Anyone seen the article in Shooting Times this week? Why invent a 'new' 6.5 mm? A lot of work for nothing that a 6.5x55 can't do. Steep shoulder on the round equates to high throat/lead wear if you bang big loads down it. Thoughts?
I think you have to consider that the load was developed for a short barreled (18") rifle. When you actually look at the ballistics for the round I doubt whether any of the standard 6.5s could produce such results this round did. That said its an awful lot of work to produce the case let alone work up the loads. You can do pretty much the same thing with a .308 and lightish bullets.
I am certainly no ballistics expert but if Joseph Whitworth hadn't taken the 1853 pattern Enfiled in hand to produce the Whitworth rifle, today we might stilll be talking about grouping 3 shots somewhere on the side of Fallow Buck at 100 yards and think that was ok! I bet some people laughed at him for trying something new as well.
Of course, there was also Gorbly. He invented a new wheel. In many ways Gorbly's wheel was excellent. unfortunately however, his wheel was triangular!
