Used in 50 CVA Mountain Rifle, 1-66" over 90gr FFg and Wonder wad. Would hold 3" at a hundred off a bench. Would put lube on in 'coats'. Used TC bore butter, let it nearly dry then coat again. Did this two or three times. Older and drier they got the less messy they were to carry and still shot great. Might mix BB with a little beeswax to go faster and stick better. Just kept a few in the possibles in an open sandwich bag.
