I have a Ruger 77 in 7mm Rem Mag with a barrel that is quite heavy. I have considered having it fluted or turned down but decided against it. I have one other 7mm Rem Mag, a 7mm Dakota and a .300wsm. That power range/diameter is pretty well covered. I have decided to have the barrel re-bored to something bigger as my only big bores are a .358 Win and a 45-70; neither a long range proposition. Even though what I already have will handle elk/moose/black bear nicely, I need to have a reason; so I guess that is what I will use it for. I would want to be good to 400 yards, in the case of a long shot at elk. I would think that with bullets in the 250 grain range, the the 338 will be a little slower and the 375 should be fastest by a 100fps or so. The 338, however, will have a better sectional density and higher ballistic coefficient, and at longer ranges will have higher velocity and slightly flatter trajectory. So, finally we get to the question- am I better off with the higher BC and SD of the 338 or the larger diameter of the 375, or should I split the difference and go with the 358?

Also, I am thinking that the .375/.300 Win should give slightly better velocity than a 375 H&H because, according to my Barnes manual, the Win case has a couple grains more capacity. What do you think?

BTW- The reason I don't just dump the rifle and do something different is that this rifle is the first one I ever bought as a young teen with proceeds from my trapline. I put God knows how many rounds through it (I bought primers by the thousand for it) and the action is now incredibly smooth. Besides that my 'smith does a great job with the re-bores.

acy...We are realy splitting some very fine hairs IMHO. However, if I were facing the same, I "think" I may cast my vote for the .338 for it's "shootability" over the others mentioned.
I also feel sure you may get as many different answers as there Gun Owners, as this question borders on the 270 vs 30-06 debate. I don't know that there is a good answer.
Your thoughts on a 400 yd shot is certainly not impossible for many shooters, albeit a "fur piece" for this old goat. I think this may prove an interesting thread to follow. Good luck on your endeavor.

Thanks Russ. I know I am really splitting hairs here. Probably no real "right" answer to the question. That is what makes the decision so hard to make! I can, at various times convince myself that any one of the three is the best choice- then a minute later... I guess that is part of the fun.

Acy,

Just thought I'd chime in here. I don't know if you read my post about my .338-06 that Al rebored for me. But the 1st 3 shots for group went into .695" outside to outside. Minus .338 = .357" Now we all know that his barrels shoot.

Concerning your dilemma: The .358 Norma is a good one but the drawbacks are that there is only one factory load available. 250 gr. RN. And most .35 cal bullets are meant for less velocity that the .358 Norma puts out. Basically your are left with the 250 gr. Nosler part. the Barnes x bullets and factory loads. Choices are limited. I would vote against the .358 Norma for that reason.

The .375/.300 Win. is fully the equal of the venerable H&H, but you realize there are NO factory loads availble and there are not going to be. However bullet selections if far better than the .35 cal.

About the .338. There's is nothing I can say about that that you don't already know. YOu now have my $.02 worth FWIW...the9.3Guy

The 338 WM is the most practical, useful, shootable and readily available mid-bore for NA use that can be chambered in a moderately light 22" bbl'd rifle, period. You can get fancy and follow your desire wherever it leads you but it really doesn't get any better. Boring? Yep... boring AND reliable just like the 30-06.

I agree with Brad, and like his assessment of a 22 inch barrel. The .338 is like a big .30-06. If animals are larger than 300 lbs, it is my favorite, esp in Alaska, Africa, or elk. There is a guy named Ray who lives in AK and loves it.

The 358Norma mag is the best choice by far. Powerful close and flat shooting long. Actually, many bullet choices. Nosler partitions, grand slams, hornadys, woodleighs and swift Aframe to the elite bitteroots for starters. The norma can be downloaded to 358win power (with lower velocity bullets also) and can be loaded up to 375H&h power with 310gr solids. I even have a beanfield load of 180gr barnes x at 3200fps. Everyone has locked on to the 338mag which is a good round but the 358 is a good deal better and has never been offered by an american manufacturer!! It's special.

Just not many shooters with 358 norma knowledge. Be different.

I can't think of one thing wrong with the 338 Win. Mag., however, give me the 26-inch barrel. The 338 Winnie is probably the most practical cartridge NA, as Brad has already stated. One (if not) of my favorite cartridges out there.

My .300wsm was custom built on a long action Ruger tang safety. I load 180gr XLC's to 3.15"OAL at 3125fps. Groups run around .5" or under with that load. Is the .338 enough different to make it the best choice?

Not really concerned with factory round availability. I rarely shoot factory ammo and at least half of my rifles have never had a factory round through them.

9 3GUY- Glad to hear your .338-06 shoots well, but no surprise either. Al is as good as it gets, IMO.
