LMT .308 MWS?

[Jpach]

Mine didn't direct from LMT. The ambi release is present but disabled somehow. I havent taken it apart to see how.

I had my upper and lower shipped to my FFL in separate pieces. All you have to do is punch out the roll pin and the ambi mag release comes right out. I wish I could have it in though!

K, the ammo I used was hornady custom sst 150gr. The box says 2820 fps.

I assume their fps estimate is with at least a 22" barrel.

Someone else can work the numbers but I'm pretty sure there is much more drop from a 16" barrel than a 20" beyond 250 yds.

I did some searching and the consensus seems to be around 25fps per inch of barrel, although it really depends on the individual barrel.

I used the 25fps as an approximation and ran the Hornaday SST through Ballistic at 2820 and 2720 fps. Here are the results.

Yeah I dont believe that. I was tagging a steel plate at 650yds with a 3.5x acog in side gusting wind 25mph. FIRST HIT FIRST SHOT. I could have gone to 1000k with a more powerful scope.

Some folks like to shoot things FAR away.

A 16 inch .308 is okay for stuff up close (say... 300-500 yards). But beyond that, a longer barrel and the added velocity it brings helps a lot. A good .308 rifle with a 20 inch barrel can throw bullets pretty darn far (1,000 yards+).

And with the LMT MWS, you have the option for a quick barrel change to an even better caliber, like 260 Rem or 6.5 Creedmore if you send it to the folks over at DBMG.

I was at Bullseye in San Rafael. They have a LMT MWS and the REPR both in stock as of today.

If those figures are good, then a longer barrel "might" have helped me. A 2 to 3 inch difference does not seem like a lot at 400yards. But maybe it is?

Using your 25fps loss I'd be curious if 2770 vs 2670 made much difference.

I called them just a minute ago and they don't have them in the .308. What's the other diffrences is there With the new enhanced version compared to the Gen 2 version.

That chart is not right. Is it showing 57ft-lbs of energy at 500yds?

Repr gen 2 had a "CORRECTLY" sized magwell so it would feed ammo.
LMT gen 2 had new BC, new bolt, new upper
LMT gen 3 has slick side rails and ????

One last thing to keep in mind. The wait times for guns are going to go out to infinity as the election grows closer. Buy now and have a bird in the hand.

What don't you believe?

That a longer barrel and more velocity are better for long range use? That is a fact of physics and ballistics.

I didn't say a 16 inch barreled .308 LMT MWS couldn't be used at long range. I said a longer barrel providing more velocity is better, and it is.

[Omega13device]

You're not reading it right. The dashed lines plot the energy and the scale is on the right side. The faster round is delivering 1114 ft-lbs at 500 yards.

So I'll be ordering my .308 in the next week or so. What kind of scope should I get? I would like a NF but man they are expensive and well after the rifle it might take me a while to come up with the cash.

[Knife Edge]

I have always wanted a longer barrel rifle. I have a .223 with a 16" all ready and just feel like I would be happy with one.

One question. How does a BB take care of the ambi mag release?

A world of difference between a .223 in 16" trying to throw 69 to 75 grain bullets and a 16" .308 throwing 168 to 178 grain bullets, not even in the same league when looking beyond 600 yards.

.....I said a longer barrel providing more velocity is better, and it is.

You wont gain as much velocity as you think, more or less based on the type of powder used. Some of the faster powders like XBR show minimal change in velocity from 16" to 18", however 18" is probably the ideal length considering OAL of the firearm and maneuvering it; 16" having an advantage offhand which is where you will likely find yourself hunting at 100 to 150 yards. Loads of shooters take the 16" OBR to 1,000 with 175g SMK or 178g Match, the theory a .308 isn't a 1,000y gun is a myth that's been busted over and over. If I had to buy an OBR again I'm not sure I could decide between 16 and 18, probably whatever was in stock. With the LMT its obvious, something smaller than .30 to get the BC up and that's where the advantage is hidden. Remember, you aren't building a bench a gun and loading the bullets to a few thousands off the lands, tuning the load, etc. in order to make one ragged hole at 400 yards, you are buying a great run of the mill medium range platform that will shoot long range but at a disadvantage with gusty wind or ranging errors.

Just my .02 and trying to help another .308 guy. FWIW, I had all the same thought processes as you. The average operator will tell you to put a 3-15NF or 4.5-14 Leupold on that gun with an angled RDS for CQB work. 15X is more than enough for 1,000y and steel work. Some of the newer Mark 6 Leupolds are really opening up the window with 3-18, even better but more money. FWIW, buying a graduate level .308 gas gun (OBR, LMT, custom) is deserving of an equivalent optic, optics are everything and often times cost as much as the gun. The Leupold Mark 4 ER/T M5 4.5-14x50mm can be found for $1350 with enough searching around; it's first focal plane, TMR reticle, mil turrets in a beafy Mark 4 scope housing with all the best optic treatments. The Leupy is about $1k cheaper than an equivalent NF but the NF has the zero stop feature, not a factor unless you are shooting in the dark and don't want to give away your position using a flashlight to read the settings (IOW, you reset to zero and count clicks). Most medium range shooters won't notice the difference in clarity between Leupy and NF if you were to put paper trash bag over the two scopes and look through, both have sufficient clarity to shoot under moon lighting with no light amplification optics, NF has a FFP illuminated reticle; again stuff you will never need unless you get paid to do that. If you an afford the NF, by all means you won't regret it. If you can't, get the Leupy and your kids will still tote it to and from the range, still under full warranty decades from now.

lates!
