Re: 284 Jazz
I don't know yet about the 200 wildcats but I can tell you some results myself and Nate learned this afternoon. First off it was a terrible day to do any shooting. When we planned it the forecast called for 58 and breezey. I guess breezey means 25-35mph guts from every direction it seemed. The wind was so bad while laying prone it would blow you off your target a couple of inches.
We used Bob C. 189's with US869 powder and fed match mag primers.
Eight of nine shots with 97.2grs of US869 had a velocity of 3205-3212. The ninth was 15fps less. ES of 7fps. With 98grs. Nate noticed a slight change in bolt lift with a velocity of 3267fps. I am sure you can push it over 3200, but I am not after the max performance. The group averaged .8moa throughout the testing(94-98grs), but it is tough to group in the conditions we had. When it gets nicer this evening hopefully I will get out and do some grouping with this load. Hopefully Nate will chime in and add since I am sure I missed quite a bit of important information.
Nate at SSG did custom dies and shell holder for this caliber, he also has brass on hand.
