It has been mentioned that the .280 is more expensive but by how much? $6 a box I've found online for Hornady...that's a huge 30 cent difference per shell...How much shooting do you think you'll do with a hunting rifle after sighting in?
You have to weigh the cost of ammo to quality of performance...will $6 make it another 100 yards of lethality, X" less of drop in trajectory, greater accuracy or lessened recoil...For any one of the items I’d say yes, for all of them “I’d be shouting from the rooftops”.
If you reload when do you reach break even--that's when the cost of the equipment is nil? How many rounds do you have to reload before the couple hundred dollars you spent on a press, scale, dies and powder measure have been paid for?
Sure, you’ll find .30/06 and .270 in any Ma & Pa grocery/hardware in small town USA but don’t count on it anywhere else in the world as .30/06 and the family are the American calibre for after both wars there was lots of ammo and bolt action guns available for cheap...In Canada and other Commonwealth countries it was the .303 British, in Europe it was the 8mm Mauser, 7.5 Mauser, 6.5x55 Swede, 7.62x54R so favourites were based on availability and why my first rifle was a sporter SMLE...
Granted, availability at the local Wally World is important but I can assure you that I’ll be packing and rechecking my packing many times before going on a hunt of a lifetime so forgetting my ammo is the least of my worries—having bags lost/stolen by the airlines is another matter all together and if there is a Wally World there will probably be a gun store in the area as well and as long as you don’t have something really obscure, you’ll probably be able to replace it…
