I'm trying to decide between the two Criterion 300 win mag chamber offerings. I talked to Jim today, and found out the Match 300wm has .165" more freebore than the standard 300wm chamber.

I need just a little bit of info from folks already loading for a CBI in 300wm to help make my decision.

What over all length(COAL) to the lands are you getting with your CBI barrel? What bullet are you using? Which chambering do you have?

Thanks in advance.
