I keep some 15.9s around because none of my rifles will get the 18.13's into the 850-900 fps range. Thats my goal - to buy or put together a "normal" weight rifle (9 pounds or so) that launches the 18.13's in that 850 range, accurately. Think of it as a "light heavyweight".

There are plenty of reports of the Hatsan 125 & 135 exceeding 30 fpe, so even 900 (32 fpe) with an 18.13 should be doable. The 9 lbs goal might not be though....

My "best" .22 is a gas ram RWS 350. I haven't chrony'd it but it should produce 725 fps or so with those. Not quite what I'm looking for. Magnum complex....? Check!

The sound of pellets hitting the trap tells me that the 350 does well with the 15.9's, and that makes sense. It certainly has more pop than my Hatsan 95 which is 800 fps with a 14.3. I'm guessing 800 with the 15.9's for the 350. That puts it in the 22-23 fpe range and in a good velocity window to hold on to that energy.

As an aside, you don't read much about the NTEC guns but I like mine very much. It is very well made, has a fine trigger, shoots strong but isn't ridiculous to cock, and so far has been impressively accurate (at only 9 yards, but we will soon see what it can do at longer range)
I dont remember if your 3500 is a gas or coil spring gun, but either way it should be nearly identical to a 350. You might want to try some 15.9 JSBs in that rifle too.
