I have been having a ball shooting the old Winchester 73 I bought recently. I have been wanting to shoot the levergun silhouette match and finally got the opportunity yesterday. The rifle is very accurate and is made to shoot off hand and I expected to break 30 with it. As it happened I only shot 26. Part of the problem was that a new shooter walked up just before the relay started. He had no idea how to shoot the course and the relay started while I was explaining to him what to do. I didn't have time to get set and get into my rhythm and had to rush to get five rounds off. So I missed three chickens to start. I should have told him to watch one relay to see how it is done, but hind sight is 20-20!
The next nail in the "30" coffin happened on rams. I cast my first bullets for the rifle from wheel weight. I had to cast more for the match so I cast them from range scrap which is mostly black powder cartridge rifle silhouette bullets. I figured that would make a good alloy for 44 WCF. I had enough wheel weight bullets for one animal so I used them for turkeys since that is the smallest target and I used a few more for sighters. I had my ram sight picture all worked out for the wheel weight bullets and verified it before the match. The bullet hits just a few inches above point of aim at 200 meters so I hold just a hair up into the belly. The range scrap bullets hit considerably higher. They were over the back even when I held on the rail. To hit I had to hold under the rail. So anyway I missed to many rams to salvage "30"! Next time! Whenever that is since hunting season opens in three weeks and I won't be playing on the silhouette range for a while.
This whole 44 WCF thing is new territory for me. I have never played with a pistol type cartridge before. I usually use a 30-30 at around 1700 fps for the silhouette game. I don't have a proper 44WCF mold so I am loading a Saeco 441 at 256 grains with 6 grains Unique. I haven't chronoed them but they are really loafing along out there. It did heat up drastically during the match. When I shot sighters the temp was in the 70's. By the time I got to rams the temp was pushing 100. The thing is my turkey load was right on with the wheel weight bullets so I don't think temperature had much to do with the flatter trajectory although I suppose the velocities are really dying between 150 and 200 meters and any temp differences would be magnified there. I think most of it it has to be the different alloy. The range scrap is softer than the wheel weights since a lot of the black powder shooters use a lead/tin alloy. The other indication that things were different with the range scrap is that I had a wet lube ring around the muzzle. The muzzle stayed dry with wheel weight bullets.
I don't understand why the softer bullets shoot so much flatter and why I would have a lube ring with them and not with the wheel weight. The bullets are sized the same and use the same lube. I wouldn't expect 6 grains of Unique to bump them. The bore is rough in the old rifle and resembles sand paper more than anything else. It amazes me it shoots so well. It must be the slow twist that saves it. But, I digress. I am puzzled! The softer bullets seem to be sealing better but I don't know why.
