Don.
Carolyn don't handle my rifles to often maybe just to help get up on line she will hold it.
I don't know what this rifle will weigh with the .22 barrel on it with the scope. It handles a lot better with the tang sights then with the scope. I Don't remember what the length of pull is I think John said it was 13.5" but don't hold me to this.
I haven't shot much since I got this rifle with my time being tied up going to the clinic three times a week getting me back in shape again and it just seems like the cold is really biting me now that I just cant keep my shooting where it should be, so I been spending my time in the mole den casting and cutting wads for next season.
If you do decide on this project with the .22 barrel I think I would just order a complete rifle the way you want it. Cost wise it will not be that much more.
