Guns Like firearms themselves, there's a wide variety of opinions on what's the best gun.

I like my 300 Wby kick is not bad and in my Sako it is very accurate. The cases seem to last too must be the double radius shoulder. After looking through the reloading manuals it seem to be very close to max speed for a 30 cal. It uses less powder that the RUM as well. This is just my 2 cents but great topic.

I've been fighting the urge to build this as another 338Lapua... Just seems too vanilla... But pretty hard to argue with availability...

Why fight the urge? You know you will lose in the end so why struggle? "If you build it, they will fall"

Default Edge or Lapua?

The Edge was one which I hadn't appropriately researched, but after it came up in this thread, I corrected that lack of understanding - I had previously assumed the Edge was only slightly faster than the 338-300RUM. Apparently it's a bit more than "slightly" faster...

So... Cases aren't cheap nor widely available for either, but 338 Lap brass seems to be readily available off of the shelf (not to mention factory ammo, should I ever be foolish enough to pay for it), rather than being wildcat brass.

On the other hand, I've had a Lap, haven't had an Edge, and it's a little cheaper to get a RUM ready action than a Lap ready one. Looks like dies are out there on the shelf... Kind of a non-wildcatter friendly wildcat...

Is it 6 of one, half a dozen of the other? Any reason I might be missing to go Lapua vs. Edge, or Edge vs. Lapua?

Nothing wrong with either. The Lapua of course will have better brass.

The Edge is a 338-300 rum so I'm not sure why you're seeing higher numbers for the Edge? Maybe you're looking at the Edge+P?

Don't overlook the 338-378 Wby or the Lazzeroni Titan either..

What I had seen in the past for the 338-300rum, which I think a lot of folks call "338 RUM," is a goodly bit shorter than the Edge, which is why, as I understand it, Shawn differentiated the two and titled the "Edge" as he did - since it has the "edge" over the concurrently developed 338 rum.

I also saw some interesting data, not sure it makes sense to me - I saw a claim the Edge has a 122grn h2o case capacity. This was compared to somewhere in the 114grn ballpark for Lapua, and 103-4 for 300rum, hence not making sense to me. Seems like an awful lot of growth for a simple neck up, and if it really has 8grn more capacity than the Lap, I'd expect it could outrun it, not just tie.

I'm far from decided upon which it'll be, but it didn't take much persuading to kick me out of the 7mm and 30cal boat for this build to focus on a 338.

As a die hard .416 Rigby fan, that's an angle in my head where the Lap has an advantage, even if it means absolutely nothing, objectively.

The 338 Edge is a simple neck up, a 300 RUM to 338.

The 338 RUM case is shorter then the 300 RUM case.

That's why Shawn used the 300 RUM case for his Edge, just to get the "edge" over the factory 338 RUM.

122gr capacity for the Edge is a bit high, it's right at 115gr.

It's all splitting hairs as far as performance, not an animal in the world will know the difference.

I would personally skip the Edge and just go with a 338 RUM, but if I could get any 338 cal it would be a Titan or Snipetac!

yeah the 338 rum is 100 thou shorter than the 7mm or 300 rum, just like the 300 winny is 100 thou longer than the 264 and the 338 winny's. as allan said the 338 edge is just a simple neck up, not sure what the difference is in the +P version, the 338/300 Rum IMP. is known as the 338 O'Brian.
