I have had this idea in my head for awhile now but just haven’t followed through with it, After shooting Harleysboss’s .45 Cal Grease Groove bullet, it got me to thinking i need to make it happen! It’s The Lee S&W 500 bullet as a GG in my .50 Cals, Harleysboss’s new .45 Cal GG and the Lee S&W 500 are very similar in design, with inset grooves instead of exterior bands. I am gonna try these Lee S&W 500 bullets as a Grease Groove in my Stainless .50 Cal Green Mountain LRH 1:28 Twist. I took the Lee C501-440-RF Mold up to a Machinist friend of mine and had him Bore the Gas check Shank out. It turned out really good :yeah: I poured up some to test, they measured .502-.503 with my 40:1 Alloy, and weighed in at 460-461 Grains. I Pan lubed and ran them through my .501.5-502 Sizer, I loaded my rifle to check fit? AWESOME :yeah: They start good and snug, and stay that way all the way to the powder, I couldn’t ask for a better fit! These will definitely stay put on the powder. Hopefully get a chance to try these tomorrow.
Just need to cut them out in the morning and go :yeah:
