Why do you think you need to neck turn your brass?

It seems to me that the major advantage of neck turning occurs in the situation where you have a chamber that has an intentionally "tight" neck, into which standard cases won't fit.

Then you turn down the outer diameter of the custom case until it just fits (maybe .002 total clearance) and you have a neck that is going to sit rock solid in there, reducing any angular difference from one fired shot to another -- because all the cases are fitting so snugly.

At the same time, you want the cases to be very snug also.
(This is for BOLT action rifles, not semis!)

There may be some advantage to uniforming the neck when you don't have a tight chamber, but it is probably a lot less.....

I neck turn my 6PPC to fit its custom chamber, but I don't do anything with my .223 standard chamber.

hope that helps,

"what is a good case neck width for remington brass?"

Th e Forster HOT-100 is a very good hand turner but I don't know what you're addressing: What width? And it matters a lot what you expect or hope to accomplish. ??

Pat,

Assuming you're not shooting a tight necked custom rifle, here is what I do. Adjust your neck turner so that you are only cleaning up about 50% to 80% of your necks. What you are doing is reducing the amount of variation in the thickness of your necks, without reducing the neck wall thickness to any great degree.

The Forster Outside Neck Turner is designed to be used after the neck has been resized and expanded. My Lyman works in the same manner. I remove enough brass to get a full cut on all of the neck. The cut goes to the very edge of the shoulder. If you cut into the shoulder to deep, the case will become weak in that area and could separate. After neck turning , bushing dies work well, but you can notice an improvement using standard dies, less over working of the brass. Testing shows it pays to weight and sort brass by weight, using Rem or Win. Plus other Bench Rest prep. I shoot factory chambers, not tight necks.

sorry for being so vague with my opening comment, my daughter was fussy and i was trying to calm her down and type at the same time ha didnt work too well...
i have a savage 10fp, but the barrel is stock, the reason that i want to neck turn the outside of the neck is to make every one case as consistent as i can, i do not compete but i do like really little groups.
with my loads now i can get groups down to .225" (best 4 out of 5 shot groups) and from what a lot of you guys on here said was this is one of the best ways to get a little more accuracy out of the rifle, short of buying a custom barrel (i will in time but i want to et my moneys worth out of the stock one first).
also i am using brass that i bought as virgin as well as remington factory loads that one of my buddy bought that he shot out of my rifle and i noticed that the factory loads brass have tiny dimples or crimp marks at the mouth of the case, id like to be able to turn those off or at lest trim all the brass so i know the case diameter is the same with all my brass
thanks
Pat
