I'm just putting the final touches on my mountain howitzer. I started it mainly as a large noise maker but I have to admit to a temptation to knock something over with a steel ball or whatever is handy The carriage is the pack type and the barrel is a 2.25" from Hern. I should have the tires on the rims next week and then it is "Look out, Betty!" However, before I pierce a charge, I would appreciate some advice from experienced hands on suitable loads for both noise and more serious stuff, plus construction of a practical sponge. I've mined this site and Buckstix quite a bit and have seen or shot smaller charges with salt and flour on top but don't see anything but disadvantage. Any help?
