And I appreciate that we all may have different opinions and that's healthy.J.D. said:IMHO, based on my experience and research, a good oil, or very light grease are much better preservatives for modern ML barrels.
For the record, I clean my steel bores so squeaky clean with dishwashing detergent after every use that the bores are bare raw metal and if I don't dry them immediately they flash rust.
Point being there is no buildup, no seasoning allowed in my rifles. However, I do use Natural Lube 1000 as my bore & patch lube...plastered right back in the bore in large amounts smeared onto lubing patches...only lube I've used for 17 years in several rifles, never lost a barrel yet.
IMHO the problem that some claim to have with bore butter is a user problem, not a lube problem...people either don't get a bore 100% clean and 100% dry before they apply bore butter over the top of what they've left behind...and/or...they don't apply enough of it.
