Shooting 6MM SLR? In AR-10/LR 308 platform?

[Darryll]

Is anyone still shooting the 6MM SLR? Has anyone built it on an AR-10/LR 308 platform?

Are there any gunsmiths that would consider building one for me?

Thanks, in advance!

Yes and Yes, but I havent shot it in a while. I chambered it myself, I liked it but didnt get to play with it as much as I liked. Id do it, was very easy to shoot and load for.

Yes, my practice gun is a 6SLR bolt action shooting 115DTACs. My load is 45.1 grains of H1000 which gives me approx 2930 ft/sec out of a 30" barrel. I could get more velocity but accuracy is good and I'm trying to get decent barrel life. If you shoot a slow powder I highly recommend large primer brass. When forming the SLR from a 243 case if the brass shoulder thickness is heavier than the neck doughnuts will form. I've been using Sig-Sauer 243 brass and haven't had a problem. Its pretty good reasonably priced brass if you can find it. My COAL is 2.90 with the bullet bearing surface just a hair above the neck shoulder junction so you might have issues shooting the long 115 gr bullets from an AR magazine.

I love me anything SLR

Shoot a 6XC, which is close, on an Ar10 platform. Scott Medesha did the work years ago.

Just my experience, shooting that round in a bolt gun vs a gas gun is huge. Getting reliable functioning in the gasgun requires a bit of work. I second Scott Medesha if he is still doing that sort of work. He did my AR-10T in 6XC and it shot well in NRA XC competition. Did take some work to get the functioning correct with an adjustable Buttstock.

PS. Read the section on the SR-25 in Tubbs HP book to get an overview of some of the issues n fixes.

Mine worked from the start. I put an adjustable gas block on it and turned the
screw till it was 100% reliable. As always YMMV.

An adjustable gas block is certainly a step in the right direction To control carrier velocity. Have u modified how far ur carrier recoils? Excessive clearance Between the carrier in full recoil n the bolt stop gives the full weight of the bolt n carrier a run at the bolt stop. This clearance needs to be minimized as sheared bolt stops can be the result.
just a couple of thoughts as u take this journey.

I just put one together. Bolt gun though. One issue I've had is neck clearance. Ive got a 275 neck which I read was a no turn neck. Hasn't been the case for me. Between the winchester, federal and sig brass I already had I've ended up turning the brass to .0140-.0145. My loaded rounds are now 271. But so far I'm enjoying the cartridge.
