so, I almost bought my first rifle- a marlin bolt action, with a thumb hole (i want to say the 917vt) but, as I was filling out the forms out, I found out it didn't use .22 lr, it used .17 hmr; from what i've heard, that's a superior round (flatter trajectory, higher velocity), however, it's more than twice the cost (per round), and that means I'll shoot less (maybe) but, it probably means I'll shoot /better/ since accuracy shooting isn't about throwing as much lead as possible down the range BUT it'll have more recoil (10 times as much?), and I'll probably break/bruise my eye socket on the first round bottom line- what's a better round to start off with? what round should I begin with that will provide the right mix of elements (fun, challenge, value, a gun that "grows" with my ability (that is, something where for a while the limits on range/accuracy are due to my skill, and not the gun's craftsmanship), etc) i guess with either one, I'd start at the 25 (50?) yd range, but for sure I'd start out with a scope (because i think they're neat), and in the standing position? (working to knealing, laying down, then bench) although, i guess the first thing i would do is sight in the scope? there's no break in period with rimfire rifles, right? can I achieve 1 minute of angle accuracy with <$450 invested in a rifle + scope + mounting equipment?
