Tacklebury, thanks for the reply, but I'm not using a Rossi barrel, I'm starting with a blank and making the lug. I'm just wondering if the smaller frame of the youth combo will hold up to the 357. I'm doing the same with my Handi since they won't fit a rifle barrel to my 1997 mfg. frame, but with a scratch made stubb to avoid welding the lug to the barrel.
