6x47 lapua neck turn question

[stroked96s10]

This is the first cartridge I've neck turned, 6.5x47, full length to 6x47 and ran through K&M expander. I then turned the walls to .1015" (my chamber is .267). I noticed the neck turning cutter doesn't go all the way down the neck before bottoming out on the stop on arbor. BEFORE doing any work to the brass, as a 6.5x47, Lapua brand cases, they measure 2.840 +/- .0075 tops on a caliper. After the FL, expand, and neck turn I'm at 2.845 to 2.846. I don't see a "standard" case trimmer like I have for my other calibers. What trimmer can I use and can I adjust the arbor so I get all the neck or do I trim cases past trim length of 2.840? Any help is greatly appreciated, thanks.

Read the instructions! You can adjust the K&M to turn as much of the length of the neck as you want. If you don't understand the instructions, call Roger Miller.

I see that, but what about case trimmer? The instructions that came with this stuff is still harder for me to understand because it's literally all brand new info to me. I've never touched these tools but I understand the idea of it all, I'd just rather not waste any cases if I don't have too. Like should I take it all the way down to where shoulder meets neck? I'd assume so...?

You need to go 001-002 above the neck shoulder junction, fire the casings again until shoulder is square then do the final turn making sure you do not cut into the shoulder. You may have to bump shoulder back slightly to chamber loaded round in chamber.Trim brass after 3 firings all the same length .005 under max length. The brass in the picture you posted needs to be turned about 1/6th lower at least.

You are aware that you adjust the length of your cut by setting the depth of the turner mandrel.... And you also know how to adjust the depth of said mandrel..
So your real question is how do you trim all your case necks to a uniform length so as to get a uniform cut into the shoulder.. Simple , you trim them after they have been sized down to 6 mm then expand on k&m mandrel.

So yes you need to trim with a trimmer that bases it's measurements from base to mouth.. and this needs to be done BEFORE you turn them , luckily in your case you haven't gone far enough down the neck with your turning so you are OK at this point to trim to a uniform number 1.839" if you wish and then begin adjusting the length of the cut on a piece of brass till you get the desired cut into the shoulder junction.

Is that not what you're asking? Lol

Essentially with your necks turned as shown you will have a terrible case of doughnuts forming due to the remaining material still left at shoulder junction.

I would highly recommend that you check out this sites technical articles pertaining to neck turning.

good luck

The cutter needs to cut into the shoulder slightly, something like this:

Sounds like I may be getting ahead of myself. I don't have the gun in hand and don't know when I will. Last I heard he was waiting for the action still. I read everyone's replies, as well as spoke in person to another guy who has been helping me learn this stuff. I need more info on the chamber before I continue I think. All I know is it'll be a kreiger barrel that he'll chamber and join up to BAT action. The chamber will be .267. I do NOT know what the trim length should be though. I'll look into getting a lathe trimmer and a 6mm arbor. I'm used to my basic 223, 308 and 300 trimmer I just do with the pilot and cutter. I turned some more of the neck, as far as I felt like it should be and this is where I'm at now. I apologize for my lack of knowledge and I am reading the other threads and articles on the site.

I'd say you're on the rite track now.

Good luck

You need a little more cut into the shoulder. Almost there.

Looks much better. After the first cycle, check to see if you need to touch up or send the reamer down once.

Is he reaming or turning?

If turning, he would have to size brass with a non bushing die so that he can size the entire neck, he then would need to expand the necks again with mandrel that matches the turning tool mandrel, and finally turn again. I would go ahead and do it now and be done with it. Adjust the turner to cut slightly more into the shoulder and you will be fine.

I ran the new 6.5x47 cases through forster FL 6x47 die. Then through the K&M 6mm expander. Then through K&M turner. First pass from .0135 to .0115-.0120, and second pass to .0105. I'll adjust the to turn a little further on the shoulder. Thanks for the advice guys.

Ahh!!! My turned brass is not "Cortina" approved either. Lol.

I have a PMA neck turner with a 35 degree angle on the cutter. Guess I need to go down a little bit more on mine as well. Mine looks similar to the pic above where I did just into the shoulder to remove what hopefully is the potential donut.

If he gets a doughnut, he will need to be ready to ream it. He is turning, but that isn't a guarantee he won't need to touch up after a cycle and also to watch for a doughnut formation and be ready.
