I’ll never challenge Ron on the terminal performance testing front but I do have some results to share.
Background: I have a New Mexico Elk Tag on my pocket. It’s a difficult to draw unit and for the first time in my life, I’ve contracted an outfitter for my Son and I. Since this is a open canyon country, post rut hunt, I’ve been asked to be proficient to 300 Yards. With practice, Im becoming more comfortable at the long ranges. I will have two guns prepared. Gun 1 is a Knight Super Disc 45 shooting heavy lead. I have no worries on terminal performance if I do my part. Gun 2 is still up in the air. I have my .52 Knight Disc dialed in, shooting MOA to 300 but based on the below, it’s back to the drawing board.
No matter what projectile I use, speed drops considerably after 250 yards. I decided to test my current bullet options in ballistic gel at speeds I’ll have at the longest shot ( 1200-1300 FPS ).
The gel was mixed at 1 lb of beef gelatin to 1 gallon of water. I think this is about 12% concentration. 3 gallons total. I poured it on to a 6” x 6” x 23” brick. I then built a containment box out of scrap lumber and old paper brochures I had laying around. The containment box should had been built better but I did it’s job as I recovered each bullet fired. I added a chrony to the front for accurate speed capture.
I’ll post the results in subsequent threads.
