They were originally based off the 50 Beowulf round but they necked it down because there were more offerings in the .458 bullet lineup!

Southern Ballistic Research SBR is now using Shooters World SBR SOCOM Smokeless Powder.

QuoteSBR-SOCOM is a canister form of Explosia bulk propellant D063-01. There is no Lovex canister equivalent to this propellant.

This is LOVEX D063-01
