Hi guys
New to the swaging, so a lot of doubts.
I received a 224 swaging dies from Blackmon , and I am using the J4 jackets.
My problem is that a feel different resistence in the core seating operation. I have the cores with very uniform weight, so I believe that this isnt the problem. Its necessary to separate the jackets by weight to avoid the problem? The difference in the ogive length is 0.010" from some bullets. Anyway, with a custon 223 rifle, I got very small 5 shots groups, in the .25" to .50" range.
But this variation bothers me.
Any thoughts?
Sorry for the bad english...
