Re: savage 338 lapua

my 338 Lapua is running 2635 fps with a 280 grain bullet and 82.4 grains of retumbo, am seriously considering a rebarrel to get another 200 fps.

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

    None of this makes sense unless the chamber isnt to spec or something. Im running 2850 with 12.3 gr more powder(YIKES) than a lapua in an edge. Those two are considered to be close to ballistic twins so something is OFF and it should be fixable. Id sure like to know how tight that chamber is. The only logical conclusion is that the chamber is tiny and is causing low vel/high pressure.
    Be nice to KNOW a once fired cases H2O capacity and dimensions next to a custom or even rem once fired case. That should be a redneck/DIY way to look into the issue.

    If someone with a non savage 338 Lapua using Lapua brass could get a h2o capacity measurement and post it i could compare it to one of my fired cases. Toddc, would (should) getting a couple threads cut off then rechambered fix the small chamber problem if that is the issue?

    Its a savage. If the chamber is too narrow yeah needs smithwork. If its just real tight depthwise then just adjust it at the nut.You can actually play with the headspace on a savage in very small amounts which can have some interesting power and accuracy effects. Id like to hear how they act around no-go/ go gauges and measure a chamber cast also. Chamber cast is cheap and would be best really. Stuffs all over the web. I just cant see a lapua being that far behind an edge. The 2850 load is pretty standard for a 30" tube. How long are the savage tubes? Its not horrible overbore anyway that it needs the extra length too badly. Heck most 338 ultras with 26 inch tubes are generally reported as being 2700-2750 fps guns when pushed.

    Be cool to look at. Another interesting thought is this:
    You can get a quick idea with scotch tape on the back of the case. If a factory shell will close with no resistance with the tape the chamber may be over. Conversely if the bolt wont close at all it may be an indication its under size. I wouldnt start grinding on anything without real measurements but it would be neat to see what it does.

    Not totally scientific but Ive screwed together a few that way.
