Here ya' go ... some empirical evidence!
12-degrees in Vermont, at a primitive MZL snowshoe biathlon many year ago ... whilst serving as a safety officer for 2-hours at the final station, I observed 8 broken ramrods, 1 using spit patched loads and the other 7 using Bore ‘ramrod breakin’ Butter. I had a metal-lined ramrod with me, due to the temps, that would fit any 45-cal or larger caliber. I let more than a few use it, along with Track’s mink oil and they all salvaged their scores at that station. Me thinks we made a few converts to TOW mink oil that day!
But in addition, it really is a superior patch lube for hunting! It does not contaminate the powdah nor dry out, for reasonable storage conditions or time. One guy,
who's actually out in the PA woods for their flintlock season as I write this, will leave his longrifle loaded if he doesn't take a deer. He'll bring that same rifle (stored in a cool place) up the VT biathlon of mid-February, then primes and takes a shot at the practice gongs.
He hits the gong EVERY year ... as he hasn't taken a deer in a while, LOL!
