Does anyone here have any accurate data on stock R9 FPE or velocities at 50 with popular pellet brands ..Jsb,H&N..Etc ...14.66 to 15.89 grn...thanks in advance
.22 R9 FPE at 50
- Thread starter Ace1969
- Start date
15.89 needs to zip along at 1,190fps to make 50fpe. Is that what you are asking? My apologies if I didn't have a clue. Bill and Addi

Beeman R9 max stock velocity is 740fps(they use really lightweight pellets for advertising most max fps).
Given you are shooting 14.3gr Crosman Hollowpoint at say 680fps(to compensate for a slightly heavier pellet); right at the muzzle would give you: 14.69 ft-lbs.*roughly
So let that little puppy zing for 50 yards and you still have right around 9 ft-lbs.

Gotcha. If you don't have a chronograph, down load Chairgun and you will be able to get that info. Ofcourse you'll need to know muzzle velocity. If unknown, use the mv from factory specs. The fpe will be very close between the two weights. Bill and Addi

I know with Jsb Hades 15.89 are in the 660's at the muzzle and 605ish at 25 yards with a close .028 B.C. give or take but, I question if chairgun accurately can calculate the FPS from 25 yards to 50 accurately? Chairgun says its 10.6 fpe ...this calculation at 50 is reliant on the velocity at 25 yards at 604.Can this be trusted?

close enough i reckon
FWIW, My HW95L .22 with an ARH kit with Vortek seal runs 720 FPS on average. Chairgun chart which closely matches my rifle actuals. Rifle is accurate for my plinking and sometimes I can keep a 5 shot group within an inch or better at 25 yards. I use H&N FTT 14.66 gr 5.53 mm pellets.

I guess any thing or guns different at any time or place ? From straight shoot our take.
So 7-10 +/-

Deerstalker,would you be able to upload a higher resolution image of your data here ..I can't seem to read the numbers as they are blurry and the Imgur app required to view isn't working for me ..lol ...thanksFWIW, My HW95L .22 with an ARH kit with Vortek seal runs 720 FPS on average.

Gets me is say 7-10 at 50y but i shoot a thicker been can at 100y and still put a hole through it. So if i lost that much at 50y seems id pertty much have nothing at 100. Should it not be about 0 enegry by then ?
