I am thinking of a new build on a short action and am wondering if anyone has experience with the 6mm super long range? It sounds like a great round for target/varmint with the ability to push heavy 115gr bullets at reasonable fps (3000) without being loaded to the max! Seems to me, barrel life would also be good and the brass is easily formed by lengthening the neck by changing shoulder to 30 degrees on .243 win cases.

Just a thought
