Ditto! There's a reason why the classics are the classics--cause they work.
New calibers are fun for gun nuts to play with and figure out but they only bring certain benefits because they were only designed for specific shooting issues. Take the latest whiz kid 6.5Creedmoor and compare it to the old 270. Ron Spomer did it in the linked article below. The Creedmoor was designed specifically for shooting at 1,000+ yards with a little less recoil so long range competition shooters can shoot even smaller groups. It's a phenomenal caliber and cartridge and stays supersonic out past 1,000 yards. It was designed for competition match shooting at long ranges like that.
Compare it to the 270 which was first released in 1925 and only got better as bullet technology improved. It was designed for hunting and excels at that. The 270 was never designed for long range competition shooting. Yet when you compare the 270 to the Creedmoor ballistically, it holds its' own out to 700 yards which is lots farther than 99+% of us will ever shoot at a big game animal. Most hunters will shoot at less than 250 yards, so that extra performance past 700 yards will never be needed or used in a hunting rifle. You'll pay top dollar for a Creedmoor or one of the other new whiz bang rifles and calibers. You can find used 270's generally with a Leupold or other good scope already on them for a deal all the time. Put some kind of recoil reducing butt pad on it if you're that recoil sensitive and you have the recoil equivalent of a Creedmoor for about a 1/3 of the price and a lot of money left over for hunting.
