I thought I seen somewhere that If I have a H&R model 58 with a shotgun barrel that I can not replace the barrel with a rifled barrel. I am not sure that this was the guns original barrel anyways as it is a 34 year old gun and I just got it given to me today from a good friend. I want to know all the barrels I could put on this gun I would love to get a 30 30 or 22 hornet, Also Where can I find other barrels to buy? What other accessories are avalable for this gun and where is the place to get these accessories? Also what is the Talo squire about? is it more valuable than the normal model 58?
