Finally found the load I was looking for for my .223 NEF Handi Rifle. Went to the range at lunch-time today and shot a 100 yard group that measured .650.
Load was:
CCI 400 Primer
Winchester brass
55gr Hornady SP
25.4gr IMR 4895
COL 2.200
Plan on trying a bit of deer hunting with it this fall (no flames please, I know my limits).
I have GREAT varmint load that will shoot 3/8 groups all day at 100 with a hornady 40gr V-MAX, but would never try that bullet on a deer.
I have tried a LOT of combinations of bullets and powder (mostly ball powder) with this.
H335
H322
Win 748
Speer 55gr
Sierra 55gr to 63 gr (might try the 63 gr again sometime with the IMR 4895)
Hornady 55gr to 60 gr
My conclusion is this, my gun likes the slower powder, AND never give up!
