Just neck a 308 Win down to .277 and you call it a 27-08 and you have a good round. Also, a 25-08 would be cool and easy to reload if we ever get in a reloading pinch like we did 10 yrs ago. I was very low on brass back then but I could still go to the shooting range and find once fired .308 cases. The last thing we need is another caliber unless it can be reloaded from polar cases like the 30-06 , 308 ETC.

But the fruits of the spirit is love, joy, peace, patience, kindness, goodness,faithfulness, Gentleness and self control. Against such things there is no law. Galations 5: 22&23
