Barrel diameter input needed.
I’m going to start swaging heavy pellets in .177 .22 and .25.
I’d like to try to make them suitable for use in Air Force guns as well as others.
The groove diameter is what I’m after and the make of the barrel would help as well.
So if you have slugged your barrel and know the diameter I would greatly appreciate the info.
Good possibility I can supply you guys with a heavy pellet when I get this all sorted out.
Thanks for your time.

Here is what I have so far.
.22
Crosman 2240
.2205 grove
.218 lands
Air Arms .
.219 Groove.
.215 lands.
25
Walther
.255 groove.
.2501 lands.
Shark
.252 groove
.246 lands.
As you can see the make of the barrel matters so if I can get some input on Air Force barrels and a few more Walthers I might be able to make this work.
No wonder some guns are pellet picky huh.
