Re: Best .223 load for a 20 inch bbl
23.8gr of I-4064 gave .4's in my factory barreled Savage this weekend with the 75 Amax. First time shooting them, no chrony data, but it should be around 2800fps from the listed data.
Amax seem to like a jump around 10 thou from all the calibers I've shot them from, this was no different.
