Oh man you broke them off, I understand exactly what your talking about and that probably hurt. I can see how one could sand it down to make it look alright. I'm glad you received one with the proper gauge because I did come down on them about it, I was a bit embarrassed after stating 230 BAR in my review but I only went by what I knew. What kind of performance are you getting??
I'm getting some pretty ridiculous power! My reg was set to shoot the 34gr heavies at 880-890, the HST didn't buy me too much more (I was filling to 230 like you were though). I wanted to see how far that I could push it with the stock parts, so I figured out the reg adjustment, measured it end to end (73.74mm from the factory), played around a little turn at a time until eventually it went down to around ~73.42mm. That gave me a little under 165bar. I've since scaled it way back.
I had to add a few washers for pre-tension, after all was said and done, my LabRadar and chony reported some crazy numbers. The highest with 34gr JSBs was 990fps (74FPE), and 1003 with the JSB MKIIs. For fun, I shot some 25gr JSBs and Murphy's law kicked in, where twice I heard the crack of them breaking the sound barrier, but my LabRadar said "sorry, I didn't see that" on both of them!!! The highest I clocked one was at 1117fps, but my LabRadar seemed to have issues that day with the 25gr pellets, specifically.
I saw your video shooting NSAs @100y, I was hoping to be able to get out and get some similar groups as you did. Unfortunately, the wind here in the PNW has been *brutal*! I've only made it out to my usual long range spot a few times since I got it, and each time the wind has been unfavorable
Anyhow, didn't mean to long wind that or thread hijack! Nick Nielsen told me the 39gr NSAs shoot really well out of his friend's .25 HM1000X, so I ordered 1000 to test. Another member here is going to send me some custom slugs with different diameters to try as well (weighing in the low 40's to upper 40's). I have another thread in the PCP section that I'll update with my results. Hoping for calm winds this weekend, but we'll see what happens
