Growing up all we had were a couple 243s. Dads hammered hundreds of deer with a Remington 788 with what ever box of 100 grain ammo was cheapest at wal mart. I'm not sure on the twist rate of that rifle though. I've had 3 others that were 1-10, confirmed. Favorite bullets are 85 and 100 grain game kings. Also shot 100 grain pro hunters, I bought a bunch in college because game kings went up and I didn't want to fork out the extra money since I had none! The 85 grain gamekings seem to kill like lightning on small deer and will turn a coyote inside out. Never shot a big buck or mule deer with one though. Dad's killed some dandies with my 100 grain game king load I made for his rifle, never recovered a bullet.
