Re: 338 Lapua

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.

    Re: 338 Lapua

    I completely understand your concerns as smiths not to want to risk a lawsuit. When I do build my rifle it will either be just the lapua or improved havent decided if dealing with a wildcat cartridge is worth the hassle. I plan on going with a ptg chrome moly bolt. what would be the advantage of an m-16 extractor over a sako? 284stak i would really like to see a picture of your rifle if you get a chance. Any more input would be great

    What I can't figure out is, where the hell do you guys all get the money for these builds??? I'm guessing that none of you work for the county. LoL I'd sell a damn kidney for a 338 AM and remove it myself for a NF scope!

    Would be happy to send a picture for you - but have not figured out how to on this site. If you want - send me a PM w/your email and I can email it.
    I have a sako extractor on my 7-330Dakota and the m-16 extractor on the 338 is quite a bit beefier in appearance. I can email both bolts to show the difference.
    My preference would have been the 338TAC action, but have been happy with the way things turned out.
