so I recently paid for a used competitor-pistol. It came with 4 barrels and I didn't realize at the time how rare they were

 

6.5 rem mag (not so bad)

 

22-250 ackley improved

 

22 rem br

 

.458 x2 american

 

They all sounded familiar at the time *shrug*

 

I'm told I can fire regular 22-250 out of the ackley barrel but how does it effect accuracy? Does it affect the barrel over time?

 

what is a .22 rem br? can I buy ammo for it? (I can't seem to find anything labeled that way)

 

.458x2 american I'm learning is rather rare. I don't reload yet, I would like to but I don't think I want to learn on a wildcat cartridge, it seems like it would be helpful to have a seen and fired a factory load for reference

LOL! You got yourself a real wildcat target gun! You've got barrels for designer cartridges, which are called wildcat. Some took off and now go by another name.

 

It's more commonly seen as 22 BR Rem which is Benchrest Remington. 22/250 Ackerly is 5.6 Varmenter and Hornady makes it. .458x2 American is a big bore round based off the .458 Win Mag and is easily made if you're a hand loader using Win Mag brass. I don't think any big companies are making it, but several boutique ammo makers do if you don't hand load.

 

EDIT: Reading your post more carefully, I see you don't reload yet. Well, great time to begin! Start with the 22 BR Rem, it's a terrific round!

Just curious did you get the gun from Bangers? If so, I think I saw that pistol there the other week.

Yes, you can, but I don't know anyone who makes factory ammo for the .22-250AI unless it's from a custom ammomaker. You can shoot regular .22-250 Remington rounds in your .22-250AI barrel and they will be fireformed to the correct chamber dimensions once fired. All you need then are .22-250AI dies with which to reload. Accuracy will be better with the reloaded .22-250AI rounds due to a better chamber fit. ALL Ackley wildcat cartridges are designed to be fired in their parent chamberings.
