I sent a single shot 308 into Rossi to be repaired about 7 months ago,and yesterday I was told they would be replacing it ,and they are allowing me $272,but I have to choose from Rossi's web sight. They have little to choose from in the price range,so I am thinking about a 22 mag semi automatic rifle for $262,even though I see them selling on other sights for about$40 less. I can get a bolt 22 mag,but they don't cost as much,and I would like to get as close to the $272 they are offering me..My question is how much,if any energy is robbed by the action of the semi auto ,when compared to the bolt..I know it is probably a dumb question,but I hate to give up too much velocity on a 22 mag.
