I am going to have a cust rifle made some time soon. My goal with this rifle is to be able to take large game as small as deer and big as oryx and elk at 1k and under. My choices that I have decided on are the 300 win mag, 300 RUM and 338 LM (just because I can?). I have asked a couple of knowledgable guys on here about this but thought it would be interesting to put it as a poll. Which would you choose and why?
I love the way the 300 grain bullet puts stuff down. I have a couple 300 rums & really like them and practice with them but have never taken them to my longrange stand because I have so much faith in the 338. I have also shot the 300 win mag to distance and in my opinion its not in the same league for making first round hits with any wind at longrange. Im an edge fan,but of your choices id go with the 338.
My response is assuming your willing to build it with no restrictions. Such as limitations of no brake, or only a 26 inch tube, under 9 lb etc. if you do have limitations like that my answer may be different. Good luck
The 338 edge definitely has the advantage over the other two cartridges with power and wind! The 300. RUM also puts the win mag in the dust. I am in the beginning of starting a build for long range hunting purposes. I am choosing the 300. win mag! still has plenty of power and speed to harvest big game out to extended ranges plus you dont need a brake! You dont need to fire form (338 edge), cheapest in reloading, and has the best barrel life. Another plus side is if anything ever went wrong where you ran out of bullets, or lost/forgot some you can run to the closest store and pick up a box of 300 win mags. Cant do that with the edge and harder to find the RUM.
If i had the money, and experience and capabilities i would LOVE to own and shoot an edge due to the power! But for me, the 300. win mag is more practical.
I voted for the 338 because you stated you wanted a 1000 an elk. The 300 has plenty of power to do it and I think if you were just talking about energy and possibly a little easier to shoot I would vote that but I have been hearing that the 338 gives much longer barrel life. I was having the difficulty of deciding between the 7 RM and 300 ultra for my build. I went for the 7 to learn with. If I find I want to shoot further on elk than 800 I will jump the 300 most likely and go to the 338 simply for brrel life and the gain in power is much more. Using the 300 vs the 7 you only get a few hundred foot lbs more but have a large increase in powder, recoil, bullet weight, muzzle break... if Im going that big I think I would just take a full step and get the 338 and get 600+ ft lbs of energy, over what the 7 mag can get with 180's. I hope by the time I rebarrel berger will have a 338 bullets out in the 250gr class hopefully around .7 bc

My vote goes for the 338. It seems to be much more consistent and predictable in the wind than the 30 cal and the smackdown it delivers on animals is just plain awesome. The downside is that it is not as easy to handle in a lightweight hunting rifle. 12lb rifle and a muzzle brake make it a pleasure to shoot. My current long range rifle is the 338 edge so I may be a little biased.
