Lapua!!
A hit straight to the head of the nail
“ The .270 is a good " Old Timers" caliber.
Technology has surpassed it. Still kills. Mediocre at best in today's world 🌎”
But mediocre?!? Give me at least tolerable, acceptable, manageable some kind of word ending in able and miserable is not an acceptable option 😃
I agree technological improvements have helped all calibres and cartridges substantially “a high tide lifts all boats”
A serious question, coming from my complete ignorance of the cartridge, what is it about the 6mm CM that makes you so enthusiastic? How much of an uplift is there over the .243? Does the uplift show in ranges of 450 yards and less?
One of the drivers for the question is my daughter’s go to rifle is a Vanguard Camilla in .243, the number of rounds she puts down range practicing over the summers makes the likelihood of a new barrel in the next few years possible. Wondering if 6mm CM vs .243 would make sense when the time comes.
Thanks in advance for your thoughts.
George,
The main advantages of the 6 CM over the .243 are:
- shorter case length, so you can fit long, sleek bullets in a SA magazine
- abundance of quality brass and factory ammo
- factory twist rates are suitable for the sleek bullets available today
- less case trimming due to the steeper shoulder angle
- theoretically longer barrel life and fewer pressure excursions due to the steep shoulder and long neck, as well as slightly less case capacity
If rebarreling a hunting rifle, some of those factors are irrelevant, so you’ll have to decide if it’s worth it to you to switch.
