0.30" pellets in a 0.303" barrel?

At times, one needs to shall we say...."work out some frustrations" in a productive manor.

Can try the vise if you wish.

I had been told that the length of barrel I had came from a 0.303 rifle but now I'm not so sure.



I slugged it with a 0.308" lead bullet and it came out with a 0.300" diameter, exactly the same as the 0.30" JSBs out of the tin.

Sounds to me like the pellet would be a good match for the barrel, or is something tighter preferred?

Where are you measuring the diameter on the slug you pushed through?.... across the bumps (groove diameter) or across the hollows (land diameter)…. Either way, by the marks on that pellet it will probably shoot fine.... The barrel is not from a .303 British, that's for sure....

0.300" on the grooves, 0.290" on the lands.

A small legal aside, are non-restricted air rifles still subject to the 18.5" minimum barrel length?

[rsterne]

That is the same groove, and smaller on the lands, than a TJ's (0.294" lands)….

Unless they came that way.... I have no idea what rules apply if you "build your own" in Canada.... When the registry was around I used to register my builds.... Now I just do the obvious things, no bullpups, no silencers, and I haven't built anything over 500 fps and shorter than 18", or over 500 that started life as a pistol....

Sounds fair.  The barrel is just over 12 inches, perhaps a good starting point for a sub 500 fps semi-auto pistol...
