In the early stages of developing a load for my Ultra Lightweigh Mark V 257WBY. I am gonna try the 115gr Barnes TSX bullet. I was looking at Barnes data and they show a max load of 67.5 gr. H-1000 at 3.17". The hodgon website shows the 115 Barnes TSX max load at 71.0 gr of H-1000 at 3.25". My questions is 0.08" enough to stuff 3.5 grains more powder in the case? Is Barnes saying seat the bullet deeper for more jump?
