It is probably more effective than a .300 Win mag at extended ranges by giving you comparable energy at perhaps a hundred yards further out. Hardly worth the ammo cost, barrel life, recoil and blast. If you have never fired one with a full house load, you might consider another caliber or you can buy the Power Level I or II ammo from Remington comparable to a .30-06 and .300 WM respectively. Gee, I wonder why they did that? Go figure. I suppose if I won it in a raffle, I would try it or trade it.

I would agree with WA Mtnhunter and steve182, trade the thing for a .300 Win or .300 Weatherby...

I own two 300 RUM both custom made by prominent rifle makers. Used them both on two 30 day safaris, so they both were used extensively. Neither of them shoot as accurately as any of my 300 Win Mags. I use heavy recoil rifles all the time, so "kick" alone does not make them less accurate. They are both more tempermental to handload than the 300 Win's. My purpose in having them made was the larger case capacity should make them more suitable for a two hundred grain bullet, which I used to prefer in Africa. Because I had discovered the 200 grain ruined less meat than the 180's and worked fine if one got in a situation with large cranky animals. New ammo products have negated this advantage. I have gone back to the 300 Win Mags for my light rifle using the 180's.

In summary too much recoil, not enough accuracy, ammo too expensive, barrel to long, etc, etc.

Have two Ultra Mag in my closet I would part with to a more sophisticated hunter and rifleman than I.

The only thing that I have had done to my A-bolt medallion is have the trigger polished to give a better pull. The recoil doesn't seem any worse than my 12 ga. shooting slugs it just a quicker feeling kick.

I forgot, mine don't have muzzle brakes because many African professional hunters won't let you use them.

Hey WAM tell us what you REALLY think! I agree BTW. When I used the 375 H&H in AK I fired 2 rounds one at the range to check Zero and one at the Moose.
