First time neck turning 6ppc

[long40shot]

Hello all. Well, this morning I neck turned some 6ppc for the first time ever. It seems to have went well. I used a PMA tool. Let me know what i did wrong.

Nothing, if you are happy we are happy. Twist them in a scotchbrite and it will all blend.

I use the same tool. A little 000 steel wool or scotchbright will even out the shoulder lip. If you back off just a little when you feel it hit the shoulder, the step will be softer unless you are taking a lot off the brass, then it's hard to not get a step that big. It's no big deal though, looks good.

Guessing you used a 40 or 50 degree cutter? What thickness did you turn them to? Looks good to me but I’m trying to learn myself.

I would personally not turn into the shoulder that much, but i think they will be fine the way they are. Won't hurt a thing.

 

[Steve Donlon]

I did these yesterday, 6.5 Creedmoor. The PMA tool is made to cut into the shoulder, so after the first firing, the edge on the shoulder will be gone. I've never had a problem with cutting into the shoulder.

I normally turn into the shoulder little less than half that much but as mentioned it will probably be just fine.

Years ago I was told that turning down onto the shoulder slightly will reduce the odds of getting a donut.
Seemed to work out but, as mentioned above, I didn't go down that far on the shoulder.
May I ask what your target thickness was for the neck? Turning for a .262 neck?

You should barley touch the shoulder. Cutting into the shoulder reduces the thickness by a couple thou. I would remove donuts with in inside reamer. I don't worry about donuts since I shoot 58-65 gr bullets in my 6BR and 6BRX. The bullets are seated about half way down the neck.

Looks good. Keep up the good work. Always make sure you have enough clearance with a bullet on the case and measure again (AKA a dummy round). If it's a tight neck.

Looks pretty good to me.

After I do my initial cut, I go over it again for what I call the " fuzz cut ". It cleans up those little lines left behind from the tool pressure spring back. Bring the tool back out slowly. Then a little steel wool, on the case mouth as well while it is still turning in the Benchrite Case Lathe. I like seeing the tool work, that's why I use mostly PMA and not the Pumpkin anymore.....I AM a little OCD...LOL...I actually like neck turning.

Recently turned for a .262 neck and went to .0085 x 2 + .243 = .260 loaded neck diameter.

Always check the bullets actual diameter (pressure ring) . Most bullets are not 243 or 308. I've seen 6mm bullets measure 2428 to 2443 on different brands/ lots of bullets. Best to check with a loaded dummy round as mentioned earlier. Looks pretty good to me maybe just a bit further then I usually turn into should but it will be fine.

If necks stay on the case body after a few firing, you did good.

This^^^^^

Also, what the reamer cuts may be different than what the print says.

When you have a nice sine wave on your neck after a couple firings, you have arrived.

And the chamfer looks aggressive. The case mouth looks knife-edged.

My rifle is a older shilen barreled .262 neck. I have no print, shilen can't even find it in their records. I was going for a .260 loaded neck, but ended up at .259. I didn't think it cut that deep into the shoulder when I was doing it, but maybe I screwed up. Yeah, the chamfer on that one is a little much, oh well. I trimmed them to 1.490, it's alpha brass btw.
