i've been playing with the idea of getting a custom ultra long range (1500m) tactical type rifle built. the first cartridge that came to mind was the 338 lapua magnum. thing is brass isn't exactly easy to get and it's damn expensive too. the 338 ultra mag basically does the same thing but for less money. the 338 would give me about 3000fps with 250gr and 2800fps with 300gr bullets. the 300 ultra mag would give about 3000fps with 200gr bullets. i know sierra makes 200, 220 and 240gr bullets for the .308 and they make a 300gr matchking for the .338.

what do u think is better for long range shooting? the 300 or the 338?

cheers
