This has been a fun test and I learned a lot. Thank you for your reply.
You're most welcome, I too have been interested in ballistics and bought a chronograph sometime in the 80s or 90s and it required building a sawhorse of sorts and positioning two timers exactly 10 feet apart, which recorded the time that the bullet crossed over and then I referred that number to a chart. I believe it was called tepco or something like that, I still have it though I bought an upgraded Chronograph that will record the speed of arrows and bullets some 20 years ago. The first one I had was so bothered by sunlight that I fixed up 25 Watt DC bulbs that were 12 V above each timer and did most of my testing at night. As far as I know, I was the only one in this area that messed with it that long ago. It had three different charts, and it would run from 1000 to 4000 ft./s depending on the spacing of the timers. Once I was satisfied that my hand loads were equal to factory loads that I chronographed, I kind of quit messing with it, but just this summer I did check some on a 50 caliber Flintlock muzzleloader. I have a 45 percussion, that I wanted to test, but with that bridge out I probably won't make it. The bridge is supposed to be fixed by the end of October, and depending on the weather I might get it done. I'm in the center of Montana and it can get tough sometimes. I really am curious how you make out with what you're doing, I never measured mine enough to see how it deviated between shots. I didn't compute it back to the muzzle either, as I was only interested in what I could achieve for like 75 yard shots. Keep it up, and I hope you're wife does well in her upcoming surgery. My knees are still original, but both shoulders are fake.Thank you for your reply
