At some point those lighter bullets (assuming they've got a lower B/C) will be going slower than the heavier ones, though with normal bullets that often happens past "normal" ranges, despite the higher muzzle velocity. The more I venture into stretching shots out, the more I am going to say "no" to your question.
That, and some states like WY have a minimum weight of a bullet for hunting. 60 grain minimum for .22 CFs, I presume to prevent the use of easy and cheap FMJs. It would be much easier for game wardens to check for FMJs than to check the bullet weights though...just another SMAFU in the political world.
I did not know that. I was going to take a model 70 22-250 to WY for pronghorn this year. It's 1-14" so I don't know if it will shoot 60's. Guess I'll try.
