Hi there. Am curious about your comment re not using gun oil in a black powder gun ever ---- so what do you use as a replacement ?
I look forward to your advice .

Ballistol to clean. I use 2oz of the liquid in 14 oz of water to make my "moosemilk". You may spray it over the entire gun as it was developed to be used on both wood and metal by the Germans for the military. Then use a product by the name of EEZOX for your bore and other metal parts. I've used it for several years now since John Boy did a test on the Jersey shore.
Ive shot the 44wcf with BP since the 70's. John Kort and I have exchanged ideas for several years and he is a very nice man. I also designed a bullet for the 44wcf on the Accurate bullet designs. Mine is listed under the name of Fairshake which is my SASS name.
John shoots a long bbl Marlin and I shoot a Uberti 73 with a 20 in. bbl. He tested my bullit and had good results but the lube was not enough for his longer bbl. Marlin after a few magazines loaded up.
I will say that you need to change your bullet lube and I agree that you need a larger charge to provide the upset you need. I shoot 37 grs with my 210 gr. bullet

For someone who shoots an A.Uberti 1866 in .44WCF, I pour in a charge of 3Fg until it reaches the mouth of the case. I then put a card wad on top of the powder and compress the powder until I can seat my bullet. a Big Lube .430 200 grain slug from Springfield Slim. The bullet gets a good crimp. I prime the case, before all of this, with a Magnum large pistol primer. I hope this helps. You might want to slug the bore to make sure you're using the right diameter bullet.
