Interesting range results. I took the rifle out cold and fired ten shots with the Permatex/Ivory lube out of the barrel that had last been fired with a long string of paper-patched boolits lubed with JPW. No cleaning beforehand, and the leading edge of the rifling still had the faintest hint of lead in the very bottom corners from some soft hunting loads I'd shot before the last string of PP. Three into an 1-1/4" triangle, then it settled down into a half-inch group, this is at 50 yards. The rifling was clean as a whistle, no lead traces, and an oily film was evident in the bore with a slight lube star.
So I let it cool for about 20 minutes and fired five of my "standard" load, exact same as the first group, but with Summertime Felix lube. Four went into 1/4" which is fairly typical except for one flyer because of the jerk behind the trigger and a creaky bag/stock interface.
The strange thing is the muzzle end was bone dry and streaked with light leading in the grooves, not a problem I usually have with this load and lube. I think the Felix lube didn't like the other stuff, or there was some leading from the first string somewhere that worked its way down to the muzzle.
I'm going to try more of the synth. grease/Ivory stuff later, with a clean barrel and shoot a lot more of them, also at longer ranges.
Another observation was that the synth. grease/Ivory group was a full inch lower at 50 than the FWFL group, which is very consistenly dead-on at that range. Looks like I need to chronograph the next batch, too.
