For cold weather, I use mink oil from Track, or neetsfoot oil. They both allow multiple shots - up to at least 20 without wiping with heavy loads, and using normal target loads under 100gr., unlimited shooting - especially in the .32 and .40. I found them to load no differently than windshielf washer fluid and soap, ie: easy, all day using mink or neetsfoot oil on a trail walk - up to 60 or 80 shots.
One of the cast bullet shooters over on another forum, who is a noted cast bullet accuracy shooter, picked up a TC Renegade in .54. He reported it shot fairly well at 25 yards, but lost that accuracy in 15 rounds shooting bore butter as a patch lube.
He scoped the bore and found a buildup of something greasy in the corners of the groove and land, which required his normal nitro solvents to disolve. Accuracy returned - to fail again in accuracy in another 15 shots. He was wondering if everyone had this problem. We got him changed over to a better lube, recrowned and thicker patches, now he's happy- a new BP shooter who doesn't have to wipe while shooting- all day and whose accuracy remains good, all day.
