"When the bolt doesn't move it is hard to feed in the next cartridge. "
REALLY???
"And this happens quite a lot" Are you KIDDING??? Do you actually reload and shoot rifles??
This is silliness at the extreme.
If the load is a few grains less, it cannot cause the bolt to stick, and a stuck bolt does NOT effect the feeding of cartridges from the magazine.
Did you even read my first post? The advice was to not load full bore max loads for hunting.
I WAS ADVISING NOT LOADING MAX LOADS.
