I agree with William, LB and the other testers out there. Testing is fun, rewarding some times and frustrating at others. Getting down to the crunch here now with the commitment to go to the hunting camp as camp-sitter have arrived. We leave on Monday for 10 days. That gives one day to pack all my junk, and 2 days, today and Saturday to play. Looks like a nice day today, so perhaps today is a 'range day'.
For target shooting I've pretty much fallen back on the spit for lube, but depending on the load (or gun) being used, LHV will get used as well.
As to Murphy's leaving crub in the grooves, it must be getting burn by blowby to do that. That means to me the patch isn't heavy enough. Taylor and I have used the Moose Snot (murphy's/beeswax/castor) recipie in 4 different guns now, with NO residual fouling. I just didn't like it as well as spit or LHV. I still have a quantity stored for further testing or perhaps hunting. I think the $#@* in the bottom of the grooves that harry experienced might have been burnt castor oil- it leaves a heavy brown residue, gummy at worst, in the heads and on the mufflers of our model airplane engines. Again. we didn't experience any residual fouling when using this substance in our rifles.
Nice day - think I'll head for the range.
