As Graybeard says "i don't give legal advice" but here is some.......don't believe anything I say in THIS post.
Ihave Rossi, .308, 30.06 matched, and 270. Ok, riddle me this one. All have same head correct? Interchanging these barrels to frames "should work ok" and I have personally played with my digits and arms and eyes in doing so...270 on .308 receiver. That being said I have (believe this part) NEVER swapped an other barrels. The 20 gauge doesnot go on the 270...the 12 not on the 308 etc. I will NOT change anything to the .223.
Maybe I am all wet and an idiot (has actually been proven before) but if same head diameter and thickness then only difference is in tolerance on closed shoulder correct? If a tight lock up is achieved, I mean tight lock up. How is this putting any exces danger?
You may delete if too "out there" and flipant in responce......I se this as shooting someone elses reloads. DANGER is expected.
.22 on 30.06?
I doubt it ......and don't have a .22 barreled rossi.....yet. That .410, .22 combo is screamin for me to buy it and leave it permanent at the shck for a fun toy.
