308 neck turning question

[cfrazier77]

I have a question about neck turning 308 brass for my Savage FT/R. I want to neck turn so I can upgrade to a Redding bushing neck die and not have to sort brass. My question come from my using different brands of brass. If I turned the necks only just enough to make each brand the same size I would have 3 different sizes. WW .0125, Rem .0135, and Lapua .0145. So, would it be better to turn them all to .0125 and not have to adjust my neck turner and only have to buy one bushing or should I do all three sizes and get 3 bushings? I am trying to balance accuracy and efficiency at the same time.

Thanks in advance!!!!

Im going to ask some more questions about your question.

Does all manufactures use the same metalugic combination to make there brass? Are some brands softer than other brands? If they do and are, will they respond the same to resizing? Will the number of times fired affect the Neck tension as the brass work Hardin's?

Can the words speed & effenciency coincide with the word neckturning?

My opinion ( and its worth about as much as a 1 cent gumdrop) is to keep with one brand of brass or seperate into your three groups and shoot them that way. In a factory chamber I would not even bother with neck turning at all. More work and you could make it worse if you have never done it before. Of course if that happens then you can buy all new brass and it would all be the same brand.... See problem solved at twice the expense and work.

Sometimes it seems like you just cant win. Like argueing with the wife.

Good Luck Sir

cfrazier77: I also use all 3 of the brands of brass that you mention, for my Tikka 308, and find the neck walls to coincide with your measurements. But, for my factory chamber, I do not neck turn any of the brass, but do use a different sized bushing for each brand of brass, each bushing being the recommended .002" smaller than the loaded neck diameter. Rather than a light clean-up cut, I measure the neck walls, and any that vary (never with the Lapua) by more than .0015", are not used for anything other than basic sight-in, first round fouling, and the most "casual" type close range shooting-- nothing serious. I save my neck turning requirements for the tight, fitted necks only.

IMO, the simple solution would be to standardize on *one* kind of brass for that gun, and set your neck turner accordingly.

When using Lapua brass in my 12 F/TR I set my K&M turner to take the necks to about 0.0141" - that just happens to be where it comes out at when I adjust the cut for about 90% clean-up. I'm not going for a specific neck thickness as the chamber is not a tight-neck or fitted-neck one, but I do want those necks fairly consistent across all the cases.

Other people achieve similar results with Winchester, either by turning to a desired thickness or by simply buying bulk and then culling by neck-thickness variation. By the time thats all said and done, though, I think neck turning is quicker/easier.

YMMV,
