I am starting this thread to hopefully pull some up to date info on the .338 snipetac since many posts and threads are years old. I think with current and soon to be on the market bullets this cartridge will become more popular. My build: 338 snipetac Built by Dallas at Lane Precision Built on a BAT c.t. slightly customized to help with idaho hunting weight limits. -32" rock creek barrel with a terminator t4 brake. -McMillan at with carbon shell. -Evolution bi pod and mount. -Nightforce nxs with titanium 6 screw rings. Firing bertram factory brass Berger 300 grain otm's Federal 215m So far h50bmg, will be trying the 20n29, not excited but may try the 869. Any suggestions on powder? So far this rifle has about 20 rounds through it all on virgin brass. We have ran up to 3180 fps with 138 grains of the h50bmg. Will start running formed brass and see the difference also the barrel will speed up so wondering what velocity this may show. We are really anticipating the berger 330 or 329 grain that has been talked about as well as the possible 325 grain smk.
