Gary73 62 Posted August 29, 2016 Report Share Posted August 29, 2016 (edited) How consistent do you think my R10 should be? Rifle BSA R10 .177 Super carbine 6 weeks old but put a huma reg straight in. JSB Heavy pellets straight from the tin 10.34gr. BSA reg out Huma in with no power adjustment needed. x10 shots in fps Huma Reg 712 711 706 708 698* 713* 703 712 700 708 BSA Reg 710* 706 704* 707 708 710* 710* 710* 709 708 Any idea why the BSA reg if far more consistent. Both tested at 160bar and the same results have shown when the same test has been conducted 6 times. Edited August 29, 2016 by Gary73 Quote Link to post
ianm 2,594 Posted August 29, 2016 Report Share Posted August 29, 2016 I would of expected it to be 2/3 fps difference max with a Huma reg, i sent mine to John Bowkett for a blueprint and he fits his own reg in them, it's only a couple of fps variation. Quote Link to post
Gary73 62 Posted August 29, 2016 Author Report Share Posted August 29, 2016 Took the reg apart and cleaned it out really well and tightened everything up.. Results are better certainly good enough until it goes for its x-tune. Jsb exact heavys in fps straight from the tin. I am sure if I weighed then it would likely be single figures. 20 shots 180bar 706 702 712***** 710 707 705 708 701 703 712***** 701 708 706 700***** 710 710 703 705 706 707 12fps total spread and +/- 6fps 706fps avg 11.45avg 11.25min 11.64 max. Take out the 712's and 700 10fps spread and +/- 5fps Seems more stable and I doubt I would see much between 700fps and 712fps at 55 yards. -4.68" at 55 yards at 712fps and -4.9" at 55 yards. -4.79" drop at 706fps. Roll on the x-tune and will be interesting to revisit this after its return. Quote Link to post
Metalman2 45 Posted August 29, 2016 Report Share Posted August 29, 2016 A difference might show between regs if you filled over 200 bar, Quote Link to post
Gary73 62 Posted August 29, 2016 Author Report Share Posted August 29, 2016 True, I only fill to 200bar as I reckon on shots from that with less stress on the rifle etc. More than enough from a 200cc Buddy bottle to chase the vermin. Quote Link to post
Metalman2 45 Posted August 29, 2016 Report Share Posted August 29, 2016 It's a while since I had a standard R10, but the power used to be prone to "spike" before coming of the reg Quote Link to post
ianm 2,594 Posted August 29, 2016 Report Share Posted August 29, 2016 I always fill mine to at least 230bar .22 950 fps 32ftlbs. 1 Quote Link to post
Gary73 62 Posted August 29, 2016 Author Report Share Posted August 29, 2016 Very nice, but only 930fps Quote Link to post
Metalman2 45 Posted August 29, 2016 Report Share Posted August 29, 2016 I always fill mine to at least 230bar .22 950 fps 32ftlbs. How many shots would that yield, is that with 200cc bottle Quote Link to post
