I've shot roughly 20 rounds thru it in one quick little trip with a buddy. He brought his chrono but it had dead batteries lol so I wasn't able to get any velocities. As far as shootability goes it's really nice. Super short and very little recoil. I think my 18" 6.5 creedmoor has the same recoil. I only loaded up pressure tests to shoot also. I tried imr 4350, h4350 and retumbo. Didn't hit any noticeable pressure with the imr but also stopped at 55gr. H4350 I went to 56gr and only at 56gr did I get a little ejector mark on the brass (no heavy lift). The retumbo hit pressure at 58 or 59gr but I think that's just way too slow of a powder for this cartridge in this barrel length. I wish I had velocities but like I said his chrono was left on on accident and was dead. My same buddy has some hodgdon h4831 for me to try next time out. I was planning on shooting hammer bullets out of this rig but I might stick with these 143 eldx if they shoot good. Didn't shoot any groups since the loads were just pressure tests. Just started huckin bullets at a couple rock faces at 580 and 945 yards. Impacts on both with guesstimated velocities in my hornady app. So far I'm really happy with it but I need to get back to loading and shooting it. Had covid last week so just laid low. I'll probably try and shoot this next weekend when I have another 3 day weekend.
