I came into some 1.5FFg black powder. I figured I can use it for plinking and casual shooting of my .54 rifle and .620 Barn fowler. Anyone have experience with it?
Anyone use 1.5F in their bigger bore flintlock rifles?

Probably worth picking a few pounds with the Goex stuff going on...
I had some Swiss 1 1/2 Fg. Couldn't ignite with anything less than a railroad flare. Well......almost. Gave it away to a bpcr friend.
I found this chart showing the granulation size for Swiss powder online.
Type Granulation Use
1Fg 1.2-1.6 mm Cannons, shotguns and muskets
1.5Fg .85-1.2 mm 45 Caliber rifles and bigger
2Fg .65-1.2 mm 45 Caliber rifles and bigger
3Fg .50-.8mm 45 caliber rifles and smaller, pistols
4Fg .19-.23 mm Flintlock priming powder only

I've got some for my 54 plains rifle and it shoots fine.
Herb on here swears by it in his Hawkens.

I use it in my Brown Bess and Charlesville. Works perfectly; both Swiss Cavier and Old Ensford.

I've used it in a .58 flinter and couldn't really tell any difference! A bit dirtier, perhaps.
Both I’ve used Swiss in my Colts and then in the flintlocks. The old ensford is $10.00 cheaper and I’m not that good to notice a difference in the big bores. The Swiss 2 f and 3f run cleaner unless I am imagining it both 1 and 1.5 both dirty the smooth bores up pretty well imo. The Swiss is very expensive forget buying from totw they are very expensive.

I'm going to give it a whirl in a few of mine soon and will report back. If guys can ignite 1FG in their fowlers, 1.5fg should go bang just as well.
Thanks for this! I shoot .50 cal rifles and just ordered some 1.5F (usually use 2F)
Some of each.

Olde Eynsford 1 1/2 F is my favorite powder. In my 32" .54 Bridger Hawken copy, 13 shots of 100 grains by weight averaged 1817 fps with 44 fps spread. 100 grains of Swiss 1 1/2F BY WEIGHT averaged 1724 fps with 120 fps spread. If you shoot more than 100 grains of Swiss 1 1/2F, it leaves a glassy deposit in the bore that must be cleaned out, at least in .54 and .58 rifles to my personal experimenting. I don't know about 62 caliber. I like OE 1 1/2F much better than Swiss 1 1/2F, but the Swiss will work well in .54 caliber rifles and larger with charges up to 100 grains.

Used 1.5 Swiss years ago in my Whitworth and Volunteer. Both .451. Worked great. No ignition problems with either CCI or RWS musket caps. Damn, I miss those rifles.
Reminds me how much I miss my grouse gun..

I finally tried Swiss 1.5F in my Kibler Colonial 58 today, with 4F swiss in the pan. My consensus is as long as you have a quality lock, you should not see or feel a difference in lock up time. The rifle went bang just as fast as it does with 3F or 2F. The accuracy was not on par, but I did not work up a load either. I loaded the same 80gr by volume as I do with my Olde Eynsford 2F. I imagine with proper load work up the 1.5F would outperform the Olde E in this gun.
