Glockguy40 - I have been thinking of the same thing however I wanted a base line on what kind of accurracy I had already...
69 SMK
Once fired surp brass - cleaned, deprimed, swaged, FL resized, primed (Fed Match), and 23.5 grn H335
CMMG non ramped upper with a standard (cheap assed) DPMS barrel with standard M4gy HGs. The upper had approx 200 rounds through it.
ACOG with a doh_nut
Not exactly a group shooting combo to say the least.....
5 round groups were 1/2 MOA at 100 and 200
I would like to shoot this out to 600 but to be fair I think I should swap out the scope in order to get a better idea of what the accuracy is as the ACOG is not exactly the best for group shooting.
In the end, I like the idea of a trick barrel - but I am concentrating on loads at this point. I can only imagine what kind of 100 yrd groups I could get with a 3-9 and proper case prep on new brass.
Good luck
ps - I like the Pac Nor
