That is true, AoA advises against changing Reg pressure. But, on my .22 with just the power wheel, I can go from 880 FPS with 18.1 grain JSB to over 1000 FPS with the 25.4 grain RD Monster. Honestly, no reason to change reg pressure... However, it is externally adjustable should you go that way... I don’t know about 80 FPE, but I do know it will easily go to over 65 FPE with the reg set to 130 bar, which is my factory setting. 80 FPE would not be unreasonable with increased reg pressure IMHO.
Would the LCS shoot the cheap Wal-Mart Crosman Hollow points decently by only adjusting the power wheel? YO!
I go with Huben K1, better trigger, more compact, and can shoot both pellets and slugs with very good accuracy. LCS SK19 shoot pellets awesome. Both gun can shoot pallets or slugs over 1000 fps. If you want long distance shooting go with Huben K1 and shoot them with Varmint Knockers 28.50 gr slugs.
That's a 2016 video and I "think", or at least I was told by a Huben AG dealer, that Huben is on their 3rd rendition of rifle barrel. Supposedly this latest one is made to shoot slugs and pellets well???
