I'd say try it and see. From my own perspestive, in a '96 Ruger, I had no problems using plain base bullets, or gas checks for that matter at full power. I made my selectuion based on accuracy, and a Plain Based 240 grain Kieth bullet from a Lyman mold did the job. You may have to play with your alloy to avoid ledding with the plain base. I used water dropped wheel weights myself.
