Can someone explain the advantage or disadvantage of a 3 groove barrel? I am considering a 6.5-284 and don't want to overlook a possible major item.

Thanks,
Rick

I havent used a 3 groove yet I think I herd where S1 is using some 3 grooves. I would call Dan Lilja and talk to hem or email Dan http://www.riflebarrels.com/ . My 6.5/284 is a Krieger 1 in 8.5 twist 28".

In two 30 cal cartridges, 7.62 NATO, and the 30 Wolf, The Lilja three grooves tested superior in 3 areas, Accuracy, Velocity, and Throat Life. The Krieger 4 grooves were close in accuracy, and velocity, not close in throat life. The Hart and Schnieder and Obermier were also close in accuracy. The Black Stars finished last in every catagory but throat life, and were not even close in the accuracy department.

Dana Cambell, a gunsmith up here had done alot of testing with 30/378wbys using 3 groove barrels and found best results with them.

My .22-250 has a 3 groove Pac-Nor 1:8 twist that is proving to be a good choice in accuracy and throat life. My 6.5-284 also has one identical to my .22-250 except for bore size, obviously. Its too early to tell with this one, but I'm pretty happy with it so far.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
