You know I tried 150gr BT and IMR4350. Accuracy was good, but velocity was only like 3300-3350. I was a little disappointed on the velocity.

Could you possibly use some H-4350 on 150 grains? I know you can't directly replace one for the other, but would there be a possible load there? I only ask because I had some left over from another cartidge I was test loading.

3350fps with 180gr bullets is quite fast with a 300ultramag.3350fps with 150gr bullets is quite slow for a 300ultramag.

Seriously If I could get 3350fps with 150's and still maintain sub moa I would switch right now!! I just dont think it could happen. It seems like every powder I use to achieve great groups, kills me on velocity! Im not argueing with you stubble, Im just explaining MY situation.

It sounds like either you just haven't hit the right load combination or there is a problem with your rifle.

Nothin to wrong with it I suppose. I don't mind being on the low side velocity. I do remember getting a cluster of groups that were one hole then a flyer 1.5" away. Happened a few times. i got to look at my target again. I only gave it one shot.

Stubble should we be getting 3500+ with a 150 grain pill? Do you have any suggestions on getting the 150's to shoot? Which powder?

I don't suggest IMR4350 to get 3500. At least it didn't work for me. I bet RL22 might be the ticket.

I have only tries 165gr and 180gr bullets and r-25,h-1000 and imr7828 all provided good results with r-25 being the best in my rifles.In my opinion either imr4350 or h4350 would be too fast for such a large case.
