Finally got a load worked up in my 22" 1 in 8" twist BHW barrel. This is an average 3 shot group at 100 yards with 23.8gr of 8208 behind the Hornady 73gr ELD bullets using CCI450's and LC cases. 5 shot groups look about the same and my 7" target at 700 yards doesn't stand a chance when the wind is low.

My chrono took a dump the other day but both the elevation and wind adjustments needed at 400, 500 and now 700 yards indicate I'm right at 2850 fps which is right where I estimated. No pressure signs at all. Its an honest sub 1/2 moa load so far, that particular group in the picture measured .37" outside to outside. Cold bore and shooter. To say I was pleased is an understatement.

Walked back and shot 3 more 5 shot groups. All 20 come in just under MOA. My muzzle velocity appeared to be 2875ish today. But it's 40 degrees warmer than last time I calculated it against bullet drop so that's not surprising.
