Hey GreyHawk.. not to get into you and your friends " business " I was loading a few 40/60's ( 1hr. ago )sooooo ..I cut down 45/70's measured rim thickness and weighted w/ no primers on digital scales .
Starline................... .062 thick.........179.+
R-P............................065 ...............172.+
Jamison .................... .055 .............189++ ( this brass is head stamped 40/60 )
WW ...................... .065 ............. 167 +
Now my chaparral is a garbage desposal it will smoothly load all of the above but The Jamison leaves to much head space for " MY rifle " so the search for what is best suited for each fire arm is part of the"RIDE" and you know Momma said" never argue with someone...when you know your right" ( ha-ha-ha-ha ).
I really enjoy realoading and I know I'v got a lot to learn ,, this place has been a great place to visit w/ folks who enjoy reloading also.
