Get the Ruger 10/22. Don't use the included scope mount-buy a Weaver rail from someone like Midway, and use better glass than the usual style of .22 scope. Brownell makes a reasonable one; there are many others. The 10/22 is the small-block Chevy of rifles. Everbody makes accessories for every part of it-stocks, barrels, trigger kits. etc. There are even a few kits around to convert it to a .17 HMR.
Using the .22 for game at 150 yards is extremely sketchy. Bullet drop at 100 yards is 6", so obviously 150 is much worse, and that's not even considering delivered energy to the game.
As to reliability, I bought my first 10/22 in 1966, when they first came out. (It was $54.50
) It's still shooting. I even clean it once in a while.
