fastest 338 caliber?Build advice?

What is the fastest 338 caliber? The fastest I know of is the 338 allan mag then the 338edge and Laupa are very similar? I do have a 300 ultra mag so the edge is tempting. Are the prefit and chambered barrels hard to install on a remington action?
I will tell you guys what I am looking for in a gun and for what uses If you have ANY advice feel free to share. I live in Colorado so I can shoot long distance all day, if I have the right gun. In adition to hunting Colorado every year I put in to draw trophy tags in almost every western state? My dad and I have shoot many elk and deer out ot 600 yards so I am not a total rookie.
1.I want a gun that hits veryy hard way out there? 2.That way I can spot my misses and hits better? 3.The biger bullet should also help with marginal hits on big game(no one is perfect)4.I want a big eficent bulet so the wind does not effect it as much. 5. Also the big bullet should drop game more than typicall 300ultra mag 168-190g bullets. That way when I am walking all the way over to my dead trophy I know it is dead instead of thinking I hit it and hopefully taking up the blood trail whaere it enetered th trees? I am thinking 300grain SMK will help me fullfil the above wishes. But again I am open to suggestions. Do the 300SMK fit in a stock magazine or do you need a aftermarket magazine?
If I build or buy one of the above calibers to shoot a 300SMK in a 1 in 10 twist barrel and then berger comes out with a higher BC bullet or hensen gets good reviews, will I need a new barrel to handle a longer bullet? Or are the 338 caliber barrels less picky than the 284 and 30
caliber barrels?
What are you allan mag guy's paying for brass and custom dies? Will MR. Allan or Shawn Carlock send you a prefit barrel chambered for 338AM with a muzzle break or do you have to buy the whaole gun?
Do the 338calibers offer the best speed to weight to BC ratio or should I look up to the 375 calibers? I don't have enogh money to buy a gun and then find out I would of been better of with something else. Or buy a gun that is good to 900 yards but my ability is more than that.

Sorry for rattling on your eyes should return to normal in a couple of hours! Thanks for your advice, Gabe

P.S. If you have a caliber you would recomend tell me why you like it and if you would of had it built a little different and why? (you new in your gut that a post this long was going to have a ps)

Re: fastest 338 caliber?Build advice?

You have 2 options, both of which are great. You can go with an entirely new rifle and keep the 300RUM as a backup/carry rifle (my choice). Or have your rifle rebarrelled. If you have it rebarreled, the 338 Edge is the choice. It will easily get you to 1000yds as long as the wind isn't horrible, it will hit with plenty of authority as well (2700+ ft lbs with the 300SMK at 1000yds).

If you can see your way clear for a new rifle, then go all out and have Kirby build you a 16lb 338 Allen Mag. This cartridge won't fit on a normal action, so you can't really upgrade your current rifle to the 338AM. But you will have a real hammer. With less than 5mph wind, it is absolutely no challenge to hit first shot at 1000yds with mine. It's very rewarding to hit at 1500+ too (targets only so far). At 1000yds, the 338AM/300SMK brings around 4000 ft lbs to the target!

Hope this helps, there are tons of pictures and discussion of the Edge and the AM's here on the forum.


ps: where are you at in Colo? I grew up on the western slope and will be out there elk hunting in October.
If some is good and more is better, then too much is just right.

My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives

The sky's the limit and so is the price if you want "the fastest". You could 338 Allen Mag, 338 Snipetac, or maybe some form of 338-50 BMG...barrel life would not be impressive, but the smack on steel would!

Re: fastest 338 caliber?Build advice?

I have been shooting the Lapua version or a variant for almost 20 years. In fact am loading some fot the Slowpoke this afternoon (RL25, 7828, WMR, 870, H1000) to develop my loads for a hunt in a couple of weeks in NM at the Mescalero Apache Reservation. Never had any anmial run more than a couple of hundred feet after getting hit with the 250SMK. One of the reasons I stick with a Lapua variant is because of the brass----second to none.
The Truth Is Not Always Good For Business!!
