comparison testing of JSG 3f in Wolverine
 

Since FG has had so much fun testing JSG 3f and I have two jugs of it (for shooting black powder revolver) I decided to test the powder in a Knight Wolverine.

The rifle is a .50 caliber Knight LK 93 Wolverine with a stainless steel barrel and a 1x32mm Traditions ($50.00) scope on it with Tradition steel mounts. I know this rifle likes 90 grains of Pyrodex RS and a .430 .44 caliber Hornady XTP with a green harvester crushed rib sabot. I was using RWS 1075 caps.

As always I prepared the rifle by cleaning the bore with alcohol. I then dry patched it to remove any oil. I also popped a couple caps through the breech plug.

I loaded 90 grains of JSG and the Harvester XTP mentioned. The first shot was a dead bull. I was impressed. The rifle seemed to have a good stiff recoil with that load. Since I read that you do not have to swab with JSG I did not. The more I shot, I felt that might not be such good advise. The bullet and sabot at the muzzle was extremely difficult to start into the barrel. But the accuracy was pretty good actually. #2 for some reason jumped to the side, but 3-5 were real good. Then for some reason #6 just took off.



The strange part was I really felt good about all the shots. I was using extreme pressure when seating the sabot on the charge (like told to do) but there was some definite issues going on in the bore when I was loading. I could feel fouling but not see it. As most of you can understand, when the sabot went down the bore, it did not feel right. Not like when I swab the bore.

But I blamed #6 on myself and decided to test it against the regular powder I use which is Pyrodex.

So I took Windex and cleaned the bore of the rifle. Almost immediately I noticed a very dirty patch come out of that rifle. Not at all what I expected from JSG. I kept swabbing and finally the dirty patches stopped. I even took the bolt and breech plug out of the back of the rifle and visually checked to make sure the rifle was clean.

I then dried the rifle well, popped a cap and loaded with 90 grains of Pyrodex RS.



Shot number 1 was right where it should be for a 50 yard target. To be fair to JSG I did not swab the bore and fired two more shots. I could have loaded a fourth but to be honest, the rifle was very fouled and I knew it. So I swabbed and shot two more which were right in there with the group. But the batteries on the camera decided to die then and there, so all I can show is the first three shot.

Then I decided to call it a day. When I took the rifle apart to clean, the trigger fell apart in the rifle. I located a spring, small pin and side plate in the floor (just lucky I clean them on a carpet area) but I have figure out where they go and how to get them there. Maybe I will send the trigger out to Knight. Test their new customer service.

My overall impression of JSG in a rifle... it works good. Is way to expensive for shooting in a rifle. And I will keep it for the revolver.

Another fine report Cayugad. :cool2:

Not too surprised with some of your findings. I've had pretty good results accuracy wise with JSG 2F with patched balls. Also, it was pretty clean burning. But I haven't had as good results with sabotted bullets and didn't think it was any cleaner than GOEX when shooting them.

Can't say why - but that's been my experience.

Well I got out some of the other Timney Triggers I have and saw where the parts go. There might be something still wrong, but I put it all back together and it works. That is the main thing.

That's good. If it worked for a few test trys it's probably good to go.

Even if it fails at some point (on the range - not hunting) it's no big deal because you could probably find another gun to shoot if you looked around real hard. :happy0157:

Good shooting Cayugad. I think with more load experiments you'll get things to come together much tighter.

You're right about the muzzle being tight. For some reason, when i had that traditions evolution inline, #11 caps always gave me a reverse crud ring. I got it at the muzzle rather than at the breech plug end. That was with pyrodex though.

Why dont you break out one of them traditions sidelocks and give the JSG 3f a go with some round balls? I really like this stuff in the sidelocks.

Well I will try the Penn Hunter that has a 1-66 twist. It is a great roundball thrower. Although they are talking thunder storms today so the shooting might be put on hold.
