I bought a Rem 700 BDL in 270 in the late 60s (68) I think. Never an issue with it, killed two grizzlies, a lot of black bears, elk and deer with it. A bunch of prairie dogs too. Has always shot nickel sized groups at 100 yards with 150g Partitions cooking along at 3000 fps. My son has it now and killed his first elk with it. That being said, quality control sucks now at Remington. I bought a new XCR II in 375 H&H in the spring of 2011 for my brown bear hunt. It wouldn't chamber Remington factory ammo, the extractor was too big. So I had a Sako extractor installed, the bolt handle welded on and had it rechambered to 375 Weatherby for good measure. Now that it's been "customized" I do have to say I really like the gun. It weighs 7 1/2 lbs with a Leupold 2-7x scope on it, is as weatherproof as your going to get, shoots .5 MOA and the stock seems to soak up recoil. A 300g A-Frame at 2700 fps will kill anything on this hemisphere without a problem.

So if the 458 Rem Custom is an older one, so much the better. Probably needs no work at all.

Merry Christmas
