working up a ladder load for .223 Rem (Gas Guns)
My .223 is the infamous Ruger Mini Ranch. "The best shotgun Ruger ever made"! So, I'm getting ready to start up ladder loads for the specific purpose of tying to improve accuracy. (Please don't comment on that). I know I can do better with a reload the gun loves and it is my duty to find it. Knowing fully well that when I get done, it may still give me 3" pattern at 100 yards.
My question is this, because the .223 is so much smaller (24-25 gr of powder) vs. say an '06 (57-59 gr), should I make my steps smaller? Usually I go with .3 gr steps from starting load to max (or near it).
Would I be smart to drop that to .1 or .2? What loading advice can you share.
Also, state regs require at least a 60 gr bullet for deer and antelope so I'll be trying 62, 65, and 70 gr bullets. It occurs to me that a 70 gr bullet could easily compress a load a 1/4" or more!
