I played with BLC2, CFE 223, and H380. This was the best group out of all of them. Pretty sure the flyer was from a round that for some reason ended up with .007" shorter than the others. Going to go measure some bullets to see if that may be the issue. Otherwise, I'm pretty happy with this.
This is a 5 shot group of the Nosler book max load for a 55gr bt with CFE 223. Doing about 3320 out of a 20" stainless Proof Research barrel. Makes a pretty big impact on coyote.
If the BC on the 70 gr RDF holds up, it is out shooting the faster 55 gr. Bt by 400 yards. And from zero to 400 it is never more than .75" off from the 55gr. Bt. Hope to get some more of the 70 gr RDF loaded up and test them out to 700 yards.
