IMR 4198 in my Trapdoor.

I finally loaded 2 rounds of smokeless powder to test, for my 1884 .45-70 Trapdoor that was made in 1887, using 29 gr. of IMR 4198 behind Bullshop's 500 gr. Government cast bullet, with a 2" x 2" piece of single ply toilet tissue pressed inside the case with a pencil eraser, to hold the powder near the primer, behind the bullet. I recently bought an old Ideal hand loading tool chambered for the 500 gr. round nosed bullet, so, I tried it out. It worked perfectly. I only have a very limited area to shoot, as the high water levels in Lake Erie have pushed the creek behind my home. half way up into my back yard. I set my target against a tree at the edge of the yard, that my rangefinder said was 41 yds.  I stood in my garage doorway, using a stepladder for a rest. Aiming for the center of the bull, my first shot hit 5 1/2" H, & 3 1/2" left of POA. The 2nd shot, POA was at bottom center of the target, & it hit 7 1/2" H, 1" above center of bullseye. The recoil was approximately about the same as shooting 68 weighed gr. of 2F Goex with the same bullet. As for cleaning, after firing 2 shots in 49 degree temp., the first patch came out black, slightly tacky & moist. The second patch was not very bad at all, & the 3rd was almost clean. I think Daniel lubed them with Lotak, for BP. Now, I'll load about 25 rounds for deer season, hoping to only need 2 or 3. We are allowes up to 6 deer, only 1 antlered, & no more than 3 deer in any 1 county. If I get 1, that will be great, & 2 would be a bonus, that I can share with friends that aren't able to hunt anymore.  I hit & ran over a doe last Saturday night, but I couldn't find her until the next morning in a ditch with bad water covering most of her, so I left it for the animals.  I tried to add pictures, but it said that the file is too big.
