Yeah, I used to have a bore light that went MIA then the other day I got a CVA one at the local gun store. However, when I got it, the battery was dead so I returned it. Having a new to me TC Hawken .50 percussion rifle coming in, I needed to check the bore before my 7-day inspection was up. I have a ton of .45 ACP ammo around so I just dropped a loaded round down the barrel nose first and used the base to reflect the light from my flashlight. I found the bore was in good shape and she shoots good so I'm happy.
