Is anyone aware of a source for lighter hardcast gas-checked bullets for the .375Win? I am presently shooting 200 and 220 grain jacketed bullets above 39 to 40 grains of AA1680 or AA2015. I would like to shoot a gas-checked lead bullet but it seems they are all on the heavy end, 250-260 grains. Any .375 shooters out there that can help? Also, have any of you taken this caliber to its potential? Like the .35Rem, the factory loads seem to be well below the limits of the action.
