GS makes a 170 grain .323 bullet that I have not loaded yet but intend to, i am told 3400 is reasonable, I will settle for 3300 fps. I have 180, 215, and 235 Blue Mountain bullets for it, 250 grain Hawks, 180 grain Nosler Ballistic Tips, 200 Grain A Frame, 220 Grain A Frame, and I believe Barnes makes a 200 and maybe another bullet it for it. Double Tap as well as Remington has factory ammo. I live in Alaska and have settled on the 8 Mag as my Alaskan Caliber. Yes it wont do any thing the various 300's or the 338 Win or 340 wea wont do but than again many calibers over lap. I shot my Dall Ram at 450 plus yards with a nosler ballistic tip I dont know that I could of done so with the 308 I was going to use. Also one gentleman in here had his 8mm rebarreled to a 300 Ultra Mag, I had a 300 Ultra Mag, Browning, A Bolt rebarreled to the 8 Mag. I love the cartridge but there are others.
