RCBS 300 Whisper dies purchased from JD Jones/ SSK Industries. These are Series H dies, # 55010, made before the advent of the 300 AAC Blackout. The 300 Whisper was originally formed from the 221 Fireball case, so the unmarked die is am intermediate neck die expander that expands from .22 to 7mm, then size with the FL sizer to expand to .30 cal. SSK Industries no longer has the RCBS dies made for him as he switched to Hornady Dies and components a while back.
The dies are in very good condition. I have used these dies to produce ammo for my original T/C Encore in 300 Whisper, and my 300/221 wildcat, and my Daniel Defense 300 AAC Blackout SBR, before I purchased Redding dies in 300 BLK.
