300 whisper/300 aac blackout
I have the Lee 300 aac blackout dies and a couple of M&P 15 300whisper chambered rifles.
I've read all about both ammos, and how you can cut down 223 brass to make 300 aac blackout brass. Also read the the whisper was originally based on the 221, or there abouts.
My question is, how will the Lee dies work on the Hornady brass from the 300 whisper ammo? I bought 400 roundes of this stuff, half in the 208 amx and half in the 110 vmax. I'd previously purchased some 208 amax bullets for use as reloads.
Haven't done any reloading for this yet, not acquired much brass and haven't really shot them much to date. But I'm gearing up to scope one of them and start seeing what they'll do.
