Roundoak,no,I did not consider throat dimensions when building the 7x57. I have a CZ 550 that has a long throat and a Featherweight with a much shorter throat. Figure the one pictured will be closer to the Featherweight,but will find out this weekend. All I've done so far is get it on paper at 25 yards,will take it out to 100 this weekend sometime.
MD,I have two other 7x57's that will shoot 140-175 grain bullets,just wanted one that'll handle the 140 grain class bullets. No logic behind the decision,just wanting a 7x57 that'll shoot a 140 grain bullet.
You probably already know this you can get an idea of the throat length by inverting a flat base bullet into a case trimmed to 2.225" then insert into the rifle and close the bolt.
