I re-read (for the 900th time) this statement today and for some reason it got me thinking about it... I really don't have an answer for this one, and I'm tempted to do some calling around to see if I can find out...

Are there REALLY more 30-06 or .308win rifles being produced today than other cartridges?

Even if you exclude the dominance of MSR's in the market right now, I don't think I expect that 308win has a dominating sales volume in the market among other cartridges today. I'm not sure that any given cartridge enjoys that station any more.

I'm gonna be sitting in airports tomorrow, monday, and wednesday next week, believe I'll make a few calls to certain manufacturers to see if they're willing to share their relative production numbers for "top selling" cartridges.
