Hello

I have an axis 2 heavy barrel in 223rem I am thinking about doing 300yard matches with it and I know I will have to use something like 75gr A max but I'm a little concerned with the short throat of my rifle. 2.250 book data for a 55gr v max is too long and must be 2.230 to be 10k off the lands. Will I have any issue with the 68gr or 75gr bullets with this short throat?
