Sorry I haven't responded to anyone, but for some reason the forum isn't sending me notifications of responses.

Thank you all for your input thus far!! There's a lot of good info above.

I spoke to Krieger (no eta on Savage pre-fits being produced, but has been mentioned), All things considered Bartlein is out of my wheel house. I'm sure they're great barrels, but for little ol me that doesn't compete etc it's not for me.
I've spoke to NSS as well and I'm leaning towards going that route. Might have to flip a coin between the Criterion and Shilen.
