Pleasant surprises with my old .270 winnie

[Phil Rizzo]

Is that using 270 win brass or something else?

I have lots and lots of good .270 brass....one of the reasons I stick with it.

280 AI is very impressive for the amount of powder it burns, I can't help but think a .270 with the shoulders blown forward and sharper would be equally efficient.

Sorry, late getting back to you.
Yes, 270 win brass will work.
