Was loading up some .243 cases tonight (only had to do powder and projectile) and found that once the proj. was seated I could easily twist it around and pull it out. My BIL ran all the cases through a Lee Collet die.
Figuring he didn't the die up properly I re-ran the cases through (after I adjusted it as per the instructions) and I could still twist the proj. out. Stripped the die down and measured the mandrel. It came out as .240. This is the same as the projectiles I am using (Highland) so I figure the necks need to be a bit tighter to hold the proj. properly. The inside case mouths measure .240
I lubed all the cases up and ran then through the FL die and measured the inside of the case mouth. Came out at .235-.237. Seems that they are going to seat the proj. OK now.
Does anyone know if the mandel in a .243 Collet die should be .240? I am thinking it should be less.
The cases are a mixture of Winchester and NNY (Marketed as Highland in Australia). The NNY cases look like they are annealed.
I'm off to tear down the Collet Die and to make sure it is clean. I have a set of Collet Dies for .223, .270 and .303 and haven't seen this problem before.
Any help/suggestions would be appreciated.
Thanks
