choosing a caliber

[Al LaVodka]

I recommended elsewhere here, in a similar inquiry, as you are looking to reload, to get as much out of one of your .30-06's by having it reamed to .30-06 Ackley Improved -- you can get 100 fps more out of it and still use regular factory .30-06 if you want. No downside, just makes it a .308 Magnum!
