Dave,

6mmGT was designed for the PRS guys in the USA. Is between the Dasher and 6x47Lap in case size. Its made to provide reliable mag feeding without modifying AI pattern mags that many use in PRS.

Its not as efficient as the BRA, Dasher, etc from what I've seen. Runs same speeds as Dasher using more powder.

If I'm gonna build a Heavy Gun, Id look at a 7mm08AI. I used to run one for F-Open before SAUMs were what was needed to do well. 160gr class bullets at 2820 range and is quite accurate. Got the high BC of the 7mm bullet with the recoil of a 308 or less.
