[QUOTE="Robtattoo, post: 5319852, member: 11961"] I'm about at my wit's end with this damn Kimber. I was really wanting to shoot 100gn bullets, but it looks like that isn't in the cards. I've tried Partitions, Core-lokt & SGKs. I know there are others, but these 3 were what I wanted to work up for (pigs & bigger, range time & whitetail) I've tried so many combinations around the 'magic' load with IMR4350 is not even funny. Nothing from 43 to 47gn will shoot under 3" whatsoever. I've dropped below book minimum to way above & nothing seems to do better than 3". I thought I'd found a happier spot at 46, but my last range trip slapped them all into 3" again. I'm not seeing any group shift, all group centers are consistent (it's not the scope or mounts) it just doesn't seem to want to shoot 100 grainers. Doing a bunch of online snooping, it turns out that this seems to be common, even with the 1:10 twist. They seem to like <90gn and >110gn. The mid weights don't get any love. So. Has anyone had any success at all with 100gn bullets in the Bob? If not, what's the consensus on 80gn TTSX on accuracy & game? I've read a ton of very positive accuracy reports on the Barnes/4350 combo, but no dead stuff reports [/QUOTE]
