Loaded up a few test loads to run through a new to me marlin 1894c.

Loaded some Missouri Bullet 158gr RN Hi Tek Coated with 6.0 grains of Unique in 357 mag range brass. Accuracy was great and no leading. Also ran the same loads through a ruger gp 100 with great results. This load is a keeper.

Then I tried the same load and bullet but not coated. 12 rounds in on the pistol noticed decent leading at the beginning. Due to some other test loads I figured this would be best for accuracy, but a little much on leading.

Back to the rifle, I had 3 different test loads with 2400. Used Missouri Bullet 158 gr. SWC bhn18.

14.0grs - accuracy wasn’t great and no leading

14.3grs - accuracy was better but not promising. No leading.

14.5grs - about a 6” group at 25 yards no leading, but got to improve accuracy. Decent kick on all these.

All in all it was a good day. Just got to get something going with 2400.

Before I left I ran another load through the GP 100 to test the accuracy.
38 special brass with Missouri Bullet 158 grain RN loaded with 4.1 grains of W231. Accuracy was good but got leading down the barrel. This is my go to for a light target load out of a smith 686 2.5”. Looks like the ruger doesn’t like it as much.
