Home Forums Reloading Big Game Rifles Bitterroot Bullets

Hello Everybody,
I have been lurking on these forums for quite some time, but this is my first post. I was hoping to get some information on some bullets that I recently happened upon, as an internet search turned up little. They are from the Bitterroot Bullet Company. There are 8 bags of .338 225 grainers, 5 bags of .358 250 grainers, and a lone bag of .358 225 grainers. The 358's have a home in my 35 Whelen (lighting up jackrabbits behind my house), but I do not own any sort of 338, so if anybody has a recommendation on what cartridge they might work good in, please chime in! The .358's have a printed minimum velocity of 2800 fps, but the 338's have nothing listed. Thanks!
