I use RCBS dies, and they should be around $30 for the set.

I've been loading 130gr Nosler BTs for my 270WSM, but will be loading some 140gr BTs and some AccuBonds up as well. I'm using IMR 4350, pushed to max load, WLRM primers, Winchester Brass.

I noticed that the seating depth is very finicky on the short mags and the super short mags when I started load development, took me a lil while to find the "sweet spot".
