USA vs USMC

[duey1267]

I have a question regarding the choice of rifles for out military. I was told that the USA M24 SWS uses a long action Remington and that the USMC M40 sws uses a short action Remington. Is there a logical reason for the difference?

Thanks Duey

The Army chose the long action so that it could rebarrel for .300WM if it later chose to do so.

He is correct. I believe the new PSR for the US Army will either be .300 WM or .338 LM.

Is this moving toward a "theater" mindset with M110 for urban and magnum M24's for mountain/desert?

I'm surprise the AMU hasn't looked at the 300WSM. Shorter action, just a different bolt. Be able to cycle the bolt quicker with less body movement and a stiffer action.

Re: USA vs USMC

Aside from converting some M24s to .300 WM, the Army - and the Marine Corps - are also looking at .338 Lapua Magnums for extended distances.

Given the superiority of the .338, and the small difference between the .300 WM and the .300 WSM, I'd be surprised if there was serious consideration in either service of a rifle based on the .300 WSM.

Basically. My understanding was "more tools in the toolbox".

Two bad. Barrel life would be extended and you could do away with the (hate to say this) 308. Just go with a lighter bullet. Bullet range weight 150 to 220gr. I guess they have a lot of 300WM lying around.

Re: USA vs USMC

Oh, there's more than that. The military has a new .300 WM cartridge to extend the range beyond what the previous load does. It throws a 220 SMK. See:

Re: USA vs USMC

there will have to be some serious logistical changes if a full blown caliber change is ever implemented. there are many instances in the latest theaters where snipers had to de-link mg ammo just to stay in the fight. tough to find .338lm or 300wm laying around when you run dry of the match stuff.... my .02

Lindy, are you with Graham that this is possibly a cost effective stop-gap until the gavel comes down on the .338LM?

 

[Lindy]

Re: USA vs USMC

Graham and I disagree infrequently. This is not one of those rare times. And besides I admire his taste in Scotch whiskey.

I suspect the military .300 WM sniper rifles will be around for a while.

I assume that we are all single malt guys here,yeah?

Re: USA vs USMC

Yeah.

Another group of Scotch aficionados is the docs from Team WaffleIron. They travel with great scotch and elegant crystal glasses. I sit humbly at their feet - begging. Fortunately, they are kind fellows.

I'm partial to Laphroaig, myself... I like the smoky taste. goes really well with smoked salmon. That is until the whole thing lights up and you get 'hot-fire' in the tummy from grease and smoke.

Does the .308 feed reliably from a long action?

If it didn't the Army would've canned it long ago. There are plenty of people running short calibers in LA's.

I'm collecting parts for a 7-08 in a LA, won't be able to build it 'til late next year but.... I'm collecting parts.

Re: USA vs USMC

The long action M24 can be a wee bit tempermental. When loading and a newbee you have to consciously pull back on the bullet tips with your fingertip and seat them all back. It becomes instinct soon enough. (Oddly enough, when shooting M700 short action, it sometimes seems out of sorts to use...)
Loading has to be done in this manner otherwise some failures to feed can occur, though rarely.
Some, rarely, switch out to DBM.
Overall, it is a reliable system though slow to reload especially for combat.

Loading all the Mauser actions that I do it's second nature to load pushing down on the case body just behind the shoulder then shoving the shoulder all the way to the rear while the case is depressed.

The taper of the rounds, no matter what case you have, or have formed, is what makes them not feed correctly. The follower and rails are (hopefully) milled/cut/filed to feed the specific round you shoot. That can only work if your case head starts at "0", the back of the magazine. Just like always "tapping down" AR mags.
