thats great, thanks, how fast do the .257 burn out the barrel? I know a lot of that depends on the shooter

Top accuracy i would guess less than 1500 rounds depending on how you shoot it, as a Big Game rifle you will probably never wear out the barrel.

Do a Google search for (1) the .257 STW and read the article by Russell Thornberry - and some other interesting hits and then (2) do a Google search for the .257 Tamale and it will take you to the web-site of Jim Ferguson who builts quite a few rifles for those who like to go "fast".

In addition to needing at least a 28" bbl the problem with these speedster's is shooter's fall in love showing off the velocity to their buddies they're lucky to get a season or two out of the original barrel.

Here is my 257 STW . I barreled and chambered it myself . Shilen SS Match #4 barrel 27 inch. Left Hand 700 Action. Rel 25 and the Barnes 100 gr TSX . Elk was 510 yards Lasered . He just dropped in his tracks.

There is some load data on here.
