If you go to strictly mounted use, you can even load it a bit longer and get back some of the lost powder space.A 200+ grain "eco-friendly" bullet would be extremely long for caliber, and likely require barrels with a faster rifling twist. Even loaded long, a lot of powder space would be lost. Plus, a long loading might require gun modifications, something to be avoided, if at all possible.
