6.5 Creedmoor +Peak vs .30-06: The One-Gun Rifle Bet You Don't Have to Make
The .30-06 has been the one-gun answer for a century. I ran Federal's 80,000-psi 6.5 Creedmoor +Peak against it without looking at a single number first — and the result changed which rifle I'm buying this fall, though not for the reason I expected.

Maximum Point-Blank Range, Explained — Your Vital Zone Matters More Than Your Cartridge
Maximum point-blank range is the longest distance you can hold dead-on and still hit the vitals. We ran all 64 .270 Winchester factory loads through our ballistics calculator: the entire field spans 62 yards, while changing the vital-zone assumption on a single load swings it 109. The number you invent moves the answer more than the ammunition you buy.

Altitude and Temperature Don't Move Your Zero — Unless You Zeroed Far Out
Everyone says to re-zero when you get to the mountains. We ran a 6.5 Creedmoor from sea level to 10,000 feet and from 0°F to 100°F, and a 100-yard zero never moved — 0.04 inch across the entire envelope. What moves is everything past it: 33 inches at 1,000 yards. Unless your zero itself is distant, in which case all of this inverts.
