I went back to dry tumbling, then quit cleaning all together.When you say you went back to tumbling but no SS pins. Do you mean you just used water, dish soap and some lemon shine for example? Please explain

Dang fine shooting Alex! Do you believe more neck tension is more forgiving as far as annealing vs non annealing?Our match season just began. I just wanted to update the thread. Keeping it simple still works. These targets were shot back to back in the same day in a registered IBS 1k BR match ( 1.6" & 1.5"). 6BRA, 103 vapor trail .008" in the lands, 31.1 of H4895, non annealed brass, .005" neck tension, primers seated by feel with a 21st century seater, FL bushing die, no mandrel, .0035 bump with an ejector, didn't even clean the carbon out of the primer pockets Tune the gun guys, all the anal stuff doesnt mean a thing if you not in tune. Buying the high dollar tools will not help an out of tune rifle!

In theory your correct. In practice I know this brass will continue to shoot well with the same neck bushing for the life of the brass. The life of the brass is actually longer than I typically keep it. I usually make up 100 cases for each new barrel and just retire them once the barrel is shot out, but theres nothing wrong with them. If I was to anneal this brass it would not shoot as well. I dont anneal it because I have tested it enough times to know that. If you find a combo that likes light neck tension, that will be a combo that will respond better to annealing. While annealing does keep the cases consistent it also softens the necks, in many cases that hurts accuracy far worse than a little inconsistency in the neck tension.Qustion regarding neck tension: considering the extensibility of brass to resist deformation when a bullet is seated? Each piece of brass will yield a specific amount of hoop force - grip depending on the amount of interference, along with the condition of the brass.
Hardness - softness of the brass, and surface condition.
How do we keep neck tension consistent, without keeping the properties of our brass consistent? Annealing seems to be the answer.
How far from the lands and what bullet in the 300 prc? Curious because I've found longer jumps like more neck tension but it's a small sample compared to your experience and maybe it had something more to do with my tuningI dont know about that. Some combos just respond well to higher neck tension. It shows up more at long range. I could not tune the vertical out of my 300 PRC at 1k until I increased the nt to .005" it shot well at 600 though. My 338s have all like very light nt. You just have to shoot the groups with different bushings to know.
The only neck tension theories that count, are the ones field-proven down range.In theory your correct.
I have been shooting 1k for a long time. There are so many rabbit holes you can go down. My opinion is that 99% of your rifles accuracy is the tune. Sorting and measuring help but not until your at a certain level. Glenn Kulzer shot 8 new records in 2021, no other feat has come close in 1000y shooting
Thanks for the info.I dont know about that. Some combos just respond well to higher neck tension. It shows up more at long range.
