2 good reasons to turn case necks.to make them concentric,or to make them small enough .it isnt a majic wand.if you dont need it,dont.

There is another thread in the forum concerning this, I believe.

It's pretty hard to make concentric rounds with uneven case enecks. However ,it is one of those things that only contribute to minutia in accuracy , but when added all together helps.
If you do not have a means to measure concentricty of your lodded rounds, turning case necks probably isn't going to help you.

I only turn case necks for one rifle..This is a match grade rifle in 7x57mm with tight dimensions.
You have to have a ball mic and also know your chamber dimensions..
Just turning necks on cases for every rifle,I see no benefit in.You are taking brass away and shortening brass life especially if fl resizing..
Is it worth it??In my 7x57,I have turned in .18" groups at 100 yards..In my Remington 700 30-06 I hunt deer or hogs or antelope with..Nope..

no i would not turn necks unless it is a tight neck chamber. I used to shoot bench rest years ago and shot the typical gun 6 ppc .262 neck. This was a popular neck and under size of a standard ppc. So with the custom bullet ( berger, euber, hollister ) you was shooting the neck had to be .261 leaving 1/2 .000 on each side for bullet to release in laymens term. If you was not precise it could be very dangerous and some gunsmiths would not chamber a tight neck for someone not knowing what they was doing. So on your average hunting rifle with a factory chamber shooting regular bullets sierra, etc., turning necks would be almost like making a mess out of a mess. If it is done properly turning necks is a real pita. Stick with the other case preps. for tuning a load such as, flash hole, case length, seating deph, etc.

I agree with mike33. A few years ago I turned every case in my garage during a particularly cold winter. My groups went to hell and my standard deviations went from single digits and low teens to the mid 50s.
I was shooting service rifles (AR15s, M1s & 1903s) and standard chambered bolt guns.
If your gun does not have a tight chamber, neck turning is actually harmful to accuracy.

Not only that but over the counter bullets are good but very sloppy when it comes to this practice of what it is intended. Custom bullets as i mentioned are next thing to perfect on this aspect. Again not being negative on sierra, etc., but will not compare to customs that why these few individuals make custom bullets. Glad to see some one on line, made a post last night and no responce.

Mike, you`ll see here that some posts get more attention than others.That is just the nature of a board like this.I myself tend to post more in regards to sub moa comments and particular such things like this.Some posts I won`t comment on as many folks don`t`.If I don`t have relative input on a post or question,I read and learn , and don`t post..Most of the fellas here are like that..

Thats fine , just feeling my way around. I basicly like to learn and see what other people who share my interest is doing. I never post unless i have experience so i know what im talking about. Would never like to give bad advise just to make posts.

I am similar to Mike, I just read and learn, however on some subject I do have an opinion from my experience and this is one. I have a 6PPC 264 tight neck for which I have to turn the necks. I turn them to .009 which when using a .243 bullet gives me .003 tolerance, and it is a tack driver usually in the 2's I am hoping for 1,s if I can do my part. I also have a 6MMBR which shoots the same dia. bullet. It is a Cooper Mod 22. It shoots MOA consistently. Since I had the equipment for the PPC, I decided to "Clean up" the necks on the BR cases just removing enough to have the die touch about 80%-90% of the diameter. That MOA was cut in half and I don't seem to have near the fliers as I use to. I believe the neck tension is more concentric there for making for a cleaner bullet release in the chamber when the neck thickness is the same or closer that factory cases. BTW all my cases are Lapua.
This is a great forum! There are many knowledgeable shooters and loaders here, thank you for your input, although I do not post much I have learned much from this forum.

sounds like you have a sweet rig in that 6Palmisano..In your case I can absolutely see neck turning.I am considering to do it in my 244 Rem but I haven`t made my mind up.If I could ring just a smidgen more accuracy from it I could get it a solid .2-.3 rifle.The rifle shoots better than I do most any day but now and then I am in the groove with it and she can make some mighty tight groups..
glad all of you fellas enjoy the site.We are working constantly to improve it and make it a place where everyone feels welcome to learn and share their knowledge with new and old handloaders alike..

Depends on the rifle, for me if it shoots good I do it and make it shoot better. I did a test on a Savage of mine and it closed up groups 1/4" off the bat. Still playing so not done yet. Little brothers 243 seems like it may need some work with the Nosler brass he's got now. New rifle shooting good and unless it's a max load you can't push a bullet in the fired case without a good deal of pressure. Max load round is just loose enough to push bullet in without feeling resistance. Sounds like a candidate to me. I've been using a Forester but just bought the newest Sinclair model and the case holder. Will be turning a lot more now. Here's a link to the post. I might add the premium brass are pretty darn good without it. I just do it on the cheap brass to make it better.
