I shot the rounds after work today, rounds number 18 through 25 on the new barrel. It's just breaking in/settling down, and I am still getting familiar/comfortable with the new set up. The hand/stock/bag relationship is still a work in progress with it, but I think I'm figuring it out. That came together almost immediately for the Matrix when I first shot it, I really like that chassis stock a lot. This whole rifle handles a little different, and is lighter, I will be getting a weight that fits in the gap between the stock and the riser. That will balance it better as well. So still getting used to it.
I wasn't planning on setting out a target, just shooting and getting numbers, but I ended up doing so. Results are not conclusive, barrel is breaking in, I'm getting used to the rifle, etc.
Impact Action, Altus smithed Bartlien barrel, Manners PRS1T stock, TT Diamond Pro Curved trigger, ARC rings, Steiner Tx51 5-25X56 scope, Atlas Gen II bipod.
RL-155 Powder, Berger 105 Hybrids .010 off the lands, CCI-450 primers, Alpha non OCD cases
89.0 Degrees, 65.5% RH, 29.68 inHG, 2673 DA
32.4 Grs = 2905 FPS
32.5 Grs = 2907 FPS
32.6 Grs = 2897 FPS
32.7 Grs = 2925 FPS
32.8 Grs = 2927 FPS
32.9 Grs = 2929 FPS
33.0 Grs = 2947 FPS
Not bad, and the barrel should speed up around 100ish rounds. The two cases (32.4 & 33.0 Grs) with light ejector cutout marks (The Alpha non OCD cases heads are softer and show ejector cutout flow sooner than Lapua 6 BR cases) were from the first firing with RL-15 and a different bullet breaking in/cleaning for the first 17 rounds. I shot one cleaned, shot three cleaned, shot seven cleaned, then shot the rest of the 17 rounds. That was the first range trip. I did not clean before shooting these today. I will clean before I shoot it again, then it will be clean after matches.
I'll likely load up three each of 32.7, 32.8, & 32.9 next.

First three shots on the left, last four on the right.
Primers look great. Lots of round still left on the edges.
