    I did a quick search and didn't see what I was lookin for. I have a surplus of 270 win brass that was given to me and I'm wondering how difficult it would be to form it to 280. I've been reloading a couple years but I haven't formed brass yet and I want it to be easy but more importantly done right. It will only be used for hunting so what would I be looking at?

    yes you can do it, but it won't be easy. Two ways to play here. You will have to move the shoulder as the headspace on the 280 is a LOT longer that the 270
    1.---You have to neck the brass up to 30 caliber, then down to 28 caliber to create a secondary shoulder to headspace on. trim to length and square after necking to 280... fireform with mild load
    2.--- neck to 28 cal in a 280 die , trim for length and to square, and seat your bullets long enough to make hard contact with the rifling and blow out the shoulder using a mild load (start charge).

    I'd actually do both if you have the ability but either way on it's own will net you usable brass

    With the standard calibers it's really better to find someone to trade brass with than to mess around with forming brass. That said, if you've got the time and are careful, it can work well.

    Yeah that's exactly what I didn't want to mess with. I'll just sell the270
    Brass and buy the 280 stuff. I appreciate the insight
