RE: smallest grain 30-06 ammo?
If i'm not mistaken Remington use to offer one in a factory load that was 55grns called the accelerator but it's been a while since i've seen them. I also saw them offered from Midway months ago but i can't recall how long ago it was but it was only the bullet itself and in bulk of about 500 per box. I just checked and can't find them anywhere on the web so i'm not sure if there's any around to be found or not. I don't know how accurate they would be but thats a pretty light bullet coming out of a 30.06. On the other hand if you handload then i guess anythings possible.
