For another comparison

A 22 creedmoor at max loads will shoot an 88 eld m at 3300fps
A fast twist 270 will shoot a 170 Berger (the highest bc projectile available at 2900fps.

For the projectiles to maintain the 1800fps approximate required for proper expansion the 270 runs out of steam at around 760m whilst the 22 creed runs out at 860m. The 22 creedmoor also wins in wind and does so with around half the recoil.

In factory ammo the most suitable longer range load for the 270 is the factory 145 eld at 2970

Or the 6.5 PRC equivalent a 143 at 2960
The PRC maintains 1800fps until 750m whilst the 270 only holds it until 670m. With reloading this gap widens with a PRC being able to reach closer to 900-1000m.

Yes factory ammo is slower but that's primarily a factory ammo issue and applies to both the 270 and 6.5prc.

I use the extreme end because any difference in close is way more than needed anyway so isn't really relevant. It's all trivial anyway as almost every calibre with the appropriate projectile is capable inside 300m

That extreme distance,,,
Yet Id guess that 98% of animals are shot under 500 m. if so we are really talking about a 2% difference which is negligible.

Id suggest only those who dont use a 270 would have rainbow ticks on their mind.

I'd suggest you have it all arse backwards

Fixed that for you

Are you saying you own a 270?

Arguing about ballistics and calibers on the internet

It's the old saying, it's not the size that matters it's how you use it that counts

Mines just a safe queen (king?) that gets bought out for special occasions
