Lessos learned loading my first 308x45 cartridges
Lessons learned loading my first 308x45 rounds...
(1) After the necks are inside reamed, set up the shortened Lee Collet Neck Sizer according to standard "Touch shell holder plus one more turn." If you don't do this, the necks will not hold the bullets, contrary to my previous thoughts, it is not necessary to use a Factory Crimp die after bullet seating for a bolt gun, but maybe necessary for a semi-auto.
(2) If you take a close look at the cases in the tray, there is one in the middle that has powder grains on the upper part of the neck. They are sticking there due to left-over oil from neck reaming.
****Warning: If you don't clean them off and seat a bullet, like me, you will get a bulged neck that will not chamber. I had to disassemble the round, run it thru the FL sizer and neck sizer and reload it.****
(3) I seat the Hornady SSTs to the cannelure. This gave an overall cartridge length of 2.4900". Nominal design allows for 2.555" maximum cartridge length, but some super BC designs will probably be able to be loaded longer.
A habit I formed a while back is that I make a dummy round for every bullet I buy and put it in the box of bullets. Sort of a reference round.
Range Thursday or Friday.
