Hi all,
I finally got around to chronographing a hornet load I settled on. I am using PPU brass and 45 gr Sierra hornet bullets with 12.6 gr of Lilgun. When working up the load 12.6 gr was most accurate and I started running into sticky bolt lift before I ever reach the 13.0 gr max listed in several sources. Anyhow, at 12.6 gr of Lilgun I got an average muzzle velocity of 2993 fps out of my 22" barrel, which is about 200 fps faster than the velocity listed for the 13.0 gr max load for the 22 hornet out of a 24" barrel.
I have heard of fast barrels, but this seems too good to be true. I am guessing that my load must be way over pressure. One of my fired PPU cases will hold 13.8 gr of water. I am wondering how this compares with most hornet brass? Max loads with Lilgun are suppose to be compressed, and 12.6 grains doesn't look like it will be compressed. I am guessing I need to start chronographing at the minimum 12.0 gr and see when I get close to the 2750-2800 fps range.
Any other thoughts?
