Hi all

Someone who was at the range at the table beside me was shooting 30-06 new cartridges, he was about to put the brass into the brass bucket when I asked to have them instead, he gave them to me.

Was going to full resize them for my rifle, but I decided to test cycle them in my rifle first, and they cycle really easily in my rifle.

Would be OK if I just neck resize them instead?

Regards
 
You have asked a question with a 50:50 chance of bing correct. But since you actually tried the cases in your rifle, you have a 100% chance of being correct. Enjoy. Your headspace and outside case diameter dimensions are smaller than the other persons rifle. No way of knowing first, but it may have been the other way around. Testing or measuring is the only way to know for sure. You tested, good for you.

Thank you
 
If they chamber easily, there is no issue at all. Obviously your rifle has a chamber as large, or larger than the rifle that the cases were fired in, that often isn't the situation.
 
Quick question I get that the case fits your chamber, what is the benefit of only necksizing over full length sizing?
Thanks!
 
Less sizing will leed to longer case life? Because you are reforming the entire case each time? So do you use a short base die for just neck sizing?
I reload for a couple of my rifles. Not alot. I know my basics . Any info you guys wanna impart on me here is much appreciated!

Not overworking the brass. Setting up a full length die properly does stop some excessive working of the brass. Expensive brass can get a longer life by annealling. I will pay a guy to do mine because at $2+/case, 30 cents to anneal and reset the workability is a good deal. Also, neck sizing and collet neck sizing are not the same either. I prefer collet neck sizing so the expander ball can’t stretch the brass on the way out. The more I have to trim the length, the more of that “excess” brass is being stretched from the bottom of the case. Case head separation eventually results. Not shooting excess pressure loads for greater velocity helps a lot too.
 
It won’t change nothing in 30-06. Neck split or the case head goes toward head separation, primer pocket get loose in 6-8 firing of full power load. Before some jump and say they get more..brand and rifle, proper full lenght sizing ( bump- headspace) are factors.
If you want to extend your brass life, annealing will do more for you than neck sizing.

Full length sizing the proper way, will not shorten case life. Anyway, you will have to full size it, neck sizing only will get you only so far, before case come hard to chamber. Neck sizing was a benchrest technique for custom gun- barrel that have long been abandoned for full lenght sizing.
 
Might be good to know how much the case will stretch.

Measure a case fired in your rifle (base to datum line on the shoulder) . Now measure the case you picked up at the range, same way.

Note the difference, if say it is 0.005" in the difference then the case will stretch 0.005" upon initial firing.

A slight difference isn't much of an issue as long as you size die is set up properly.

If the difference is a lot , then a false shoulder will extend the life of the brass on the initial firing.
 
You are stuck in your belief, but it change nothing to case life. I shoot competitive benchrest, and I can tell you that best accuracy come from full lenght sizing, bump on my gun .0015, not from neck sizing only. The most accurate cartridge of them all, the 6PPC, shoot at it’s best with .002 of bump….

That you load one round at a time or magazine feed change nothing to case life either. No matter what, since that brass was fired in another gun, it will fire form to your chamber and stretch. No two chamber are the same.

Zero reason to neck size only. It’s a holdover from a bygone era where people thought it was more accurate. It isn’t.

Basically, the less you work your brass, the longer it will last. You can buy neck sizing dies, or FL dies (full length). You can also back off your FL dies until they just resize the neck. This will touch the body somewhat, but less than full length sizing. Eventually, after a few reloads, the brass will get tight in the chamber, and at that point you full length size it, and then start the cycle again. As well, some people report increased accuracy with neck sizing only. Though I have read articles refuting this. Try it both ways, and see what works best for you would be my advice. - dan

Your and my needs are different. I just shot a 5 rnd group at 400 that was just over 1/2MOA. Did almost as well the next day shooting off a bag on top of a tripod while standing. That is neck sized brass. Good enough for my needs. Chasing anything better would entail a high level of cost with no payoff for me.
