You have made 1 statement in that chapter of this thread that really covers it all.

I feel passionately that the 338 LM does have its place in a high threat environment, but I don't agree that it is the magic bullet answer.

As I said in post 16, there are quite a few PGWDTI Timberwolf's in the US military, and the Canadians are coming up to their 2 year anniversary for issue as the intermediate sniper rifle. (Also a picture in post 16).

I also stated that the brake reduces the recoil to that of an FAL.

FWIW: The first sniper kill with the C14, (Timberwolf in the Canadian Army), was made last February in A'stan at 1500 meters.

The .308Win has it's place, as does the .50BMG, but so does the .338LM.

The Edge will never (IMO) be a miltary round because it's a wildcat, there is no brass availible unless it's custom and it has no CIP rating. That's not to say that it isn't a good cartridge and I admit that I know little to nothing about it except what I have gleened from here.

My #1 choice would be the .338 Lapua for out to 1500 yards, the Brits and Canadians have proved it works very well. Remington will be making rifles chambered for it, and I think its the real winner here.

Not as effective at 1500 yards as the .338 Lapua but certainly good to way past 1K would be a 7WSM or 300 WSM.

A little less costly than a .338 Lapua would be a nice 10 twist 300 RUM firing something on the order of a 240 SMK, that would also be quite effective. Not a favorite of mine but a 338 RUM is no slouch either.

Although some of the Wildcats mentioned would be very good as well, I don't think Uncle Sam would even consider them.

I don't thinks a 7mm is what they would want. I think they'd what 30 cal or bigger. Just my thought.

It's still supersonic at 1500 yards, barely.

Would make a nice 12lb to 14lb rifle with a 24" barrel.

The 260 Rem shooting a 140 Berger at 2,700 fps.

Lower report
Lighter rifle
Lighter recoil

Shooting to 1500 yards is all about the bullet. You need a BC approaching .7 or better, and about 2900 fps MV, to get there in style.

The 7mm 180gr JLK VLD has BC .735. Launch that bullet at 2850-2900 fps and it will deliver more to 1500 yards, than the 308/175 SMK delivers at 800 yards, in terms of retained velocity/energy.

A 24" 7mm WSM could do that very handily, and avoid the huge dust/noise/flash signature of a big 338.

I think the 338 and 50 have their place for special uses, but the 7mm would be a quantum leap forward for the everyday sniper in the field.

Help the Marines......

decide on a new rifle/caliber?

HORSE-KRAP GALORE!! NO WAY!! Jesus Christ Himself could come down and tell 'em what to use but there would be some 'pissy-assed' General from somewhere that don't know whether his arse has been punched, bored, or eaten out by a woodpecker and he'd know as much about marksmanship as I'd know how to perform a lobotomy on someone's brain and he'd be one of the REMF that would tell them what they would need!! My deceased friend Carlos Hathcock had it right in his book when he stated...."There aren't enough men in the upper echelon of the military today that understand marksmanship enough to make up a baseball team!"

Truer words were never before spoken!! I lost any faith that I once may have had in our military leaders when they 'rolled over' and let the DA sluff off the damn M16 on the Services because that's the worst POS that ever came down the pike for a Service Rifle!!
