Horde,
I need some help troubleshooting my Maker 95 GR TREX H322 Recipe. Here's the story. Ran some factory ammo to dial in the new scope 3-12 Vortex Diamondback HP with Hornady 123SST and Underwood 110 Controlled Chaos. Both shot great .375 and .400 respectively, 2 groups of 3 shots each. I run an oiled patch and 2-3 dry patches between each load. Shooting at 50 YDS bench, bipod, bag. 16-inch ARP 3R barrel.
New Hornady Bulk Brass which I ran through the press to uniform the neck, champfered and deburred
CCI450 Primers
2.260 COAL
H322 0.3 ladder from 27.0-29.8 no powder compression, no signs of pressure
Maker 95GR TREX length 1.68-1.60
Groups were 2-4 inches with the exception of 28.6 which had two touching and one an inch to the right. No consistency in POI.
Best I can figure the projectiles were unseating a bit as they ran through the action. I was thinking of seating them at 2.245-2.250 and loading 28.6 of H322 and retesting. If I get good results, retest the ladder starting at 28.9 checking for compressed powered and stopping there.
FYI, Shot another 3 shot group of the SST and Controlled Chaos after working the Maker 95GR TREX loads, and got the same results, great groups on the bull...Did this for a sanity check to see if the scope was the issue.
All suggestions and solutions are welcomed and greatly appreciated in advance.
