I would respectfully suggest you get a copy of Dutch’s book and read through it.
There are other ways to wring accuracy out of a ML, but his methods have worked for many here, including myself. I took two rifles through this process and was able to improve groups on both of them by varying the Ballistol to water ratio.
This also essentially creates a “dry” patch that will sit in there during a multi day hunt without dampening or fouling the powder.
Ballistol does have a smell when you are working with it, but it goes almost completely away on the finished patches. Having a single dry patch down in the barrel with a ball on top of it is not going to out you to a deer beyond the (relatively speaking) much stronger stink of yourself.
