does this factory load have too much pressure?

my rifle is a remington 700, 26 inch barrel.
the round is factory 7mm rem mag, hornady 154g sst superformance doing 3150.

i first wondered this when my bolt was a bit sticky to open once i fired the round.
the primers are a little flat and some cratering.
maybe the pictures will tell the story, i do like the round but want it to be safe for me and the rifle. i know nothing about reloading.

Re: does this factory load have too much pressure?

Just looking at the primers I would say NO it does not have too much pressure. If you are referring to the protrusion around where the firing pin struck I would say that you have a little large firing pin hole in your bolt face or a week firing pin spring. This will cause that ring. It is not too much to be worried about unless you start to have issues with hard bolt lift from where the metal of the primer sticking into the firing pin hole starts to bind things up. You can have your firing pin hole bushed by a good gunsmith to correct this. Too much pressure would flatten the outer edges of the primers and yours are nice and round.

Also you did not mention what the weather conditions were when you were shooting. If it was hot and your ammo was warm that could raise the pressure and cause the slight hard bolt life. I would not worry about it unless you started having really hard bolt lift on every round. That 154 gr Hornady bullet in the 7 mag is probably the best deer killing bullet I have ever used in that caliber. I know a bunch of people that use this bullet in the bean fields on NC for deer.

They look fine as far as pressure.

i just re-read this. the bolt is a bit sticky in all weather conditions. iv fired at least 70 rounds. it seems to be even harder to extract the case if you dont do it straight away once iv fired.

again thanks for the replys.
