grain slug from a .30-30 but that was the best they had then.......we have some mighty fine bullets available to us today in bonding technology and the .30-06 is a clear step up from a .30-30.....I just prefer to use the best I can get as a handloader and to me.....for moose...that's a premium 200 grain bullet.
I guess what I am getting at is most moose hunting I have seen is some good long range shots. I would rather have the flattness of a 180gr or even 165gr premium than the extra penetration of the 200gr when it comes to a 30-06.
For my 300RUM, I won't mind a 200gr projection.
