While I admit that lever actions are not tackdrivers, it is because of the entire package being designed for hunting, not target shooting. Further, I would add that the lever action was designed for large game. For fun, offer to shoot offhand against a friend with one of the supershort supermagnums in a lightweight rifle, like the Remington Model 7. If he has a multipower scope, the odds will be even more in your favor. I once had a customer shoot a Model 1873 Springfield against another customer's Winchester model 70 in .270, with a scope. I had loaded for both guns and knew that both loads were accurate. After the seventh shot at an oil can at 75 yards, the Winchester shooter got mad and left. The Springfield had made about 5 hits, and threw dirt on the can with the other two shots. The Model 70, offhand, could not hold a candle to the old gun. Now, for a final shot, it is not hard to get a lever action to shoot 3 inches at 50 yards, but a bolt action that will shoot into an inch at one hundred yards, will not shoot 3 inches at 300 yards. It is, therefore, easier to shoot game humanely with a lever action at 50 yards, than with a scoped bolt action at 300 yards. Differences in range estimation, wind, etc., will cause the groups to open up so that it will be unlikely for a shooter shooting at 300 yards will collect game, even with all the bells and whistles, than a lever action shooter at fifty yards.
Anyway, don't feel like you are at a disadvantage hunting with a lever action. Any gun, after all, is just a tool. Your hunting success with depend on your skill, no matter what weapon you happen to use.
