CFE BLK with the 200 FTX panned out better than expected. The range was too wet to walk out to 100 yards so these 5 shot groups are at 50 yds. 35.0, 35.5 & 36.0 are where SD started to stabilize in the teens. Magnum primers may help this but I horde them for big doses of RL 25 in my 7mm Mag. Best group was at 36.0 grains (COAL:2.560") with avg. of 2267fps. Brass looked good & recoil is a peach. The blue line on my dummy load is where the base of this bullet is seated. My velocity is right where I want it, so I'll just load some more at 36.0 to confirm these results at 100yds.…
COAL of 2.560” fits in my 18” SSK in Encore - CBTO of 2.040”
Have a ladder test (CFE BLK) waiting for a range day. My Speer 180 load (AA1680) is getting 2470 suppressed & grouping them inside of 1 3/4” at 100 yds. I agree, the real performance will come out of one-shot platforms.

I am hoping to work up a load w 140gr Barnes copper solids. Was thinking H110/W296. Has anyone tried either of those powders? Shooting a Henry.
I used the data from Hodgdon with a few substitutes with great result:
Here is what I loaded for my 360 Buckhammer on a TC Encore frame with a 22” MGM barrel.
-Hornady 200gr FTX COL. 2.55
(bullet not on the lands)
-CFE BLK 36.5grs
-WLR Primer
-2379 fps.
I shot from 50 yards. Groups consistently touched some same hole. this cartridge has great potential for single shot rifles.
