Ive been reloading to some degree since the late 80s. I have never neck turned brass before for any of my rifles.
I have a rifle in a varmint caliber that I really want to keep, but it seems to throw a flyer most groups.
I took 50 cases ( sorted in groups by weight ) and spent a good bit of cash on a PMA neck turning set up and used a cordless screw driver. I set up the tool to clean the necks up 90 percent on 3 cases. Then turned half the cases. I was amazed at the difference in the amount cleaned up on the cases and the case overall weights after turning allowed me to eliminate one of the sorted weights. These are 50 fireformed cases that were neck sized only. I will say there is no way I would do this without the screwdriver or some other powered set up.
I loaded ( weighed each charge ) 40 rounds... half in the unturned cases and half in the turned cases and shot some groups. The unturned produced flyers like always. The turned cases did not throw any flyers and the 5 shot groups stayed tighter.
Not a scientific test by any measure, but I'm going to turn the rest of the cases and the rifle is a keeper if the groups stay tight. I assume there is something to neck tension after all. Im not a competition shooter by any means, but the new confidence in the rifle was worth the cost of the set up and I will take a chance in my larger caliber rifles and some brass to see if I get similar results.
This is a bolt action rifle that is properly pillar bedded, free floating barrel and good aftermarket trigger.
