You've never shot someone else's gun? (Like, by asking people at just about ANY RANGE?)
You've never gone to a range where they rent guns? (Like, almost EVERY RANGE owned by a gun shop?)
"Try before you buy" is more common with guns than it is with cars.
Please.
Only if you live somewhere where you can do that, at the same time as having the money to do that, at the same time as having the time to do that.
So here's a factoid: I have had one opportunity to go to a real rifle range in my life. I shot a DCM round, with an SKS that had trouble hitting the TARGET at 200 yards. I later found out why, by shooting it at a sheet of paper at about 50 feet, the resulting hole was a perfect profile of a boat-tail bullet. I think this is what in Vietnam was called "tumbling".
I have a .22 with which I can prune shrubs, and I've done quite a bit of archery. I know where I aim, so I do in fact want a rifle that is reasonably accurate without the sarcasm.
Some day I hope to have the time, money and opportunity all that the same time.
