Possible???

[Guest]

I have a 12” .25 AF barrel that I’m not using and it got me thinking. Could I bore it out to 8mm and install a 22 LR barrel liner in it to shoot 22LR projectiles? Has anyone done this? The liner is only $35 from brownells. Just a thought. I think my TalonP could sling those slugs pretty good.

I would think that it would be better at stabilizing them than a slow twist pellet barrel. Especially if you shot 35-45 grain slugs in it.

I think the bigger cost factor will be machining. A raw 22lr barrel from Green Mountain is around $45 before shipping. So boring out a .25 AG barrel might cost more than having a barrel cut to size and machined to fit the action, of course with the new barrel, you need to have new frame bushings made too. Of course, this way you'd still have the .25 barrel...

It was several years ago that I had similar thoughts. I honestly forget why I gave up on this but all my AF stuff is gone now. 

There was an airgunner making .257 (?) kits with larger valves for the AF line. I forget who that was but you should search the Talon forum if you are serious about trying this.

.22 LR bullets are heeled (base smaller than diameter) to fit inside the case. I don't know any source for such bullets. Standard .224 bullets for a WMR or .22 centerfire are too large for a .22 LR bore. It might work in a .224 barrel with lead (unjacketed) .224 bullets.

so my answer is maybe but my question is why

you could sell the barrel and get a .22 barrel and if you needed some heavy pellets these might do the job or some other brand

the bottom line is the why, with enough money you can do anything

I was just curious if anyone has done this. I’ve heard of a few guys adding 22lr barrels to their airguns. They just pulled the bullets from the 22lr casings and used those. I did some measurements, which I should have done before I posted the question, and realized the breech end of the AF barrel is too thin to accommodate the barrel liner. Now this has me thinking about getting a .17 hmr machines down to install.
