so i have a 1995 browning A bolt BOSS in 300 win mag and am shooting federal factory ammo. blue box stuff 150 gr soft point. and the problem is that after a shot the bolt will lift fine but will not come back. a smith said head space is great so its ok there and it works fine empty but after a shot the bolt lifts fine just pulls back hard. chamber is clean clean clean so im lost
the primers are not out but they do seem a little flat. the smith looked at the empties and said they may be a little hot even from the factory(?). no one looked at chamber with a scope. what else. thanks very much
You may want to try another brand or different lot of federals.Even though their factory rounds it could be a hot batch.Even if the head space is correct it could a tight chamber if it is your primer won't show any sign of pressure.
Cartridge extraction is a two step process. The primary extraction initially pulls the cartridge free of the chamber allowing the second part, withdrawing the bolt rearward. If the bolt rotates to the fully open(unlocked) position but the bolt cannot be drawn rearward there is insufficient PE and/or it's timing is late.
