Sorry if these questions are elementry, but I need some direction. First I have a Remington 700 ADL 30-06, I think a 1 in 10 twist, what is the optimum grain bullet? Second I have an Olympic Arms AR15 .223, I think a 1 in 9 twist, again what is the optimum grain bullet? I like accurate powders and use a LEE press and reloading book. I will be mainly target shooting with both at 50 to 300 yards and occasionaly hunting deer with the 700. Any direction would be helpful I'm just looking for good accuracy but want to stretch the range out if the zombies come knocking! Have to be able to put them down! Thanks guys
