My understanding of lube on conicals is that it is to soften fouling of a series of shots after the first. I have heard that it helps create a gas seal but this seems somewhat far-fetched. I have 100 conicals that have two grooves without lube in them. Can they be used "as-is"? If they must be lubed is there some recipe I can make at home and apply manually? Last question - I know some people use button wads over powder with conicals but I have heard a 100% cotton ball can work. Any thoughts on that? Thank you in advance.....
