Ultra at over 18fpe…
You may be able to do it… The Ultra does have a hammer spring adjustment behind the endcap… but……
my experience with it is that if set for anything other than factory specs, the gun tends to be quite erratic velocity-wise.
Besides… with that tiny tank on the Ultra, if you bumped up the power much, your shot count will plummet. You’re only getting 20 or so shots at 18fpe… bump that up to 24fpe for example and your shot count will be roughly half that. Just not worth it. Have him enjoy the gun for what it is or trade it in.
Sorry the ultra is what he’s looking at
what bsa rifle r we talking about mate there,s a few multi shots about now
the super 10/ the ultra and the t10
Some of the BSA pcp’s have a preload adjustment screw at the back of the action.You will have remove it from the stock to see it.
