I want to throw it out there that this is not my long range rig so all the broken shoulder deaf 338 or larger bore guys cool your jets! Seriously though I am build a 7mm WSSM not WSM but WSSM off of the 243 WSSM case simply necked up. I ordered a 9 twist barrel for it and was wondering if you fellas with lots of 7mm experience can tell me if it will shoot the 100 and 120 grain bullets well or will I have to stick to 140+ grain? According to quickload the 120 grain pills should come out at max around 3250 FPS and the 180 grain VLDs should come out at 2730. I am trying to make a all around gun that can ocassionally splay some p-dogs with tons of energy and have a gun that can be shot by my wife at a distance also. Thanks in advance. p.s. anyone know where I can get an inexpensive neck reamer .319"
