Personally, I would go w/the 200 gr Accubond. Retumbo or H1000 would be my first choices in powder. I wouldn't try anything lighter than 180 gr.

With the powder capacity of the RUM, the heavy bullets will be much more consistant. I tried the 125 NBT in a 300 RUM and now I don't shoot anything under 210 gr.

Against Bill's wills I to shoot 180g's :P I use 180g Barnes Triple Shocks (TSX, a pricey bullet keep in mind), 96.5g of Retumbo powder... I'm only keeping the bullet it small because I have a thought in my mind i'll rip a deer to shreds if I go bigger, but the 200+ grain bullets are always in my mind and I will probably end up switching anyways for the long range shots (500-1k) which I know will make him happier with me!

I really don't mean to preach to everyone on this issue. It's just that I've seen a 300 RUM shooting a 125 gr Nosler BT @ about 3960 fps require more windage to hit a pd @ 500 yds than my lowly little .243 shooting a 105 Amax @ 3100 fps.

BC AND speed together are what makes a great long range bullet. It's just that this relationship is about 80% bc and 20% speed!!

Yes, I've started to see it first hand as I start to shoot between the 500-1200 ranges... Still afraid to hit a deer with the bigger bullet though [img]/ubbthreads/images/graemlins/tongue.gif[/img]
