That definitely could have happened. Even though I spent most of my time in the 130-140b range. Which by modern standards, is not that high when you market your gun as slug capable.

Between squalls here so 80yards will have to wait but the Krait with the 110bar tune is making 890 with the 18.1 grain (32fpe), so maybe it would stretch to shooting the 25 grain. I can’t say yet if the JSBs or JTS are better but here’s the group at 50 yards.
3/4 in sticker and no flyers. 10 JTS 18.1 domes

Finally had some calm conditions to try the Krait at 75yards. The delay allowed me to get a solid tune for the JTS 18.1 at an average speed of 908fps. The reg pressure ended up at a smidge over 120bar on the gauge and the plateau speed was ~936, so it was tuned at 97% of plateau. This gave a very solid SD (~2) which was robust across the range of tank pressure (280-140bar) and it passed several cold shot tests again with no loss of speed or point of aim. I played around a little with the valve tensioner and found that 1/4 turn from full tension gave the best ES. Backing off more than one half turn started to degrade the crispness of the shot sound. This is an 8 shot group with one pulled by me to the left.
I need to futz a little more with the trigger, which has one of those confounding adjustments. Out of the box, it had only a tiny first stage and the instructions mention only second stage adjustments. A video from CDR explained how to increase the first stage LOP but that adjustment also affects the sear. I need to futz around with it to find the sweet spot.
I think I can say at this point that it clearly passes the test of accuracy and cold shot capability as per my needs. A couple annoying minor gripes are that the butt pad rotates around 20degrees and I can’t budge the bolt that holds it. The JTS 18.1s shoot lights out but are a little resistant to chambering. JSB 18.1s load smoothly but are markedly less accurate and the ES opens up. Haven’t tried anything else except Hades, which were also very good. The other minor annoyance is that the fill probe is difficult to insert and remove. Probably best to leave it in and cap it. Finally, I’ll say that I miss the heft/solidity of the M3 a little, shooting from a rest. I’m currently using a lightweight Optisan 3-12 and I’d likely switch to a heavier scope, which may help. On the plus side, this little bullpup shoulders really well and would be great in the woods. I’d say it’s rather like a Lelya and the Ghost is going to feel a lot more like the M3. I’m excited to get my hands on one this week.
