Looks like you found a winner!

Hope you have a lot of them. Sierra stopped making them few years ago. They always shot well for me in 06, 300WSM and 300WM. Great bullet! Bet Sierra dropped it for their 180TGK.

I wasn't aware they discontinued it, this is an old box that's been sitting around for a few years. I'm shooting through bullets that I've had sitting around awhile, then I'll start using mostly solids like hammer, Seneca and Cayuga etc. I bought this barrel years ago for a customer and then he changed his mind for an 8mm something. I chambered it for myself on a whim and it's shot everything I've put through it very well. Everybody needs a shorty .308!

I sold off couple boxes cause of that. Should have kept them though.

the 180 interlock should shoot as well or better. I seem to gravitate to them in my 30's over the heavier sierra pills. The 150 pro hunter has done very well for me in the past though. ~2700 fps from a 308 with a 180 is doing very well too.
