I have Remington 798's in .300 Win. mag. and .458 Win. mag. Also a Remington 799 in 7.62x39. Awesome rifles for the money I think.

I broke the extractor recently firing steel case ammo in my 799, some rounds fit tight in my rifle, no issues with brass cases. I couldn't locate an extractor anywhere for it. A knowledgeable parts supplier suggested that an extractor from a Sako Vixen rifle would fit. Sure enough, it did. Got a spare just in case.
