Does anyone have any experience using H 450 behind 200 gr. bullet in their 300 Win Mag?

Thought about using IMR 4350 but the H 450 measures _so_ nice.

Thanks,

Don't know if this is any help. I have not used H450 in the 300 Win behind the 200, but I shot a lot of 180's with it. I used 76.0 grains behind the 180 Partition with excellent results. I would drop back at least 5 grains for the 200 and work up carefully. Regards, Eagleye.

Glad to hear you are getting good results w/H 450. I've had excellent results with it in the '06 behind 190 gr. match kings but never tried it in the 300 Win Mag.

Have been using 4350/150 nos. partitions in the 300 but not overjoyed with accuracy. Seems most like the heavier bullets in the 300 so thought I'd give them a try.

Thanks for your feedback.
