Good day.
I need some info on CFE 223.
I loaded CFE 223 on my .303 british and took it to the range to do some load development. I loaded from 42.8gr to 44gr, the max charge on the website. Everything was going well. I got close to the speed that the reloading manual claims right up to 43.7gr where I had a drop in speed of 60fps and then the same with 44gr.
When I shot the first shot and saw the drop in speed I took some factory ammo and shot it over the chronograph to test the chrono but it gave the same speed as claimed on the box of ammo
My speeds where as follow.
42.8gr: 2555
43.1gr: 2583
43.3gr: 2601
43.7gr: 2542
44gr: 2571
Is this drop in speed a pressure sign? I had a real nice group at 43.7gr but I do not tust the sudden drop in speed.
