White Muzzleloading Systems model Bison G series,cal .504 Blue with black synthetic stock. Sling swivels,scope blocks,adjustable sights,in line percussion cap ignition. Bore looks good with deep rifling and only a few light spots of fouling.
I do not know how that person ever looked down the barrel at the rifling. That rifle was filthy. I would have been embarrassed to sell a rifle like that. I broke the rifle down and cleaned it all. The crud that was in the barrel worried me at first. I really had to work, to get the barrel clean. There was a lot of grease and fowling, with a little orange rust I might add, in the barrel. The breech plug was worn a little, fowled badly and not even open and unlubed, but I got that all cleaned up. The trigger I do not think had ever been removed and cleaned, so we got that done. When I finally had it clean to my standards, I headed to the range with it.
With the short bull barrel and the synthetic stock the rifle looks pretty cool I think. The barrel is much different then that on the Ultra Mag. The crown in the end of the muzzle is very strange looking. Probably made by a different company. After I got the barrel clean, there was only very light marks in the barrel. It actually looks in good shape. The trigger on this rifle is excellent. It breaks clean, no creep, and if I had to guess, I would guess it at four pounds.
For some reason this rifle will not take the RWS Dynamite Noble caps. The first hit from the hammer sets the cap and the second fires it. It got worse as the rifle fowled. So you have to keep cleaning the nipple good. I finally went in and opened my CCI Magnum caps. They were much better, but still not the answer. As long as the nipple is clean the CCI do a great job.
I tried Triple Se7en 3f, Pyrodex P, and Goex 3f with and without wads. I shot Bullshop .504, Bullshop .503, and some UC Short Mags sized down to .504 caliber. The best loading were the .503 but if the bore is clean the others load fine, you just have to knock them down with a short starter as the barrel fowls.
The other thing I discovered right off the bat was, this sight was set to shoot as high as possible. I was only at 50 yards, but when I aimed at the dead center large bull, the hits were very high, and a little to the right.
Group #1 is a combination of .504 & .503 BS 460 grain with and with out wads, using 70 grains of Triple Se7en 3f.
Group #2 is after I thought I lowered the rear sight enough. I shot, then adjusted to the left but went too much. So I then put one center of the two. Point of aim was the upper left corner bull.
Group #3 is I lowered the sight more and adjusted back to the right a little too much. This was shot with 65 grains of Pyrodex P and .503 BS 460 grain. A rather tight group this time. Point of aim was the upper left bull.
Group #4 I was aiming again at the center bull. This group was an assortment of using Pyrodex, Goex 3f, and Triple Se7en again. It seemed to be holding pretty good.
Group #5 was to the right of the bull on purpose. I wanted to shoot at the 3 o'clock position of the bull with 65 grains of Goex 3f and the .503 BS 460. It did pretty good actually.
Group #6 was shooting Triple Se7en 3f without a wad. I was shooting the UC Short Mags and my home made lube. I aimed at the bottom of the green bull at the 6 o'clock position, so I was pretty happy with them as well. They loaded kind of hard though from using the Goex, so I had to swab the barrel.
Group #7 was shot with Pyrodex P and some wads using the UC Short Mags. I was shooting at the lower left bull and was surprised the wads made them hit low and a little to the right.
Group #8 at the lower right bull is with the Pyrodex P and the .503 BS 460 grain. I was kind of pleased with that.
Over all I think this rifle is going to be a shooter. I put a lot of lead and powder down range today. Recoil is not bad at all with this little rifle, and it is really well balanced. The rifle cleaned up fine, but I did take some J-B Bore Paste and scrub the bore today. The Bison looks much better all cleaned up now, and in my gun rack. I think the next time to town I will get the Nikon 1X20mm scope for it and use some Warne QD rings.
