Does any one know what the bore dia. is for a .25 cal? Thanks Craig

For what?.... an airgun barrel, like used on the MRod, or a PB barrel such as a .257?.... They are different enough that they do not interchange.... You can only shoot pellets, or bullets designed for the smaller diameter, in a 0.250" airgun barrel.... and you can only shoot bullets in a .257" barrel, pellets are too loose.... LW uses something in between, at about 0.254" and then less at the choke.... designed for pellets only....

I have one on loan that is 25 caliber and I made slugs. 250 and they were way too tight - could barely push them in. .248 loaded nice but we're not accurate. I made them .249 which were pretty tight but more accurate than .248.
That is not to say another barrel from them would not be slightly more loose than this one. This one probably needs .2485 but I don't have that sizer, only .248 and .249.

Bob,
I'm sorry. An airgun barrel, used on my MRod. Craig

I would not mind knowing how much choke they usually have...
