| I finally pulled this baby out of the safe after waiting almost two years for the brass to be made. Initial test to check for function 2600 fps 5 shot avg with 75gr V-Max hopefully within the next two weeks i will have a range report and more load data. I will be trying 85gr Nosler Partitions for deer and keeping the 75gr V-Max's for coyotes which i built this round for initially. MGP |

LOL Quality Cartridge 500 pieces Notes are at the shop be if i remember correctly 31.8grs H2o Large Rifle Primer i really wanted small but if this round is accurate i will have some made so i can push it to higher levels. Im using PRI 6.8 mags so i can load OAL to 2.315" |

I'm curious about the cartridge. Ballistics seem rather weak though from what you're describing. I mean a 223 can easily push a 75 gr. bullet well past 2,600fps. Unless it was a typo and you meant 3,600fps, in which case, THAT would be the jizz. You can not hunt Deer in CT with a 223 ,Thats one of the reasons i did this round and another reason was just for the hell of it Dam it gets expensive when your bored  , plus you can not get a 107gr matchking for a 223 either. I can load any bullet for a 6mm and it will fit in the magazine.

Wildcatting gets in your blood, I know, I am not sure I could have waited two years to turn it from a expensive club, to a firestick. Were you not able to make brass from the 30 Rem? What is the twist rate, it will need to be a 8 twist to shoot the long bullets' and quicker than that to shoot the 115gr. BRD is bad enough, WildBRD is down right expensive, and mind-consuming. |

This barrel is set up to shoot 75-95gr bullets its a 1-10 twist. I could have made them from 6.8 or 30rem but then u would have to neck ream and i did not want to go that route.The brass was suppose to be done in 20 weeks but you know how that goes. |

7.62x39/grendel with a rebated rim ? No the case is the same dia. as the 6.8 but its blown out a bit near the shoulder area. 6.8 standard case taper from base to shoulder is .020". What smaller taper did you go with to increase capacity? .017" case taper from base to shoulder |
