.17 hornet, CFE blackout powder. Big speed increase.

I gave this powder a go, on a few loads today, very big improvement in speed over ADI 2207, (H4198)
Shot in a Cz American std 22' barrel. 20gr v-max. fitted with DPT moderator.
Current loads.
ADI 2207- 11,7g, WSR, hornardy 3220fps
12g " " 3325fps (case is full to top)
N120 10.5 " " 3315fps
factory hornardy ammo 3540fps.
Trailboss 2g " " sub sonic, (25gr bullet)

CFE Blackout, Hornardy brass and WSR primer. five shots of each.
20gr v-max.
12g - 3470fps
12.3g - 3566fps
12.6g - 3738fps
12.8g - 3779fps, :omg:
Sd spread was between 20-35 on all loads,

25gr hornardy hollow point,
11.2g for 3187fps.

All grouping about 6-10mm at 50m, or same as all other loads, Just finished, repriming and resizing brass, and have settled on a load, of 12.5gr, hopefully find a few rabbits to test on this week. Impressive performance increase,:thumbsup:

Your first group of loads mirror what i have been able to acheive with powders available here, same ones you have used and a few others, was dissapointed with speeds although accuracy was ok factory loads, Hornady 20 grain, was getting 3660 fps and 10mm groups at 100 metres. Will try to get some cfe and try that. Thanks for the info.
