Home Forums Hunting & Shooting Muzzleloaders 1970s powder VS SWISS

Well, I bought this oldie back in June and finally put it through the hoops! Today, this old powder, put swiss powder to shame!

Doc White made many fine rifles, and as it turns out, he also made one hell of a black powder as well!

Green River Sporting Powder 2fg, 1970s.

Ardesa Mountain Rifle .54cal with 1:66 twist
.020" patches ( alcohol-Murphy oil soap lube mix ) .530" round balls. No swabbing was needed.
70gr Green River 2fg
50 yards





Swiss 2fg, same patch, lube, ball size, distance.

Red dots indicate the 70gr 2fg swiss 3 shot group.

Interesting. Never thought a variation in powder type would have that dramatic poi shift at a mere 50 yards.

I’ve been using 80gr of Black MZ in my 54 round ball shooter. I guess I better stick with it, though Ive thought about reducing 70.
