Bob, I have none with that particular cartridge but have fiddled with it in small capacity cases such as the .25-20SS and my invention the .30 Sneezer (necked down .357 case). It works well enough. Simple load for my cases is fill them up to about bullet base depth, add a .030" wad, compress and seat the bullet. They seem ambivalent about the use of duplex loads, unlike the larger cases. One small benefit of that is less fouling.
