4F Additive called "Raincoat"

[Deacon4]

Any of you feller's ever use an additive for primming powder (flinters) called "Raincoat"? It was on the market a couple of years ago. The white stuff you mixed with 4F and helped keep it from soaking up moisture while in the pan.

I don't know if it's the same stuff I have but it sounds like it. I can't remember the name but I bought it several years ago just for what your talking about. A real fine white power suppose to help keep you powder dry. I still have the bottle but the label is peeled off. I stopped using it because I noticed that it slowed the powder burn rate down in my pan. It would cause a delay in my flintlock. You can use it on other things as well like fletching on arrows if you use feathers. I've tried it on differnt rifles and all had the same delay.

Heard about but wouldn't trust it...I just keep the lock up under my coat close to my body in damp weather and refresh the prime every 30-45 minutes under those conditions

Probably didn't do this right but we had a discussion about this some time back. I use it in bad weather and like it.

This stuff comes and goes from the market. Back in the 1980's Fuzz Fetterman had some out.

Basically it is micro-pulverized silica. Sold to industry under trades names like CabOSil.

It really does not protect the powder from moisture. Simply masks the things that indicate the powder picked up moisture in the lock pan.

When you coat the powder with it you are simply dusting the grains surfaces with a fine dusting of silica dust. It does not prevent the surfaces of the grains from picking up moisture.

Graphite coatings on black powder do not prevent moisture pick up by the powder. It simply keeps the grains from sticking together when they do pick up moisture. So when treated with the ground silica you are simply giving the powder grains yet another coating of something that simply hides any moisture pick up by the powder.

I agree, bought some from ole "Fuzzy" years ago, used it a couple of times, it slowed my "fire" time more than I liked. Good ole fashioned cows knee, or keep'er tucked under your armpit and refresh liked suggested.

used it for a while, never saw much difference..when I switched to FFF for priming as well as loading, I got better ignition in damp weather, and in dry as well....if it is pouring rain, I am inside, looking out at it...Hank

Besides....Dan'l "didn't need no stinking raincoat" to keep his powder dry

I have used it for 20 years and I like the stuff. The only time I saw it delay anything was when mixing too much of it with the powder. I use about 1/2 teaspoon in about 2 oz. of powder and shake it up in a bottle and then put it in my pan charger. It is was originally a dry fly dressing. RMC Sports also sells it as Fletch Dry for real feather fletching.

I've never tried it. I've read on this site that 3f drws moisture slower than 4f. This weekend i got to expierement with it. I went to mu folks place down south,and took my rifle with me to get a little shooting in. When i made it out to the woods its was flat pouring. I mean you couldn't see much past 50 yards in open field. I'd loaded with 3f and primed with 4f. Then went for a walk in the woods. I kept the lock firmly under my armpit to protect the pan. After awhile i decided to shoot at a stump. Well i cocked the piece,squeezed the trigger. It sparked and that was it. I checked the pan. It was dry so i tried again. Same thing. I did this a couple more times with the same results,so i blew out the pan and primed with 3f from the horn. Went off first time.I stayed in the woods and tried it a few more times with 3f didn't have one misfire.I guess it's not really conclusive,but it convinced me there's somethin to it. I didn't get to stay out very long. It started lightning,so i figured i'd better get back. The trees down there have a bad habit of beeing struck by lightning. Just my 2 cents
