I am not familar with the 25-45, sorry.
It's basically just 25-223.I am not familar with the 25-45, sorry.
Those numbers are impressive. What barrel length?Look into the 25-223 it performs well brass is cheap, primers are available and would push those 70s to 3200+. I'm currently shooting 87gr Speer tnts at 2950ish.
My rifle has a 24" lilja on it with a long throat. I was really into it about 10 years ago and shot 75s alot at 3150fps, 85s at 3050, 100s at 2750, and 110gr at 2700. I slowed it down to 2950 with the 87gr tnt now. I have used most h335 and the canister equivalent WC844. AA2200 gave the 6-223AI I had some insane velocities but would go from looks fine to no primer in about .3grThose numbers are impressive. What barrel length?
My 24" .223 pushes a 69SMK @ 3033fps.
My 22" 22GT pushes a 77TMK @ 3200, or a 90SMK @ 3086, but big difference in case size between .223 and 22GT.

Goal is 133s or 135s near 3200fps.
It should scream a 70gr out about...3600-3700?
