Please may I reintroduce myself

Campbell

In late August 2020 I suffered a stroke (bleed on the brain) and my I had a rather protracted effort to get my FAC renewed. However, I am back!

Previous to my stroke, you folks gave me shed-loads of advice and, If I may, I would like to again ask you to help me.

My next accuracy reloading quest is neck turning, I have done it earlier and thought it a waste of time, but speaking to very accomplished shooters, it seems to be a worthwhile exercise.

I have the K&M kit. Please will you give me any advice.

Good to know you survived the stroke and made your way back, I wish you continued recovery and success!

I outside neck turned my last batch of Lapua brass which is now approaching end of life. I proved to myself the necks were more concentric after turning than before by profiling both the inside and outside neck diameters over the entire length of the necks. That's not surprising considering the process but, I like to verify what I'm doing has the expected result, especially when what I'm doing is irreversible. After shooting 35 or so pieces through 12 cycles, I have a pretty good idea where the cohort stands, on the target.

My next cohort I'll leave unturned, at the end of it's lifecycle I should have an idea if neck turning, for myself, is worth the effort or not.

What I believe to be true is that it's possible to turn too much off the necks, making them too thin. Having a decent tube micrometer is a way to avoid that. It's also possible to cut too deep into the shoulder, developing a way to cross-section a sample or two may indicate how far is enough, and how far is too much,

Welcome back!
 
Generally use your K&M kit by following their directions. Mainly trim the neck to start, by only triming it and taking the high spots out.
If this works well in your chamber, stick to it. I like to trim my case necks on a average of .012 to .013, which seems to work well with my chambers.
Experiment some with yours and see what helps with your reloads.

And Welcome back and continue with your health going up and better each day.

Howdy ! Welcome back, and glad to read your health is better.

As regards neck turning....

You may not have to do very much.... perhaps little more than a skim trim to remove
" orange peel " texture from the outside case necks ?

Neck turning is part of a one-two punch, the second part being neck sizing.
Reduce neck wall thickness a certain amount, and as a consequence; you'll likely have to make an adjustment to the amount of neck sizing you perform. The introduction of neck sizer dies, bushing NS dies and the like; were a helpful adjunct to the case prep sequence; especially when neck wall thickness was reduced.


With regards,

Do what I did ... sell your K&M Neck-Turner to someone else so that they can also figure out that neck-turning is a waste of time. I buy great brass (Lapua and Peterson), anneal with an AMP, use SAC bushings, and 21st Century mandrel prior to NeoLube and seating (with an AMP Press). Without neck turning, I'm getting less than 1/1000th in runout. My process is solid and it shows in my neck concentricity. I tested with neck-turning, and without, and got the same results ... without actually being slightly better. I get it if you're a nationally ranked top-tier competitor. But for me and my regional and local competitions, the "Neck-Turning PITA-Factor" far exceeded any advantage. IMHO - your mileage may vary.
 
Best wishes on your recovery and getting back into the sport.

I don't turn necks and never did because I am able to reach my goals without doing it and I hate adding any additional steps / equipment to the reloading process.

However, I am not a competitive benchrest shooter either so I will not disparage the process because I have no experience as to whether it is effective or not. In your case, if I was producing reloads that met my goals I wouldn't embark on this process.

Many thanks for your reply!

I anneal after every shot. I f/l resize using a Nitride bushing (.337 at the 'mo as the case neck thickness is .015 to .017)

You are cruel dude!!! (Cannot find smilies)

Many sincere thanks, advice logged in my noggin!
 
I use K&M neck turning equipment and have had great success with it. There was a tutorial video on YouTube of a guy using K&M neck turning stuff that I watched to help me get started. It’s not hard to do once you get the cutter set up. A little trick I do is use RCBS case lube on the pilot and cutter. Keeps things smooth and cooler. Best of luck on your endeavors.
