Neck turning question

[IHFarmer07]

I was changing the cutter in my K and M neck turner to the angle of my brass to better cut to the angle of my 6.5prc.....30* chambering.....33* cutter and while doing so, I needed to reset my cutter depth and these are part of the pieces of brass I was setting it up with.

Curious if you guys would load and shoot these? I might have taken a .001 or .002 too far....not really sure but on one I can catch my finger nail all the way around and the other two part of the way around will catch my nail and the other part don’t , which I believe is better but still a lil deep, I think....let me know if you would trash them






And what my end goal was/is or what it should’ve been, I think anyway, let me know your thoughts.

Thanks
Eric

If you’re only referring to a couple pieces of brass I would scrap them. The whole point is consistency. Why run several pieces of brass that have less neck tension than the rest.

It doesn’t look like you would hurt anything with that extra .001 removed from the neck/shoulder area. However, I would load them to use as sighters and scrap the brass after 1 firing. I would mark the case with a sharpie somewhere so I would not forget.

as stated earlier, consistency is key. What material is now in the shoulder will eventually be in the neck as the brass grows. If you thin the shoulder on some pieces and not all of them then you may eventually find that those pieces become problematic because they have less material in the neck. Not worth saving the $3 worth of brass if you ask me.

All the brass has been already neck turned, this is going on the 4th firing of this neck turned brass, but not all were cut that far on to the shoulder, just 3-4 pieces.
The reason for cutting up a little more on the shoulder was for donuts. At almost 1100yrds it was showing up on the target that I had issues with the donuts.....I thought I’d see what would happen if I didn’t inside neck ream....that process sucks btw, and the groups sucked. It turned a little under a half moa gun into a 1moa gun at a 1083yrds. Never knew how to properly neck turn so experimentation took me to this, and a guy on YouTube from the UK has a great video on this, but the k and m turners come standard with a, I think 50* or 55* cutter and you can F some stuff up on the brass.....I found out the hard way, so note to myself......get the proper degree cutter to the brass shoulder degree!
Thanks for commenting though, should’ve been a little more descriptive on the matter/process/what’s been done, but it would’ve been as long as this lol.

Ok, I see what @hafejd30 was saying......thanks for lol “spelling it out” a little more for me to fully understand, been a long day today.
