300 WSW............. talk about over-kill!
I guess if you are dead set on a 308, you can use that 125gr. Speer TNT but the max' launch is barely 3000 fps out of a 26" barrel, the BC is only 0.326, with a 200 yd zero it will drop 7.6 inches at 300 yds but almost 2 FEET 22.7" @ 400 rds
would meloniting the barrel after breaking it in increase barrel life on those barrel burners?
Must admit I would go with something like .22-250, .243 or maybe a .25-'06, Would you think about a 7mm Rem Mag? Why the .30 requirement?
