I did get a very tight group of 3 shots by pressing the pellets in 6mm or so but the next two were well off.  I thought I'd cracked it but apparently not.

So next I pushed a pellet the full length of the bore with a piece of aluminium welding wire to see if I could feel any tight spots and found that the it's choked - which I wasn't expecting.  Otherwise, the pellet slides freely after the initial set.

My question is, will removing the choke help improve accuracy at all, and if so, how do I go about it?


you may find slightly larger pellet head size works well if the pellet feels too free (sloppy) after the initial length.. something like 4.53 headsize ratehr than 4.52 may be enough.
Or a thin skirted pellet like JSB should blow out into the rifling to engage

regarding the choke, only was I can see to remove it is not exactly reversible - chop it off and recrown..
