Anyone casting these for close range plinking and possible small game hunting? Hate to waste any material when it can be avoided and would be sweet to pop some grouse with a 30 cal using a projectile weighing little more than your run of the mill grouse getter 22LR bullet. Figure OO buck can also be used in 8mm. Couldn't find much info on this online so figured some here may have done a bit of testing and wouldn't mind sharing some results.
