I bought some WSF for some non bunny fart 45acp and 40s&w loads. Waiting for a lee shellplate for my hand primer in 40s&w so I've only loaded it in 45 so far. Meters nice,burns clean and I like how it recoils compared to most factory ammo. Shot some last night and flash was minimal. Between WST & WSF i'm pretty well covered for what I load. Both work well in my Uniflow also. I did already break a pin in my RCBS 40/10mm die. I really like the Lee dies decapping pin set up.
