FINALLY had more than a few hours tonight and not on call so finished up my Crown build!
Decided I wanted a hi power build so started with a new FX Crown Continuum in .22 and from there upgraded to a Gen 3 Huma hi pressure reg and installed the Huma pressure and reg gauge for accuracy.
Installed a brass hammer weight and upgraded hammer spring guide (Earnest Rowe has videos on YouTube about this).
Backed off the internal hammer spring adjuster a turn and a half from max and this is what I got!
18.13 on 177/.22 BLAZING fast....Once I had the power wheel down to 2 average was 940 on 1 920's and grouped exceptionally well!
25.39 Redesigns well over 1000 FPS on max with the transfer port set to .177/.22 and on power 3 was in the 950's and grouped even better than the 18 grain from power setting 3-1 as well as the corresponding positions on the letter side of the wheel!!
33.95 Beasts 890 on max and decent groups as well!
FX Hybrids as well as JSB Knockouts both did outstanding in the high 900's on power level 5 down to the mid 800's on power 2.
This testing was done with the 700mm barrel with a Superior liner.....Will be testing the 380mm barrel next then will go through .25 and .30 just to see how things go with some heavier NSA slugs as well as the standard 23.95, 33.95 .25 pellets and 44.75, 50.15 .30 pellets.
No idea why I built this as it has more power than I will ever need for my purposes but hey at least I can say I know what an 18 grain pellet going 1300 feet per second sounds like hitting a stack of plywood!!
