I did not know about that acceptable powder range. Thanks for posting it!2230 falls within the acceptable burn rate range for the M-14.
Why not give it a try and let us know how it goes?
Between 3031 and 4064 is the generally accepted range for this rifle and on the burn rate chart I looked at 2230 is closer to 3031 than 4064 so it's on the fast side of acceptable.
Probably a good thing for the bullet you are using.
Either way, good luck.
