And good times were had by all....

Hope you have many great hunts. Please share lots of pictures of far away lands and piles of critters and the stories to match!

You are right about that for sure, this stuff aint that hard. .630" shoulder = use 1/2-28 threads. Not enough shoulder left to do anything else unless you use a custom made adapter to shoulder on the muzzle. The stupid crap about using no shoulder at all isn't worth considering.

The comment about .660" threads above was in reference to what a 9/16-24 thread needs for adequate shoulder.

Also a 9/16-24 to 5/8-24 adapter as shown above is bad juju, they are too thin, minor diameter of 5/8-24 is too close to major diameter of 9/16-24, been there and done that, had it unwind like a spring.

Yondering,

So are you saying 1/2x28 threads with a 1/2x28 to 5/8x24 adapter is better than threading 9/16 and running a 9/16x24 to a 5/8x24 adapter? This on a T3 30-06 finished at .630

That was the reasoning behind much of the previous questioning as it's been suggested both ways, now by the same guy.

Don't do it! Just do it!. LOL

Now it's 0.050" shoulder is perfect but 0.034" ain't worth a chit. No way you can get proper alignment with that. Screw that adapter on there and it'll be all f'd up crooked.... And of course 9/16 to 5/8 adapters ain't worth a chit. Funny Brownells sells them since they're garbage. Fuggin Brownells anyways. Real rocket surgery ain't it.

Yes that is correct Rhettsker, if we're talking about a .630" barrel diameter.

9/16 is good for some hunting rifle barrel profiles IF you're using some sort of muzzle device suppressor mount, direct thread to 9/16, or an adapter to something larger than 5/8. The 9/16 to 5/8 adapter is too thin unless it's extended so one thread is in front of the other and not overlapping, but that's generally undesirable since it's longer. It needs more shoulder than a .630" barrel provides anyway.

No, I never said to use 9/16-24 threads on a .630" barrel. I did say it's an industry standard thread size and needs about .660" diameter to work well, and that it's a good size for a lot of hunting rifle barrel profiles.

Interesting, I have never heard this before. I have a dead air keymo mount, so using the keymo as a suppressor mount would change your barrel threading recommendation from 1/2x28(direct thread recommendation) to 9/16 if using my keymo suppressor mount?

Yeah if you're using a mount of some sort (flash hider, brake, etc) and your barrel has the diameter for it (about .660" or so), 9/16-24 is a better choice than 1/2-28 just because it leaves more wall thickness around the bore. Not all companies offer mounts in that size, suppressors on hunting rifles haven't been very popular or common until the last few years and the "tactical" stuff is generally either 1/2" or 5/8". But more companies are starting to offer 9/16" threaded devices as hunting rifle suppressors become more common, so if that works for you it's a good way to go.

Note - my earlier comment in this thread about shouldering on the muzzle was in reference to mounts like this, I've made them and have seen some commercial mounts but don't remember who made them (maybe ThunderBeast?). If you go that route, a .630" barrel can be threaded 5/8-24 and use a mount that shoulders on the muzzle. FYI some 9mm pistol booster pistons are made that way too, Liberty does them that way for example so a long thread with no shoulder can index on the muzzle.

However, back to the 9/16 threaded mount - the shoulder requirement is still important, so if you're talking about a .630" diameter barrel I think that's a bit small for suppressor mounting. (That's enough shoulder at 9/16" for a brake, I've done that a few times, but a suppressor mount gets loaded more in bending & vibration and ~.035" shoulder is pretty marginal IMO.) I definitely would not go with a shoulder that small for a direct thread mount (repeated installation is hard on a small shoulder); it's arguable whether you can get away with it using a mount that's loctited in place but it's definitely pushing the limits. If you go ahead with that, I'd suggest very tight tolerance barrel threads that are cut to match the muzzle device.

If you have the option when the barrel gets threaded, adding a shoulder as gtscotty's pics show above is smart. It can be smaller and less obtrusive than those pics, but regardless it's a fairly easy thing for most decent gunsmiths to do. As long as it's locked in place well (loctite, solder, epoxy, etc) and then trued up it's a solid way to go.

About that 9/16-5/8" adapter - the minor diameter (meaning bottom of the threads) for 5/8-24 is .574", while the major diameter of 9/16"-24 is .563". That only leaves about .005-.006" solid material between the two threads so the adapter is not very strong. I had one fail when it was tightened down; it unwound like a spring and caused some minor damage to the suppressor threads, so it's not worth taking a chance on IMO.

Hope that helps.

Post above clarifies...

Ok let’s get back to rifles. My open country suppressed setup:

That one checks a lot of boxes. Nice rig.

Yondering,

Very helpful explanation--thank you. Kimber7man, what are the specs on your beautiful open country rifle?
Thx, R

Omega pattern 9/16x24 DT mounts have been scarce for a while with SiCo often being out of stock. Energetic Armament has come out with a run of 9/16x24 Titanium DT mounts that will work with cans with the 1.375x24 mount thread like the Omega 300, Vox S/K, Nomad 30, Rex MG7, etc.

Omega/Nomad/Vox 9/16x24 DT mount

Just wanted to give other suppressed hunters a heads up, looks like a limited time thing, so I ordered mine right away.

Thanks for the heads up!

I killed 7 pigs with suppressed loads last weekend, they are fun to shoot, no noise, no recoil!

Spot on with information that wasn’t asked as per usual. Can you tell us now about which wax you use on your boat?

R,
Thanks, That is a G.A. Precision Xtreme Hunter 6.5 SAUM. Only upgrade from the standard model is I went with the Jewell trigger. S&B PMII 10x42 fixed scope, in Talley lightweight lows. Several guys here on the campfire have them. George Gardner, Pat Sinclair and Scott Shreve started us off with brass trimming and load development back in 2012/2013.

I took the Vias brake off, bought a custom 1/2x32 to 5/8x24 threaded adapter from Mark at TROS, and screwed on the Ultra 7 6.5 CB.

Thanks very much. Just a beautiful well thought out rifle.

Nice rig Kimber7Man. Be Well, RZ.

Hanco and a post with substance... surely you jest.
