Sorry to be a pain in the a**, but I'm actually researching my next rifle instead of buying on impulse. I've decided that I want a sub $350 (sub $300 even better) rimfire rifle that will hit the staples on a target at 25 yards, a golf ball at 50, and a tennis ball (multiple times) at 100. Should I stay with 22LR or go with 17HMR? The 17 is supposed to have a flatter trajectory and is a higher velocity round, but will a crosswind give a problem with a bullet that only weighs 17 or 18 grains? Are peep sights effective at 100 yards, or is scoped better? Here are a few that I'm looking at. http://www.remington.com/products/firearms/premier_dealer_exclusives/model_597_LSS.asp http://www.savagearms.com/93R17gvxp.htm http://www.savagearms.com/markiifvxp.htm http://www.savagearms.com/markiifvt.htm Any other reccomendations?
