I am trying to decide what powder to use for full power heavy loads in my GP. First, I am looking at using Cast Performance 180gr gas checked bullets, but I can't decide which powder is best for this application.
H 110 seems very well established, and somewhat of a standby, but Lil' Gun has even higher published velocities at lower pressures. However, I have read the Lil' Gun will eat up barrels. Any truth? Also, do these powders need Magnum primers to work best?
