Re: Help me figure out what Im overlooking

Ok, so I think I have it sorted out. I took the die apart and it was pretty dirty. Sprayed the die with some carburetor cleaner and put things back together and the readings tightened up considerably.

Thanks for all of the good ideas. There were a few suggestions that people made that I would have never thought of for sure. Thanks again guys.

Re: Help me figure out what Im overlooking

I have had this happen after the brass has been shot 3 or 4 times. Especially if I am loading brass that has mixed shot counts. For example some have two shots and some have 4. Seems the necks are worked harder on the ones with more shots and it takes a little more pressure from the seating die to get to the right seating depth.

Annealing the brass has helped before.

Well, they are mixed. Some once fired. Some several firings. There was a difference that I noticed in the amount of seating force needed.
I can't wrap my head around why that would make a difference though.
If I'm using a press, the die doesn't change, why would that make a difference in length?
I can understand why it would make a difference in neck tension.

It would depend on the press you have and how much use it's seen, say it's a good press but generations and 10's of thousands of rounds old it could have wear in some areas, or if it's weaker press type (C frame, cast aluminum) those can flex also. But Presses like Lee's classic cast, RCBS Rockchucker, ect are built very solid I can't see them flexing under normal use in good condition.

If there's more force needed to seat some bullets, and other go easier... and you said the cases were fired different numbers of times... it's time to anneal the cases with the larger number of firings. Some of the brass is more work hardened than other pieces, and that's the reason for the variation in seating depth resistance. And likely the reason for your varied OAL numbers, as cases may not be springing back to the same shoulder position when they come out of the sizing die.

Anneal all of the cases... then you should find that the bullets seat with the same pressure on the handle...

Thanks Dan.
I have never annealed before, but I have been c
