I've been out for a few days and just read all the posts. Thanks for your comments.

It looks like I'm just going to stick with shooting Interlocks. I can load them down to dink with, then crank them up for game. They'll cover everything I'm doing for now. Too bad Hornady doesn't make a 120-grain Interlock. It might compete with the NBT for performance.

Ingwe, you don't have to worry about the IS being fed either Sierras or plastic tipped bullets (although I did have to do an exorcism on it when I got it since it looked like a few plastic tips may have gone down the pipe). I have a lifetime supply of 154-grain Interlocks, 160-grain Partitions, 160-grain Deep Curls, and 160-grain Grand Slams...each! There's some weird pattern developing there.

"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
