California's Central Coast Amid The Insanity
I'd like to thank Brad and Pistolero for unknowingly helping me dial in my .45 ACP Randall.
I was having an intermittent feeding problem, with Lyman's 452460 semi-wadcutter, that was defying my attempts to remedy. Seating depth variations were tried, and while some improvement was realized, feeding was not 100% reliable. Replacing the magazines' springs with Wolff extra power springs, again, made some improvement, but the occasional problem would still occur. Replacing followers didn't help at all. Brad, in a rather long thread at the other place, extolled the virtues of Check-Mate's hybrid feed lip design magazines. I bought three. They feed perfectly every time.
Of the three original Randall magazines, two have the GI design lips and the other has the full-wadcutter lips. Weird. They continue to give the occasional feeding hiccup, but Pistolero's thread about a tighter taper crimp has been an educational read. My latest reloads are crimped to .468", down from .470", using a Hornady New Dimension taper crimp die. They will see action at the next opportunity.
By the way, Bill, the interior of the Hornady die looks identical to a '73 dated RCBS taper crimp die, which is dedicated for use with Lyman's 452374. It'll have to be turned down a wee bit too.
Thank you, gentlemen!
