Starline makes the super duty brass for the two kickers
..that being said it's the identical case bit for the 1/16" longer case of the 460..Guys are loading 38000PSI into the smaller Super case with No Problems..
What I am looking for is a hand loader that can load the extra hp into the 45 Super '..If your loading 460 Roland now you know what I mean. The oal is the same on both rounds...I would like this load pushing a 275 or 300 gr cast ...Maybe 100 rounds for starters.....
