I use dummy rounds in live fire and dry fire. I typically purchase these from Amazon. The bright orange tip is helpful for confirming they're dummies, but they weigh less because of the plastic "bullet" and they're freakin expensive.
I can make a bunch on my XL650 for much less expense. I typically use Bayou or Everglades plated bullets for my live rounds, and I'd prefer a completely different color or shape for the dummies. Any suggestions?
