Thanks to all for the replies. Big 6, I have a bunch of powders. I have Sr 4759, Re 7, 4227, 4064, Varget, 3031, H4350, IMR 4350, Re 15,19,22,25, 7828, H and IMR 4831, and I expect several others that don't come to mind right now. I tried the 4759 first and could not hit paper at 25 using the 250 gr SST. So I went to the 5744. SOme shots were better anyway. I have a bunch of powders but what I am running out of is time. A week from tomorrow I am supposed to be in the woods. I can shoot tomorrow and maybe a bit Sunday. Saturday is tied up. If luck and weather hold maybe after work next week but not many rounds as the days are getting shorter.
The 300 gr XTP's came today. I will use them with the MMP 24's that I have. I have the short black's and the three petals on the way. May be here tomorrow. I will look for the harvestor Sabots at our only outdoor store tomorrow. I doubt that I can find a can of N -110 in the next few days. Do the boys in G'boro have it? I have a son that will be passing through G'boro next Friday. He may be able to get me a can.That will be too late for the Friday hunt but maybe for the next weekend.
42 gr of 5744 is the best shooting load I have been able to come up with so far. We will see tomorrow what it will do with the 300 gr XTP.
A 5/32 drill bit will not go all the way through the breech plug. I tried a 5/32 and it scarcely cleared the threads on the vent liner. A 5/64 will however. I ran it well in there and seemed to be against metal. I put a new vent liner in it about a dozen rounds ago. Cleaned the rifle twice since then with Hoppe's #9 and break free CLP. I think a fouled breech plug was part of the problem with the Barnes 290's I shot last weekend at the hunting camp. The last round I fired missed target by a full 4 feet. I watched a branch fall in the woods way off to the right. I found that the breech plug only had a very small opening and I found unburned powder in the barrel. From now on I will treat it like it was any other muzzle loader and disassemble and clean well after every range session.
Do you guys have contact info for Henry and Bill? How about a street address? Thanks
I am using a Hoppes rest and forend and rear sand bags. It has worked great for most of my other rifles. Yes the nut behind the but can have his problems. Some days my 50 yr old eyes don't work as well as they used to. My groups sometimes are 2 -3 inches with a 3/4 inch gun and load. That would be entirely acceptable to me for hunting accuracy with a muzzle loader at 100 yards. This 3-4 feet thing makes me weak in the knees when thinking about shooting at a live game animal. I will beat that or I will stay at the camp and wait on centerfire season to open. I will post tomorrow with my results. Thanks to all for your help and suggestions.
