Bear Grease VS spit for lube:
This testing was done in the late 1970's - Bill Large .58 barrel. The testing was for velocity comparison and velocity spread, shot to shot. Test was 10 shots, per load. No wiping at any time.
95gr. 2F GOEX, .575" 285gr. ball .022" denim patch
spit 1,424fps 48fps spread B.Grease no vel. noted 97fps spread
140gr. 2F GOEX same ball and patch
spit 1,683fps 10fps spread B.Grease 1,736fps 69fps spread - this load, with both lubes was my "Accuracy" load, however spit shot into just over 1" at 100 yards, B.Grease shot 2".
This was repeatable.
