This is my first time on here other than as a guest and I like it!I have a quick question i'm looking at these three guns and don't know which to get.i already have a 270 win.this gun will be used for all the bears and possibly water buffalo.each caliber has an advantage,the 300 wsm 'cause i see as many of them as i see 223.the 300 win mag comes factory loaded with 240 gr.woodleighs.and the 45-70 because it's as old as dirt and its proven.which would you get?
