I worked up loads for my new rifle early this spring and everything was fine with no pressure signs. We went shooting the other day and my rifle really kicked and we can’t get the bolt open. What happened?

This is an occurrence that usually happens when a near maximum load is worked up during cool weather, but when shot during hot weather, is over maximum. As powder heats up in a contained space, it ignites easier and faster, building pressures. Take into consideration the temperatures you will be shooting in and load accordingly. Better yet, work your loads up in those temperatures. Keep ammo shaded if any way possible.
