I'll problly get some head butting here, but the 25/06* 270*280*30/06*8mm/06*338-06*35 whelen are all but close to being the same . The diffrence i see is in bullet selection. The 30 Gov. that started it all is popular because of cheap, and plenty of on the shelf ammo. The 270 was praised as the riflesmans rifle, with Jack leading the way. The others have had to more or less make it on there own. Like i've said before (apples to apples) it boils down to what you grew up with, or just a personal prefrence. Yes sir: i want one of each, but.......Do i want a 280, darn right i do, always have. At times have shot or hunted with each. My big boy toy at the moment is the 338/06 and i have not got board with it yet, its done everything i've asked it to do! (To make a short yes or no longer)
I group all these rounds together, with minor diffrences, you want a 280, than by all means get one, this group won't let you down at most hunting ranges, with the right bullet, and shot placement. With shot placement, there won't be any meat damage at any range. I've never shot a deer at 1/2 a mile with a 30/30, with open sights like some have more or less done...
You want it, get it, You don't like it, trade it, till you have your favorite, and it just might end up in this group of chamberings.
