Well, I've pretty much sold off my AR's for other things, and am down to two. I was looking at .300 Win Mag upper without much luck, and figured that for the cost of a serbu or other .338lm upper, I could just buy an AR-30. I really want to stick with .300wm over .338 and have also looked at the 700 sendero vs the AR-30. What are your thoughts on something like this for 500-1000 yard shooting. This will be for hitting steel at longer ranges for fun, nothing my life will depend on, and no long range matches or anything like that.

A lot of powder to burn and recoil for just 1000 yard fun shooting. Personally I would look into 6mm or 6.5mm cartridges. A straight .243 with a fast twist barrel is a great 1000+ yard cartridge. Or if you reload go for something like a 6X47, 6XC, 6SLR, 6 Creedmore, 6.5CM, 6.5X47,etc.

Low recoil. All those cartridges only require from 38-45 grains of powder so about half the cost per round to shoot,etc.

Just my opinion. I keep thinking a big .30 or larger caliber rifle would be fun, but then again I would have to drive 2+ hours one way to get to an area where I could shoot past 1000 yards. Where as I am only 35 min. from my 1000 yard shooting area.

Post up what you end up with.

Take care,Stan

The AR30 will be mag fed instead of single shot if that matters to you.

Bigbamboo, I don't mind the cost too much, and already have smaller bore stuff. My next gun is going to be a big bore, and the more I think about it, the sendero is what I'm leaning toward. Affordable, accurate, and I could use it for large game at 500+ yards which is something I can't do with anything I currently own.

I would go the ar-30 route, or the sendero, the recoil from big bore uppers cant be that great for an ar-15 lower.

I'm thinking ar-30 would be more fun, but sendero would make more sense.

I have a 300 win sendero. VERY accurate rifle.

No reason to beat yourself up with a 300 win mag for 500-1k plinking and steel when a 308 bolt would work just fine though.

I had an AR 30 in 338 LM and now have the Remington 700 MLR in 338 LM.

The AR is very long, has an extremely slow lock time and lousy ergonomics. Shooting the 700 MLR is pretty much like shooting any other 700. I think it's more comfortable than the AR too.

The AR brake is fantastic though. Pretty much no recoil. The 700 MLR is pretty good too.

How much was your MLR? I saw one at Ammo Bros and they wanted $2100 for it. It seemed a little steep to me.

If you will be mainly shooting to 1K I would lean towards .300 WM. It will get you to 1K and past it. The AR30, Sendero or even the 700 Police in .300 WM would be pretty sweet.

That's what I used to think. Then, I realized that an AR lower takes more punishment from shooting 5.56 than any bolt action upper can give it. I've got a couple thousand rounds of 50BMG on a FAB10 lower with no signs of wear or abuse.

I remember back when people thought they would egg out the take down and pivot pin holes. I did shoot a .50 DTC upper AR15 and the recoil was a little sharper than the AR50 I shot but I was surprised how controllable it was.

Armalite's MB is one of the most efficent designs so, most other 50s do have a bit more preceived recoil.

I break seperate my upper and lower every time I shoot it and, after 5 years, I still need to drive the pins in with a small hammer.

Yeah their brake is a great design.

What upper do you use?

I have both an AR50 and a Fab10 with an ALS upper on it.

Are they capable of similar groups or does one shoot a better than the other?

I've consistantly noticed about a .1moa difference with the ALS having the edge. I've shot several 5" groups with the ALS and only 6" groups with the AR50. I've also shot them side by side and consistantly had about 1" better aggs with the ALS. All of this has been during record matches and not just playing in the desert.

I bought it a couple of years back, cost me $1,100.00 at Tabors in San Bruno. I see them on GB now for about $1,700.00.

That's interesting. I would of thought the AR50 would shoot better.

Yeah I remember them going for around $1K awhile back and I almost bought one. I read that Remington made some improvements to it a while ago. I wonder if that's what caused the price increase or if they just don't make that many.

When first made I think the 338 LM 700 was called the PPS or PSS - I have a similar set up in the 7mm Rem Mag, can never keep those initials straight. I've handled both and they appear the same - same finish, same brake, same mag system. The older version has a Rem 40X trigger, don't know if the MLR stays with that or their X trigger. If there are other changes such as barrel or how the things are made, a little beyond my abilities when copping a feel in a LGS.:p

I'm not sure what they changes were, if any. All I know is that I want a .338 Lapua rifle but I don't have the skill to take advantage of that round. Or the money to run one.

How accurate are the big bore uppers? A friend of mine wants either a 338 lapua or 510dtc one.

Depends on the upper, the ammo and the shooter. A friend of mine shot a 3 something inch group at 1000 yards with the exact gun pictured here:

I have yet to break the 5" mark with mine.
