What do you all put in your muzzleloader barrels to keep them from rusting? Ive been using bore butter inside the barrel and wiping the outside down with wd-40 and my dad tells me I should be using oil inside the bore and the bore butter on the outside. Just wondering what you all use

Listen to your dad. He sounds like a wise man. It's oil for me.

I use mainly rem oil on the inside and outside. did the bore butter on the inside for a month, accuracy went down the tubes.

bore butter moved to the role of patch and conical lube.

Gun oil...

Bore Butter was made and marketed for sidelocks...IF it has any real value it's as a patch lube...
Frankly, there are better patch lubes avaliable...

Bore Butter has no use in a inline...

I have used nothing but BB for years on the inside of the barrel and the outside of the barrel, I even wipe the outside of the scope with it. During rain and snow it actually repels the water. I never noticed any accuracy problems but anyone that has I would like you to post your findings of your likes and dislikes of BB. I would appreciate it. Im willing to change, if change is good. I also ordered 2 bottles of the Montana XTreme to try out. I have always been taught to NEVER use any petroleum based oils in a ML barrel. Have I been told wrong?

So I guess Im wrong using BB?? I just purchased 4 tubes from Wal-Mart, discounted.

Both of my muzzleloaders are sidelocks. What is wrong with BB in the bore? I use it to lube my patches and maxi-balls during hunting season (use spit patches during off season).

If bore butter works for you, then by all means use it. I personally do not want to use it. I would rather my rifles be protected by a quality gun oil. One of my favorites is Birchwood Casey Sheath.

breechplug,

from sub 1in group at 50yrds to 3in groups at 50yrds, this was over a year ago, have not idea where I filed the pics of the target.

here one use that I never said, I have used bore butter as breech plug grease, the plug on my knight usak came out great. 20 shots no loosing, very little work to get it out. just a pita to clean.

What is wrong with it? Its ok to put on the outside of your barrel why not the inside? oil is a rust preventitive isnt BB?
