So I'm kind of new to reloading and everything says 13 grains and a 40 grain bullet. 13 grains fills the case right to the rim, the manual says compressed load but is it normal for the case to be that full?
OK, here's how I do it w/13.2 gr in either W or R brass.
1) I dump from my Redding BR powder measure into a Saturn funnel held on top of an empty case.
2) I tap the funnel w/my index finger til the powder is below the case mouth
3) I remove the funnel and put my index finger over the case mouth and tap it ten times on the Bonanze CoAx press and then seat a bullet
The tapping settles it almost to the base of the neck and when I come back from Montana w/1,700 empty brass I can load them back up in a week of evenings.
The process takes less time and is less complicated than reading about it.
W/fired brass sized w/Lee Collet Die it is even lower in the case.
I am getting 3,245 across our Oehler w/H 40 Vmax out of a 527 American w/sub half inch accuracy. You wont get that accuracy w/out getting a modified magazine from Calhoon and seating the bullets out or using his SS adapter. At least w/mine and four I have worked with others on - this was the case. But w/factory length magazine it was good for ~ 3/4 inch.
