For your COAL are you measuring from the tip to base or ogive to base? Tip to base COAL can vary a lot more.Was watching a long range only video where he was setting up his dies and was caming over both the seating die and the sizing die. I have never done this before. What are others doing? I am trying to find a way to get my reloads more consistent. I typically have very little variations then randomly I will have a COAL that is outside the norm but my process feels the same so I am unsure what is causing it. THinking if I use the caming method that may take this away. Thoughts?
It really works with the collet dies.......time it takes to get the next case ready (5-10 seconds) is perfect.I’ll have to try @ButterBean ’s technique of holding the brass there for 10 seconds to prevent less spring back. Hadn’t heard that before but makes sense.
This.I never have the seater die touching the shell holder on conventional die sets. As mentioned above, the crimp feature will touch the case mouth doing so.
Just bought one in 243 Win to play with. Loaded 10 rounds using Lee instructions for a RCBS press that cams over.Lee Collet (neck) die
Youtubers kill me when they size a case or expand a case neck in there videos. You would think they were running a marathon. Always seat a bullet slowly, and expanding/Collecting case necks should be done slowly and held for 4 to 10 seconds depending on the brass. Consistent annealing after every firing is a must. Think of it as relaxing your brass. I don't need any uptight brass hanging out in my reloading room. If I want that, I'll invite the wife in.

That's why I cam over, It takes all the work out of it and it makes it consistentJust bought one in 243 Win to play with. Loaded 10 rounds using Lee instructions for a RCBS press that cams over.
Placed 28 pounds of weight on the lever to size, because Lee FAQ said 25 lbs minimum would put 600 lbs on the ram. Neck tension not good. Measured mandrel at .240"
Takes a lot more force/effort then my bushing die.
If I feel like "working out" I will get out the Lee Collet Neck Sizing Die.
I don't set mine up according to lee's instructions, I use the J. Valentine method that comes up in most searches on lee collet neck die adjustment from Benchrest Central. Less collet lines in the neck and less pressure to size, find it and read it, this guy put some time into figuring it out. Its a case of lee making a very accurate and concentric neck sizer, but not explaining how to adjust it properly at all. I was ready to give up on the first one I bought till I stumbled into the different adjustment method, now I have a collet neck die for every cartridge I load for. Too much pressure and you will remove the alum. cap without screwing it off as mentioned in other posts. If you can't find it PM me and I'll send it to yaJust bought one in 243 Win to play with.
