Sounds to me like I just found MY new pet load.60grs of H4831, CCI200 primer, and any 130gr bullet will give you sub MOA and around 3100fps. I load the Nosler Ballistic Tip for a friend and he gets 1.5" groups at 200yds with it. That is the Jack O'Conner load.
Never saw a use for them. That nosler bullet when started at 3100fps has a MPBR of 300yds. That O'Conner load has been killing deer and elk out west since the 270 came out. It is the load that MADE the 270 reputation. Work up to it and you should be happy. I have yet to see a 270 that wouldn't shoot that load under 1" and it drops deer like lightning.Sounds to me like I just found MY new pet load.
Dms, do you have any experience with the VLD's from Berger?
I love the 140AB. It cost a little more money than some like to spend but to me its an outstanding performer at the range. I launch the AB with IMR4831 at 2920 for targets and 2990 for any possible hunting. So far I,ve not hunted with it but as you say it has proving to be another tiny little cluster grouper for me too.Winchester cases, Winchester WLR primers, 140 grain Nosler AccuBonds and 58.0 grains of H4831 SC. They have been working great on elk and mule deer here in Utah and shoot "lights out" for accuracy. Good luck
