them readings are fanstasic compare the one I got with mine at 2400 fill. I was using 14,15 & 18g pellets but I didnt record the stock setting. My highest reading was 635 with an avg of 620fps for 24 shots. guess I'm gonna have to test it again, its been awhile.

JSB Exact RS.... the tin said 13.5grain

Nothing changes on the gun (except the stock and shroud...)

lighter pellets produce higher speed. when I did my test, I didnt have any light ones to test, I went from 14 ,15 and 18. the heaveier the pellet the lower the fps, but speed over weight equals modre energy, I think that's how it goes.

now we need the crosman SSP's in .22

 

But I do need to go get some more of the JSB exacts. I'm buring thru this tin pretty quick. IIRC Chairgun says  just under 15 FPE ......

I tried these in my rifle and at 1150fps they are not accurate. I know the speed had something to do with the accuracy but I did notice too that a bunch of the tips were not pointed and off center, the pointed ones that had their tips centered weren't to bad. I might have received a bad batch but about 75% of the tin was bad.

Here's a pic

Destroyers now, if I could find some in .22 might be worth a look.....
