Are you thinking of a 338 edge? read this

[sinman]

The 338 edge is made for long range shooting/hunting because of the high BC bullets the speed of a rocket. A lot of people are shooting 300 gr bullets with around 95gr of powder which means recoil and a lot of powder being burned. A lot of people over look the 7mm wsm for a long range round so I decided to post this.


The 7mm wsm with a 180gr berger bullet at 2800fps has 330" of drop at 1000yrds and 60" wind drift with 10mph 90degree cross wind

The 338 edge with a 300gr Sierra bulllet at 2700fps has 334" of drop at 1000yrds and 52" wind drift with 10mph 90degree cross wind


The 338 has more energy of course but the 7mm still has over 1000lbs of energy at 1000yards which will put down just about anything you would be hunting. So when you decide to go for long range shooting make sure you check out different cartridges you might find one that will work better for you, or at least not beat you up so bad. But if you still want an Edge I love building them haha Just some food for thought

[sinman]

almost forgot a really important part, the 7mm wsm can be a repeater in long and short action depending on bullet seating

[geargrinder]

I'll also add that the 7mmWSM has much better brass than the Edge. Winchester brass is good, but Norma brass is a simple fireform away. With the Edge you're stuck with soft Remington and even softer Nosler.

Berger bullets aren't the top of the pile for 7mm either. Wildcat Bullets in Elko, Nevada makes a great long range hunting bullet that weighs 200g. It's a VLD style with a rebated boat tail.

That reminds me. I need another 7mmWSM barrel. Dang you Devin. You made this post on purpose. ;D

[sinman]

I might of haha, actually you might need another edge too haha

Don't laugh. Another Edge is already in the works. I'll be in touch.

[dcloco]

Agree with your info.

Heavy 30 calibers do rather well and are so overlooked, because it is not "trendy". :)

30/06 or 300 Win Mag with 180 to 210 gr bullets are very capable as well.

Of note, I agree with the summation that 95-100 gr of powder behind a 285 to 300 gr bullet is punishing, regardless of the weight of the rifle. A brake is a must have with that much powder and weight of bullets.

IMHO, why build a 338 RUM or Edge or Lapua....if you don't plan on stretching things past 1200 yards?

Do you need a certain 'shank-size' action for the 7mm WSM (large shank ?) or will a barrel like this fit my model 12 F/TR ??

[sinman]

You can build on either shank size and yes it would work on your savage.

What is the diference between a 338 "Edge" and a 338 RUM?

The Edge it based on the 300RUM which is about .09" longer than the 338RUM. It gives about 100fps more.

The 338 is the red headed step-child of the RUMs. The 7mm, 300, and 375's all share the same case design.

[khuff]

So Sinman, what your really saying is I need to build one of each......LOL.

Your right! I have a 300RUM large shank Savage, timed and trued by Fred, that I need to do something with, I plan on taking my time and doing it correctly. I believe you made a 7WSM barrel for it and it was sold separately from the gun.

montana_native is selling one in 338 Edge that is pretty much what I want (or thought I wanted); I'd like to build a 7WSM on a AR10 platform (LR308 lower) I have(instead of 300WSM or 338Federal) as well. Sinman, I know you've well versed on 338s and I think you know ARs rather well.

What are your thoughts of these two rifles? Do you know of anyone that would get me the barrels? LOL

[sinman]

I have had my hand in a few ar15 barrels, no ar10s (yet). I have made tons of 338 edges and I am working on a new 338 Sin that works as a repeater for Savages on a Std mag action. I am someday going to build a 7mm wsm on an AR 10 for myself and maybe even a 338 wsm too. Being able to have 10rds of 7mm wsm ready to unload in a mag as fast as you can pull the trigger is something I could really like. Khuff send me a PM if you want to do a 7mm wsm ar10 and see if we can work something out on a barrel.

[Tim300wsm]

what case arebyou going to base the 338 sin on?

[geargrinder]

I believe it is going to be a shortened RUM case. Then it will be fireformed to the correct shoulder and wall dimensions.

[CRNA]

So, what would be wrong with the 7mm Rem Mag? I decided to go with the Rem Mag just because they are not supposed to "burn up" barrels as fast as the WSM. Any thoughts on the pros and cons when comparing the WSM and Rem Mag?

[geargrinder]

I don't believe that there is any way to prove that the 7mmRM is easier on barrels than the 7mmWSM. They shoot about the same velocities and use about the same powder.

There's absolutely nothing wrong with the 7mmRM. It's a very fine round.

But, there are some advantages that can be had with the WSM. Especially if you're using it in a long action. The biggest is that you can seat the long range bullets out to the lands if needed.

[CRNA]

Oh, ok, I see what you are saying.

[nhm16]

If you have a 28-30" barrel, you can shoot a 180gr Berger at 2850fps with a straight .284 Win., and gain Lapua brass and 2000+ round barrel life, shot in f-class match conditions (22 round strings). Lots of guys at my local f-class matches shoot a straight .284 even faster than that, at around 2900-2950 fps. I have a 30" Benchmark chambered in .284 and PR&T/Savage Doctor stock waiting on an action from SSS that I intend to shoot at around 2850fps.

F-class shooters are driving the 7mm WSM (or 7mm-300 WSM) to around 2950-3000+ fps, or even faster, though due to the very short barrel life, nobody I know shoots one.

Also, Berger now also makes a 7mm 180gr Hybrid that is similar to their .338 300gr hybrid that has an even higher BC than the 7mm 180gr VLD, and is less fussy about seating depth.

Another round to consider is the 7mm RSAUM, which sits almost exactly halfway between the .284 and WSM cases in capacity yet can achieve velocities very close to the WSM With less powder.

Though to be honest I also want a big .338 for no reason at all ;D

[barthmonster]

I'm liking what i read on 6mmbr.com about the 7mm SAUM, all except rem brass but they said it's very good...

[barthmonster]

As a reloader, I'm not fond of the belted-case that's why I have a 7mm RUM and I would like either an Edge or 300 RUM or possibly 7mm WSM, something along those lines.
