Thicker necks are the culprit here yes, I'm convinced now. Different manufactures vary in neck thickness.
Makes sense... I'm convinced. Kinda like FL sizing too much and the case has to be trimmed. The brass has to go somewhere, ya learn something every day !
I don't bother calling Lee anymore, everytime I get some guy that argues anything you say, one time he told me the bullet should seat to the exact same oal everytime with no adjustment, I said what if one neck is more work hardened, what if one is thicker brass, well he then backed off his claim, I really wonder if these guys know much about reloading.
Yeah and his name was John, right ? I made an oversized mandrel for my collet die but it doesn't work, he tried to tell me about my bore being oversized, I hung up on him. .
For years it was the same gal and one guy who handled phone calls.I didn't think I needed the mic but after I got one with it I converted my other ones, just makes it much easier.Yeah and his name was John, right ?
I learned to compare OAL of bullets, that helped some for COAL. I'd like to get the add on mic for my Redding seaters.
The 6.5 was small primer and the hole was smaller than 223 hole, I think it was just particular to that Lapua brass, have no idea why they made it so small, I returned it and got large primer brass.
Ha, I like annealing
Problem with full length die with expanders is expander knocking neck out of whack, just a little uneven pressure on base by shell holder will knock it out as it's pulling out of die not to mention really working the neck, how good is that for neck tension. Friends don't let friends use FL die with expander, lol.
If you notice the new lee collet dies have a step in the mandrel around 1/3 of the way up, the old ones did not and would kinda pop as case came out of die, this was because they were a tiny bit thicker at the end, you could actually feel a little more pressure just as mandrel came out, I didn't like this cause it was sizing where it wasn't meant to size. I took the mandrel out and lightly tapered it at the end by chucking in drill and 1200 sandpaper, eliminated the pop and reduced my runout. I called Lee about it and he told me the pop was from the case going from the mandrel to nothing, I said why do I feel more pressure on handle as it's coming out at end of mandrel, he said cause press has less strength on the upstroke which may be true but all of a sudden as neck came through end? Anyways now they step the mandrel so obviously there was a reason for it, the end with the decapping pin was slightly thicker just before it went down to the pin and it shouldn't be. So I don't call Lee anymore.
what's the upstroke have to do with feeling pressure coming out ? of the "down stroke" ??less strength on the upstroke???
the shell holder dimensions are loose to allow the case to float. The expander/decapper in the die is suppose to float but not enough in my opinion. Forster has a rubber washer between thier bushing and lock nut to allow floating, and the elevated expander. It really doesn't do good job. I went to 21st/sinclair expanders, then to body/collet neck die.
That one had me scratching my head as well.
