Re: Nosler Custom Brass ?
Like I said, it's good brass, and six reloads isn't "bad" for many brands of brass when pressures are at a normal max. Not thermonuclear pressures, mind you, just normal industry maximim. Federal's another that tends to be fairly soft, but I've seen (had) 20+ reloadings on cases that were fed lighter loads. Still, it's all relative. I do a lot of Service Rifle competition, mostly with ARs these days, but spent many years with M1s and M1As/M14s. For the Garand-based family of Service Rifles, you get three, count 'em, three (3) firings before you scrap your brass, period. As I said, it's relative.
The Winchester stuff you mentioned (generally) tends to be a bit harder, but again, probably not as uniform, dimensionally. For some this would be an advantage, for others, they'd choose the uniformity over the durability. Ask around here on the boards, and find out what everyone else is using and what sort of brass life they're getting. Nothing's gospel, but you'll probably see some trends that might steer you in the direction of what you want. Hope that helps,
