Well, my new chrono is screwed. I managed to clock 1 round, wind took the chrono to the concrete and now it’s toast.
240gr Berry’s Jacketed Target HPs
23.8gr Lil’ Gun
Henry Big Boy 20” Barrel
Unfortunately, those are about 400fps faster than max velocity of these bullets. After I clocked them I went and double checked. Some bullets like 45-70 and 500 mag have a 2000fps max. These only have a 1250fps max. Going to have to do this over again.
The chrono now reads 2444, 2424 and 2442 instead of the 1600 range. I double checked with the 45 Colt loads I just tested. The chrono is screwed.
