I use GM210M in my 270 and FED 215's in my 7mm Mag...I don't currently reload for my .45 so no help...
As SKB noted, I was in a Bass Pro Shop today and a Cabelas Saturday...I bought the last 2 bags of 308 brass and the last 2 bags of 270 WSM...there was probably a dozen other bags of rifle brass at either store and they were 222 Rem...204 Rugar...45-70...and a bag of 338 WBY...there was no primers at either store and maybe 30 pounds total of powder...not a single .22LR or .223 round in Bass Pro...not 1!
