Got this turned and getting mocked up for paint ...Itza 6mm W/-221/ WTF .... 300 necked down to 6mm. Quickload has the light 6mm bullets going surprisingly fast out of a 12 incher. Recoil shouldnt exist to any worrisome degree.
Trying to arrive at something my much better half could use without flinching.
Not suspecting it to be too different from KAC's 6 x 35 chambering.
