Pellet fit

[Mike95]

I am now shooting a Webley Longbow and Gamo 440 in .22, using RWS superdomes and Hobby. The Webley is a very tight fit with the pellets fitting straight into the rifling. The force needed from the thumb(nail) often marks the seat of the pellet, I notice. The Gamo has a smooth bore pellet "seat" into which the pellet is put, before the rifling starts. The fit is quite loose and I use a pellet "seater" (free with Airgunner) to make a positive fit. The Webley is more accurate than the Gamo and I wonder if I should be using some other pellet in the Gamo.? Clearly the two manufacturers have differing ideas about pellet fit. I have seen reference to 5.51 and 5.52 size pellets, presumably slightly oversize.

5.52 tend to be the standard for JSB derivatives (Daystate/AA Fields etc).
5.51 and 5.53 are available for barrels that prefer them.
There's no easy way to test what brand/size is best for your gun other than to buy and try. Pellpax sell trial packs if you're having real problems. If the skirts get light damage as you put them in it's highly likely to make no difference to their performance as they get distorted to the barrel by the blast of air when you fire.

Edit.....Gamo have their own brand and I was highly surprised when I found I could group their heavies to an inch at 40Yds with a borrowed Gamo break barrel.

My Sidewinder (basically a Venom Longbow) loves AA Field 5.52s.
