    Looking to volume load for squirrels. Only one possible tight nk - 22ppc.
    Brass:
    I have Palma and LC that I want to make into 6 BR, 6xc. Also some PMC 7.62x39 into 22 PPC as well as many 223 LC, IMI & 222 for Prac, VT and Duster - all 20s.
    What are the pros/cons of neck reaming as one of the steps while reducing the neck? If several nk turning passes are needed, I'm thinking reaming 2-3 thou can be done faster than nk turning. Of course take a few all the way through to prove the process.
    As far as what's available to me, I have a floor drill press......maybe a mill. MAYBE, if i can rent some time from the bait/gun shop guy out in my area of the stix.
    FWIW info. I'm a retired toolmaker but a novice case processor, precision reloader.
    Let'er fly guys

    I think most thoughts on reaming are it can still be off center. Outside turning will take the true high spots off.
    Ream if there is a bunch to remove, I myself would still turn the outside.
    Others can explain better.

    Turning may or may not make a mediocre shooter shoot better. I have had and seen it actually make it worse.

    Trueing up the neck wall thickness, making the neck thinner. When actually it needed to be thicker for that specific chamber, made end results worse. I then had to partial neck size and leave the neck towards the shoulder alone.
    That inturn made me neck size, then body size at times.

    Clear as mud?

    I capiche. If two turning ops were needed, say 308 to 22, would using a mandrel to knock off the high spots on final sizing be an option?
    That is to say, size it to 7mm, ream ( w or w/o expander ball, then take it on down to final cal then nk turn to whatever extent needed.

    Cutting outside of case necks is the only way for me. I ruined some pretty good 220 swift brass by reaming the necks. They went to the trash... Best of luck with your project.

    47W. What was your sequencing and at what stage reamed with ??? size reamer?

    i am not sure this is a good plan.
    case choices are not great for accuracy

    20 practical is the only reasonable if you have a large single lot of brass

    RS, you say case choices. My case choices include IMI, LC, Lapua, PMC.
    Not sure that I need better than .25- .4 moa for squirrels.
    Or do you mean chamberings? :)

    I turn my 6BR Lapua necks to 0.125" in one pass. It's been a while since I turned new cases but I think around 0.013" tk just cuts about 3/4 of the neck. If you don't have a tight neck your rifles may shoot small groups without turning. I would just do a light clean up turn leaving part of the neck un cut. They are not serious bench guns. I only shot one rifle for 40 years at GH.

    Last year I thought I wanted to do some volume shooting. Purchased a large lot of 308 match brass and LC Match brass. It took me a couple of sessions to realize I was doing my sequencing all wrong. I ordered small base sizing dies and processed the match brass as if it were for the 5.56 and .308. Size, trim, deburr, primer pockets, flash holes, etc. After the brass was processed, it was easier to take it in lots of 100 and make brass for different firearms. 260 Rem and 7-08 were easy from the 308. The 5.56 made up 300 whisper to 17 Rem. Much more consistent after processing the parent brass first and yes, actually took less time in the long run as I didn't have to re-do any of the processing like I did before. Nothing worse than having 100 17 Rem that wont chamber because of oversize base. Good luck.

    That definitely makes sense.
    I was on the coast, Chas & Beaufort, for 33 yrs before moving back to IN. Where be you?
