Neck Turning...

[DoubleGobble00]

I want to improve on my accuracy with my 6.5x47 lapua and wanted to know if neck turning would help. If so, what is a good neck turning tool to buy that I can use by hand. Thanks...

Neck turning is one way to improve neck tension consistency but there are also lots of match winners using no-turn chambers. If you decide to turn your necks, the K&M neck turner with a carbide pilot to remove the donut is hard to beat.

Unless you have a tight chamber to which you are fitting the brass, turning will not return much benefit, especially with good brass.

+ 1 WITH WINCHESTER69 BUT IF YOU ARE BOUND TO TURN NECKS ANYWAY A SLIGHT CLEAN UP OF ABOUT .001 IS ALL YOU NEED TO REMOVE AND THE K & M OR SINCLAIR TOOL WILL WORK WELL FOR YOU.

Thanks for the help and the information. My gun is a hybrid.. Savage Varmint action in HS precision stock with Shilen barrel. So it does not have a real tight neck to my knowledge. I was just thinking about upgrading my reloading tools and not sure what to get to improve my accuracy.

Ordered my new 6AI barrel with a minimum 6mm Rem SAAMI chamber neck. Have turned the necks on 50 fireformed cases with a Sinclair tool, about 50%, just enough to take off the high spot. Left another 50 cases unturned. All Win brass. To be honest, the unturned cases are averaging 1/4 inch tighter groups at 300 metres. This would seem to coincide with 'Winchester69`s' statement.

I believe I'll run against the grain on this one. I believe that turning the necks for consistancy is very benificial in any chamber when combined with proper anealing and brass prep. Neck tention consistancy = accuracy and having the ability to count on it shot after shot. This is a non issue however if you don't take the time to sort your brass by weight.

My 2 cents

Scout... Thats what I was thinking. I never thought about a tight neck chamber. I was strictly thinking about neck tension and was not sure if it would help. I assume neck turning is something you only do one time for the inside and outside of the neck.

What does sorting your brass by weight do with neck thicknesses? I'm just curious.. Not second guessing you.

Sorting your brass by weight is just another thing you can do to help ensure consistant pressures. Just as most case necks vary in thickness from the factory, you also have the rest of the case to think about- head, webbing, walls, shoulder that take up internal volume. The preveously mentioned you can do nothing about, so you sort your cases according to weight and group them together in order to achieve the tightest tollerence for case volume., consistency ) I group mine into -.5,+.5 of a target weight. Anything in between still falls into a 1 grain varience for the lot.

When prepping brass for a no-turn chamber you only need to turn your neck once, after fire forming. The difference when using a tight neck chamber is that virgin loaded brass wont fit untill it is turned to meet chamber spec's for fire forming, then a light cleanup is done if needed after.

Hope this helped explain it
