1970s powder VS SWISS

[FrontierGander]

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.

Some beautiful grouping from a beautiful rifle!

Better go easy on that Green River...ln case you ain't heard the plant blew up back last century and hasn't been made since.
BTY, you either need some serious load development or a better rifle if that's the best groups from rest you're getting at fifty yards.

rifle shoots awesome with gearhart owen, green river, scheutzen, goex. Ive never been able to get swiss to shoot accurate in any of my rifles. Nasty sticky fouling, even with a spit patch. Friend has a 58cal GRRW Hawken and i loaned him some swiss 3fg. He complained about the sticky fouling too.
