How far do you turn?

[P1ZombieKiller]

Asking the 30br shooters how far do they turn their brass onto the shoulder?

Not asking other calibers that have the shoulder angle change.

I'd think this would apply to any standard BR case, turn my 7BR brass a smidge more.

Wes, I go in a little further. I just turned a bunch, I will take a picture when I get home tonight.

No need. I noticed this latest lot# seemed to be a little longer than the previous lots.
My cutter indexes off the end of the case neck, so longer neck, less cutting into the shoulder.

And this got me thinking, so I wanted to ask others what they do. I had changed the mandrel to allow a little bit more cutting distance.

This was more of a "wonder what others do" type of thing. Its cold here and I am bored, so the mind is going a little crazy.
Its not often here in Texas that we get iced in.

I normally kiss the shoulders with the cutter when turning my 30BR cases.

Same^^^.....but Wes taught me that when I first started making 30 br brass

Does everyone use a 30° cutter? Someone suggested once to use a 35° cutter to make the transition on the shoulder nicer. Anyone actually doing this?

I have a 30 degree and a 40 degree on my 30 cutters (I run 3 different 30 cal cutters).

The picture above is on my .010" cutter and it is a 30 degree. My .00955" and .0105" cutter have a 40 degree (not by design, just started doing that when I set.those particular cutters up).

It actually does make a smoother transition.

This is why I think turning on an IDOD is better, its indexed off the shoulder. There for no matter lot to lot variations every case turns the same. Imagine if you had some cases with shorter than normal length necks and you rapidly turned on your old school mandrel turner and cut to deep into the shoulder and didn't really think about how much you cut off, Fast forward to a match and boom you blow the neck loose from the shoulder, now you have to deal with a stuck neck in your chamber... don't say it can't happen because I've seen it first hand with a very experienced bench rest shooter. He had a full box of cases that this happened to and pretty much after blowing 4 necks off in one match he packed up and drove 300 miles home. I can turn cases all day several hundred at a time and every single case will have just a touch on the shoulder NO MATTER how short or long the necks are...

Wes, here is a case “blown out”, (not necked up), to make the 6BR Lapua into a 30BR, and the finished neck turned case.

Of course you know I single point them in a lathe.

Size and trim and mandrel before turning if you index off case length or neck.

My 30BR necks are turned a little more into the shoulder. I use a Forster outside neck turner. Works great

I think you’ll see better results if you trim all your cases to the same length before you cut the necks down.

My results are fine. Every single one in the picture is exactly the same. This is where I prefer to turn the necks to on my 30's. Just a good kiss of the shoulder.

Since this batch was a smidgen longer than the last few batches, and I needed to adjust my mandrel, I was just wondering how everyone else was doing theirs.

Here is a close up of my picture above.

Wes, I blend a bit further down the shoulder. Cutter is 35 degrees. -Al
