It's all lot number ,I think. I have your exact setup- got it a couple weeks ago. I had some center x and SK Long Range on hand. Both were ok, but not great. I didn't really measure , just picked the better of the two for a match. I sent the rifle to the Lapua test center and got the results yesterday. They (Devan- great guy!) started with 20 lots at 50 meters. Narrowed that down to about 12 at 100m. Narrowed that down to 2. That's a lot of 10 shot groups. I picked from those two based on standard deviation ( which they measure in distance- which I think would translate to velocity. Ask one of the experts on here for that) . The lot i picked at 50 meters shot 14mm ,23.8mm, 21.6mm, average 20mm (about .75 in. )with no subtracting diameter. At 100m - 25mm, 37mm and 48mm- about 37mm average (1.5in or so) . Some of the other lots tested couldn't even put 10 rounds in the 60mm circle, if i understand the results correctly. I wasn't super excited but he told me that was about average for the RimX's he had tested. I bought some for a couple reasons. 1. What else are you going to buy right now? 2. I have a known accuracy for a couple years of matches. Now I know what to expect. It should be plenty accurate for NRL22. I sold my Vudoo, but in my mind I had some SK standard that shot .9 at 100. Looking back though I'm sure I subtracted .22, and I probably cherry picked a target, and that was at 100yds.
I asked about putting my can on- he said expect your results to go to crap ( my words). He said he has only had one customer who said his results improved. Hope that helps with your accuracy expectations.
Nice pile of gear! You are missing a mag extention!
