You may want to check with T/C before loading the Encore to max Ruger loads. The Ruger is a lot stronger. Try a few of the heavier Marlin loads and see how you like them.
My understanding has always been that the Encores were limited to the loads listed for the Marlin. However, opinion vary on this entire issue; Trapdoor vs Marlin VS Ruger.
Compare several loading manuals and you'll see that they don't agree either.
