BSA Magnum .22 “Clipping” !

[Blackrider]

Guys, I have a boxed example of the above but the only problem is that one, in every five shots, the pellet appears to clip the muzzle and obviously shoots off in a distressing trajectory !
It does this with several different brands of .22 pellet. The rest of its operation appears be true and the general operation of the pistol appears to be fine.
Any idea of the cause and more importantly, the remedy ?
Many thanks.

Do a quick search on here as it’s been covered very, very recently. Troubledshooter has also kindly posted the strip guide.

Hmm, can’t find Ferret’s original post, but some answers referred to enlarging the hole through the plenum. Not a problem I’ve had on mine, but seems some .22s suffer with occasional clipping. No doubt some answers will be forthcoming.

I have covered this many times regarding the pellet jumping the gap from the end of the barrel to the exit hole of the pistol during recoil. Just open the exit hole very slightly to give the pellet more clear space. See link illustration of problem.

Sincere thanks for this, I’ll give it a go !
Would a small fine round sectioned file be the tool of choice ?

I use an electric dremel, but a round file will do the job, just increase the hole diameter slightly.

Many thanks Baz !

This evening I finally got round to sorting the plenum with a freshly purchased "round file" !
The pistol now shoots well but I'll now need to find out what pellet it likes. I gave JSB Jumbo Exacts a go as they happened to be handy but they seemed to to a wee bit slack in the barrel so something like H&N Field and Target Trophy 5.53 or 5.55 might work better, who knows ?

Exact and FTT may be a bit heavy for pistols, I'd try RWS Hobby, JSB RS, perhaps some of the lighter H&N wadcutters.

Thanks !
I'll try Hobby's, I also have a box of Defiant alloy pellets which may be OK !
