  At the last match I attended I had various conversations with a bunch of people about a new project I was into. Most of those in the conversations were interested to the point of asking me to keep them updated with results.
The 6mm Grendel Imp is a 6.5 gGrendel necked down to 6mm with shoulder moved forward and squared to 40 degrees. A relatively short  .2 " neck is left. PPC bolt face required.
 I'm about half way through load development and am very pleased with the results so far.

I'm shooting 103 grn copperheads (mollied) & am having absolutely no problems running them up to 2970 fps with a case full of 2206H. Accuracy, at this point, appears to be best at about 2930-2950 which with this bullet will get the job done at long range. I have a 26" Rem Varmint profile barrel screwed onto my PPC  weighing under 11.5 lbs.
I intend to keep playing with seating depths & other powders but I'm sure this will be a competitive cartridge at 500 meters.

Full length neck bushing die and also a hydro forming die were supplied by the gunsmith. This particular hydro die will neck the case down from 6.5 to 6mm at the time the case is formed.

I guess this post is mainly  directed at those short range shooters who might be interested in the 500 Fly. You guys already have the platform in your PPC's. This the low cost solution to long range shooting. Simply get another barrel chambered and you're good to go at 500.

I will update results as I continue to develop .
