Prediction – 6.5 Creedmoor Cartridge will overshadow the .243 Winchester by Ed Hale |

I owned a .243 Winchester and tested a few Rifles in that Caliber for my New Hampshire Rifleman Magazine. I loved the accuracy and low recoil but it always nagged at me that bullet weight and CXP Criteria Limited the Cartridge to deer size game. Hornady’s HIT’s Calculator does the same. I entered 110 grains bullet, .243 diameter and velocity 2700 fps at impact and got a HIT value of 790 making it a medium game deer cartridge or smaller.

On the other hand with the 6.5 Creedmoor at 129 grains and Impact at 2700 fps it puts me into large game for 100 yard impact velocities with very similar low recoil. Further, that the sectional density SD of the .243 Winchester is .242 or less and does not have enough weight for its diameter to “reliably” penetrate sufficiently on larger game such as elk.

I tested rifles with 6.5 Creedmoor and found them easy to shoot and low recoil yet todays bullet advances make it ideal for both target and hunting with the 140 to 143 grain bullet on big game above deer. But I still consider it for thin skinned game like elk and big black bear and close-up, under 100 yards for big moose broadside only. Where it shines is long range! With an extremely low drag bullet it is fantastic for energy retention. I own a Ruger American Predator in 6.5 Creedmoor and simply love its accuracy and low recoil yet can take a broadside moose in the right hands with good shot placement. Accordingly, I sold my .243 Winchester.

In the case of the 6.5 Creedmoor the SD is .287 with a 140 grain bullet providing ample penetration for its weight vs diameter on CXP 3 size game and the 143 grain Hornady ELD-X nearly places it in the Winchester CXP-4 category.

The 6.5 Creedmoor was created for Target and beats the .308 round in long range competition but with Low Drag Ammo the 6.5 Creedmoor shines in Long Range Hunting for Big Game like Elk and African Plains Game like Kudu and game under the Eland.

Recommended Energies for Moose are 2500 ft-lbs but that hasn’t stopped the .270 and 30-06 hunters from using these rifle cartridges on Moose at over 100 yards and believe the 6.5 Creedmoor will kill moose cleanly at 100 yards or less with a well placed broadside shot.

There is one attribute that Jack O’Connor, a great hunting mentor, would be greatly pleased with, and that is low recoil, thus allowing for very accurate bullet placement. This he discussed this incessantly in regard to the .270 Winchester with 130 grain bullets.

In conclusion the .243 Winchester’s recoil as compared to the 6.5 Creedmoor is a little less but so is its limit on game hunted. Thus I predict over time the 6.5 Creedmoor which is supremely accurate and delivers CXP3 energy and high SD for deep penetration will overtake the .243 in future sales but will not erase the millions of rifles chambered in 243 Winchester for CXP2 or less size game.
