hi, iv just bought a new s410f super light, with walnut thumbhole stock and on geting it home i fired a few shots through the chrono with AA field diablo .22 and i was disapointed to find it making 10.2lbs, surley this isnt normal? i was expecting at least 11+ for the price i paid, is there any way to up the power a little without interfering with it too much?
thanks

you really need to put some pellets through it first to loosen things up before expecting high 10 / low 11 ftlb results .

put a couple of tins through it over Christmas and re-chrono then , THEN if its still low 10's it can be returned to the shop you bought it from or worked on by yourself if you want .

As above you need to bed the gun in and get this to settle down

good luck

Mine took a good 3 months of almost daily use before it bedded in and settled at 11.2ft/lb
That bedding in process also makes the action a lot smoother and easier to cycle, so give it some pellets

Hi, buy some cheap pellets and use those, rather than expensive AAF, to run it in. You should find that the power comes up after a couple of tins, the temp can affect things as well, not just the gun but the chrono too. Once it is run in try different pellets as these can make a difference as well. My .22 Supalite loved JSB Express which at 14.35 grains gave it a noticably flatter trajectory than AAFs. It also liked JSB RS at 13.45 grains (Falcon Accuracy Plus are the same pellet). Best place I found for JSB pellets is Intershoot, free p&p.

Hi,

Also test it again at about 130-140 bar (the mid point of the sweet spot typically). Bet it makes more power here!

Thanks very much for all your advice. Got a couple of days off, so expecting to rattle through a couple tins anyway. Hope everyone has had a good Xmas!
