Interesting information. I've not 'worked' with the Roland, yet, but have worked with several different cast 255gr'ers in the acp trying to get to te 900-1000fps threshold w/o sending my slide back into my forehead. Feeding hasn't been a problem with the swc's that I'm using in my 'stock' government model. Sounds like the Rowland may get there easier with less effort than experimenting with the 255/acp combo.

BTW, Hank, if you're coming to the OPHA meet in Woodward we can visit some about what you've found out thus far.
