Thread: Ultimate compact rifle & catrige - 6mmGT/22GT in howa mini action

You need to get to grips with how bolt thrust works, there is a reason the mini action is smaller than a std 1500 ,. . . I also think the 6 GT would be a great cartridge for NZ, I currently run a 6.8 SPC (pretty much the same as the 6.5 Grendal) and something with a bit more snot but without the barrel burning habits of the 243 and 6 CM would be nice. I doubt you'll fine a gunsmith brave enough to do it in any of the mini actions, and if you do you'll find yourself in mag feeding hell, there is a big difference between the x39 based cartridges and the ex 308 ones.
