifle shots the 123 Amax load with 28.5 8208XBR as well as it does factory Hornady ammo, and it also seems to like 31.5 CFE223 under either the 123 Amax or the 120 Nosler BT. Primers were getting flat, no cratering, but for some reason the CFE loads caused a lot of FTE's where the next round did start to chamber but the fired round stovepiped. I might want to try a heavier buffer if I'm going to shoot more CFE (which is very likely).
