Re: Here's a question about the 338 caliber
.338 RUM- most economical big .338 to shoot, and does hand in with the edge and Lapua. I have one, but am not profficient to even 800 yards yet with it, 400 yards shy of hunting potential.good in a sporter wieght rifle. 2700-2800fps.
.338 EDGE- If your going econonmy custom, the way to go. out does the .338 RUM by about 100fps depending on if its a fast or slow barrel. it also has good barrel life and brass is on the cheap side. good in a sporter wieght as well.
.338 Lapua- performs somewhat similar to the edge on a shorter fater case. it is easier to have a slightly longer COAL. with the fatter case comes the issue of only the beefy actions can handle it (IMO). Brass is extremly good but pricey. 2750-2850
.338 Lapua Imp.- you gain a fair amount on the Lapua like JE CUSTOM said. IMO if one were to build on a Lapua case I would go with the Imp. should get you around the 3000 Fps mark.
.338-.378 Wby- Fat, Long and can only be handled by the beffiest factory action and good customs. the Wby Mark 5 is the action of choice for this one. decent brass but pricey and a long COAL but your in with th big boys now. 3100 fps with the 300SMK.
.338 Allen Mag.- The heavywieght .338. based off the .408 Chey-Tac and is Kirby Allens monster. It will be about the fastest thing in .338 and will drive a 300 SMK @ 3400 fps. Hard on barrels but a true 1.5KM+ cartrige. BIG CUSTOM ACTION ONLY. pricey but sweet... i want one.
There are a few in between, but those are the main ones. Kahn, Excalier, .338-416 Rigby Imp. are in there if you wanna look them up. I'm sure that LTLR will come chip in, listen to him when it comes to .338's.
