Home Forums Reloading Varmint Rifles Pet loads for the 243

H4831SC setting under 100gr SGK gives great accuracy and knocks the snot outa deer .
Shoots under .5” pretty consistent in 1/10 twist 700 and .75” in 1/8 .
Same powder under 107 SMK in 1/8 shoots bug hole in the teens .
105A-max , same powder , .5”
Didn’t get to far on load development for A-max , ran out of bullets .
Not factory barrel .
As said 70gr TNT is very accurate too , don’t recall powder right now , been using 222 and 17HMR for groundhogs.
