The Bartlein is in my top two for barrel choices. Tied with Krieger.
There is only so much powder the 30 caliber is ever going to use no matter how big the case is or how long the barrel is. The 300RUM is right there. The 30-378 of over the line for me. I wouldn't suggest getting complicated with this one. The 300RUM holds it's own just fine. 3200fps with 230's in the longer barrels. That really should do it. Then again if you want something different the Tomahawk certainly is different.
I don't really have any barrel favorites, but other than that I'm pretty much in line with the above. There is very little room to improve the 300 RUM cartridge and if I was to do so, I would go with a 30/338 LM Imp. I see only one powder being useful in the larger case and that is RL33.
To the OP, sounds like you got a good barrel there. It should stabilize everything up to the 230 Hybrid very well and seeing that you are in CO it should stabilize the 230 well also. Go for it.
