I got a brand new Rossi 22-250 Heavy barrel about a month ago and fired it for the first time last week. The first three rounds fired it was hard to open the action. the fourth and last round the action opened upon firing. Obviously something is wrong with the gun and I'm just wondering since I am new to Rossi's could this problem be caused by a loose or improperly fitted barrel? I plan to return it to the store where purchased this weekend for their gunsmith to look at but I'm wondering if he wont just end up sending it off to Rossi. If it is a loose barrel it can only be fixed by replacing the barrel correct? If so how long does it take for Rossi to do this type of work? Any info would be greatly appreciated. Thanks
