Just got a chronograph and tested my 87grn loads in 25-06.
According to hornady book should be getting roughly 3200 fps, but when tested only getting 2850.
Heads are set out to standard oal 3.115 and groups are good.
Im using 53.3 grn h4831sc and fedrel primer with winchester brass
Have i done something wrong.
Thought i was getting somewhere with my loading
Just thought as well, set chrono 2m away from muzzle
