I used those too, until I set something sharp on it when it was thawed out. I needed something a little more cut proof.
Acceptable neck turning variation

I just wrap it in a thin rag. That protects it and also keeps things dry. Even a paper towel. I guess it could still get cut but a lot less likely.

i wasn't smart enough to think of that.

I think brass prep methods can change the affect of neck thickness variation. If you size with a FL or bushing die the variance will change neck tension. If you follow up with a mandrel after necking down it will reduce the neck tension variation. 0.0003 is very minor in my view - less than 3% for most brass.
Corrected decimal point.

I wonder by what percentage jamming the bullet negates neck tension variation too. Most SR BR shooters are jamming by some amount.
I'll just say that I've gone to mostly no turn neck chambers, even in my BR rigs. Reason...it's easier and I simply can't see reasonable neck thickness variation on the target. And yes, I think that's why we are seeing more no turn chambers in BR now. Not a thing wrong with neck turning if done properly. If you THINK it helps, then it really does help. At some point, clearance is just clearance and any small tension variation is what we split that hair over, for the most part. And like I said...I wonder how much that too matters with some amount of jam that makes sure the bullet doesn't move before the neck opens up when fired.
As usual, if ya can't shoot the difference...is there a difference at all, or not? Internet is awesome but testing is how we KNOW stuff. But sometimes ya have to go into testing with zero preconceived notions. That can be where the internet is a detriment to learning from actual testing. If the whole internet says ya gotta turn necks, you'll likely go into testing it with the assumption that it's best. I don't do that...or at least, I try not to, to the best of my ability. Rather, I often go into it trying to disprove things equally to trying to prove them to be true. Either way, I just try to be as neutral as I can.
There's more good info on here than bad, by far. But test things with an open mind to finding that the internet gospel is often as much gossip as it is gospel.
you don't jam bullets in a hunting rifle, you just dont.
Many make cases from a parent cartridge, by time you get it all sized and necked down the necks are just to thick plus you need to cut them down if you have a tight chamber to start with. If it's a factory rifle, then leave neck alone but if its a wildcat build or what have you, need to turn necks. It also doesn't hurt to just clean them up a little so more uniform so when bullet is fired it goes into throat same each time. Out of round neck will throw flyers.

Well, you can. There's a reasonably wide area between touch and sticking a bullet. I do it on most of mine but I'll admit that my reply was not about hunting rifles too. Yet another reason to work from "jam" and then backward from that point. You can start at the point where a bullet sticks and work backward from there. I say that mostly because most of my best loads over the years have been between .010 in and .010 out of the lands. Really, pretty much all of them have fallen within that range. Jam doesn't necessarily mean ya dump powder if you try to eject a loaded round...by a long way actually.
Hunting loads I seat .030 from lands. no matter what I reload for.
Also take into consideration case that have alot of brass flow like a 22-250. after reloading it over 5 times the necks will get thicker on you, all the brass does not just flow to end of a case. Take a bullet where base of it sits past the neck and shoulder junction, you will get a buildup of extra brass there, it's called a donut.
Give those creeds another year and you be hearing same thing about them along with carbon buildup. Its a given.

Then its not jammed! its .010 off of the lands.

I am one that's been around for a while and I can agree to a pont...but no, in no world does jam equate to jump. It used to be that what people called "jam" was the bullet seated at the point where the given neck tension would not allow it to be further "jammed." I now refer to that as "full jam"..fwiw. Facts haven't changed but internet terminology has. Nowadays, the majority of people seem fixated on finding a very precise "touch point." By that definition, anything forward of touch, is jam. But ya can't have touch and jump at the same time, by any method that I'm aware of..and it just wouldn't and doesn't make any sense to say otherwise. If it's touching, it's touching. If it's longer than that, it's jammed by that amout and if it ain't touching, it's jumping.
By most anyone's definition, this is pretty understandable.
yep and in a hunting rifle you don't even want it touching. or kissing rifling. another thing ammo in an ammo box does funny things when it's in back seat or wherever. its called vibration. Vibration makes Nuts/ bolts come loose it will also cause a bullet to settle into a case deeper or out farther depending how you put ammo in ammo box.
You should stop now. Myself and others on this site are national champion shooters and world record holders who carry ammo to the match. We're happy to help but not so happy to be told what vibration is. I do hope ya hang around though.
I assume you mean both mine and yours. Good luck to you sir...or ma'am. I'm honestly not sure. But I've been kind and considerate. And yes, on the subjects we have conversed, my mind is set. Please bring up something that makes me consider and appreciate your thoughts more vs telling me what I don't know.
You were a hell of a lot more patient than I would have been. Good on you.

Now he's pm'ing me stuff to tell me how he's not new to this. I truly have been nice and tried to be helpful with this guy. I'll stop at that for now but just read his posts to date. I do hope he'll stick around but have tried to politely make it clear that his approach to date might not serve him well. He just brought up the late Stan Ware. I'll stop there.
