Don't you know that the old outdated 30-06 wont shoot like that? The cartridge is obsolete,a real waste of powder and bullets. It cant kill a big buck or a hog like a .30000000 winulapshmag.
Congrats. Its fun watching and listening to the know it all at the range talking smack and shooting their custom $3K+ sticks and then lay down a couple of one holers with the lowly 30-06 Savage :)
If you want to shoot something a little heavier, You might give the 165 Sierra Game King HPBT a try with a max load of that IMR4350. It's magic in mine :)
