I took it off last night and it sounded liked a $99. walmart rack sys without my invention,unlistenable.I'm using 3006 all copper brass military ammo,will experiment with more readily available all brass cartridges.They must have pointed tips,I tried remington lead tips,worthless.You can get started by getting 8 round m1 garrand clips,cheap,when you pack the ammo in press down on flat surface so bullets rest square on top of cabinet.8mm 8 by 57 js mauser 196 grain fmj ( full metal jacket) fits in m1 clip for mark as such as not to blow up m1 by mistake.Not quite as good sound as 3006.I found a brass ashtray at garage sale.To get stated place m1 clips length wise from corners of cabinet aiming toward center. If you own b100 you have no idea what a phenomenal sounding thoroughbred race horse of an amp you own. I'll keep you posted on my test results. Playpen.
