I usually check my brass for head case seperation everytime I reload. I usually stay within the recommended loads in the manuals, but with the Marlin action, I should be able to load to a higher pressure level than the 28,000. I imagine that the level is for the older 45-70 lever rifles, and is done to prevent law suits. I will have to try the PMC ammo, and see how it shoots before loading up any appreciable quantity of the higher pressure reloads. I'm sure that the 8 pound 1895 with a steel buttplate will give a pretty good thump to the shoulder.
