[QUOTE="284stak, post: 362878, member: 8891"] I had my smith build a 338 imp Lapua on a chrome moly 700 action using a PTG bolt w/m-16 extractor. I am using 98 gr of retumbo in a 29 inch barrell. The chrony reads 2900 roughly, but drop tables and a bc of .771 on the 300 SMK gets me at 2850 fps for my drops. I have no way of measuring the actual pressure I am generating in the case, but several threads have mentioned that if you keep velocity under 2950 - 3000 with the 300 SMK - you should be safe. I will say that my initial plan was to build this on a 338TAC action, but after a yr wait for the action that was supposed to be 6 mos - I went with the 700 action as I had a stock laying around inletted for the 700.
