I would be interested in hearing from anyone who has chronographed loads with two rifles of the same caliber, one having a micro groove barrel and the other conventional rifling.
We have been working with a Winchester M-94AE and a Marlin 336, both in .30-30AI. The Micro groove barrel seems to be faster, but has higher extreme spreads. There does not appear to be a difference in accuracy between the two barrels.
Two barrels do not make a rule so I would like to hear of other experiances.
