Just for something to do since I didn't muster the will to drive an hour to the range today I thought I would post the round ball sight in target for the GM .50 from yesterday. In case you're wondering, the first of the 2 numbers by the hole is the shot group after cleaning the barrel. The second number is the number of the shot or shots fired after cleaning the barrel. So a 3-2 would be the third time I cleaned the barrel and the second shot taken after cleaning it.I only have a few XTP's so I think I'll try to find some today. It seems I cut the target range off with the camera. The range was 25 yards using 80 gr. fff goex and a patched round ball of course. I don't know what the thickness of the patch was. They are like over 15 years old.

I just picked these up at a local shop. There should be enough here to get me sighted in with them.
Wow! I'm getting better. That looks like a pretty good picture.
Now if I could figure out how to reduce the size of the picture.

Be careful of old patches. They can really play havoc with accuracy. One reason I start with new cloth and cut from the muzzle. You want a stink, take an old lubed patch and put that in a sealed container and forget about it for a year. It turns black and don't open that lid. The stink will knock a buzzard off a ... well you know.

Those XTPs should shoot well with 85 grains of powder..
