Well, with the ammo shortage going on, I can't find any 225 Hornady HPBT any more, so I had to get some 230 Berger Target Hybrids. My question is, should I start from scratch with the 230's, or just put a few 230's on my 225's load, & see where it leads me? They are 5 gr heavier, but have a shorter bearing surface, so I think they should be a lower pressure with similar, to higher velocity over the 225's load.
