lapua .310 200g fmjbt in a .303?

In my search to find .311 174 SMK's I ran across these on hirsch precisions site, was wondering anyones tried them in a .303

Nope. Too small for most Lee-Enfield barrels. Mind you, a .311" bullet might be as well.

Thats the problem with .303's some its too small some its just right and in the occasional one it might even be too big

Slug your bore and find out. Only easy way to tell.
Both my current 303's (P14 and Martini-Enfield) will shoot .308" bullets all day but the accuracy isn't great. I used to have a Lee Enfield with a ~.316" bore that would tumble anything under .311" (including .3105") and still shot like crap with .312" bullets. My current 303's shoot quite well with .312" jacketed but I haven't tried .310" in either one. My guess would be that unless you have an exceptionally tight bore those match .310" bullets will be largely a waste.
