Pics are good...

Story???

[crawfobj]

Nice! Details please!

[MT Chambers]

Okay here goes......once I had a Ruger bolt gun that didn't shoot worth a $%^&, so I put a 300 Blackout barrel on it, because I wanted to be different then everyone else, I'll let you know how it shoots.

[KinkBreaker]

whoa. ok
i actually bought the ruger especially for the project, it has not been fired yet even as a 223rem.
what i wanted was a bolt rifle that i could use with the suppressor i already own. its a 45 acp suppressor, i would have really liked a bolt gun in 45acp but it seemed like all the options would have been hokey in one way or the other.
i decided to go the 300blk direction for the subsonic deal.

the other ruger bolt actions i own are pretty decent for accuracy, i would think this would do pretty well too

perhaps liking rugers makes me seem like i just want to be different

the barrel is from mcgowan (http://www.mcgowenbarrel.com) i had it shortened, recrowned, and the muzzle threaded at palmetto arms llc (http://www.palmettoarmsllc.com)

[KinkBreaker]

sorry there wont be any how it shoots until i can get an optic for it

[MT Chambers]

Good, your story sounds more plausible then mine! I just don't find the cartridge as accurate as some and my experience has only been with boltguns.

[KinkBreaker]

this is my first 300blk. and it is my first rifle that you couldnt just go get catridges at the walmart if you wanted

[Jailer]

I've often thought about how a Ruger would do converted or re bored to 300 blk. I have a savage Axis converted to 300 blk and I really like it but ejection is still hit and miss.

The Ruger 223 is a pseudo mini mauser action with a fixed ejector and claw extractor correct?

yes correct, clay extractor and fixed ejector mauser style. aka controlled round feed

[Jailer]

I think a laminate compact re bored to 300 blk would be the bees knees.

Or better yet a gunsite scout copy in 300 blk so you had open sights. With the effective range of the 300 blk cartridge open sights would be a perfect companion.

[Jailer]

Now you've peaked my curiosity. I like my savage but I can't wait for your range report on the ruger.

Not accurate???????

147gr pulls. Only 3 shots but a typical result for these.

Nosler 125gr Ballistic tips and 18gr of H110. 5 Shots this time.

[MT Chambers]

But wait my accurate friend, accuracy with cast boolits is what matters to me, or at least that is what I was referring to.

[KinkBreaker]

got some pics to put on later.
was out at pipehands house on sunday, after spending a few shots sighting in at 50 yards the rifle seemed to be making pretty tight groups with the lee 230gr and 9 grains of lilgun but it turned out that was supersonic

also it was hot outside

[Smoke4320]

I am down to 7.9 Grains of Lil Gun 10.5 barrel and a YHM Suppressor in an AR and its right on the edge of subsonic ..
in the winter it would be subsonic above about 70 and its pushing 1050 to 1065

From yesterdays range trip. Not as good as jacketed but still good, especially for just throwing together the loads, IE: no weight matching, case sorting etc. It was good enough to repeatedly ring the 200 meter chicken and 300 meter pig.

Printer/scanner is acting up so I had to take a pic to upload.

[MT Chambers]

Nothing wrong with that! I have similar rifles built and are mostly custom with target barrels, Jewel triggers, etc. One is a .300 Whisper, the other a .30 Br., and the Whisper (Blkout) can't touch the .30 Br. in terms of accuracy and just to confirm this, another Br., a light hunting rifle, outshoots the Blackout...just a more accurate round and in a boltgun, the Br. is a much better choice.

[Jailer]

I need to do some stock work to stiffen this thing up. It is very sensitive to where you bench it and it groups like this pretty consistently across different loads. Rest it anywhere forward of the front ring on the action and the groups turn into patterns.

That's my main reason for my interest in this thread as well as how Kinkbreakers Ruger does with functioning.

[W.R.Buchanan]

KinkyBreaker: go to the "swapin' and sellin'" forum here, and seek out "Grumpa." He makes .300 BLK brass.

[hound_dogs_01]

not bad. how "quiet" is it?

[pipehand]

Hound Dogs, I don't know when KB will be back to respond, so I'll field this one for him.

The load of 9 grains of Lil'Gun was supersonic to the tune of 1200+ fps, so there was bullet crack. On the other hand, I was amazed at the lack of report considering the 30 cal boolit was being shot through a 45 cal suppressor. I can't wait for another opportunity to shoot it with some truly subsonic loads. I'm thinking it should be quieter than some pre-charged pneumatic guns.

[Jailer]

Any updates? Hows accuracy? How is function? Does it extract and eject reliably?

[Jailer]

Any progress on this?

[KinkBreaker]

yes and no on any progress.
i lost the pictures of the first sets of targets, but the initial results with available ammo werent great.

factory remington loads 220 gr, poor accuracy also not subsonic
230gr lee mold 9gr lil gun, poor accuracy not subsonic ?
147gr fmj pulls 14gr 4227 poor accuracy not subsonic but werent meant to be.

as soon as i can get back to loading for this thing ill be all over it

[KinkBreaker]

have you got load with the 230gr lee bullet?

[pipehand]

I don't remember the 230 grain accuracy as "bad". What was bad was the same boolit in a Ruger 77 7.62x39 using 6.5 grains of red dot. Was more than likely subsonic, but they grouped like I shot them from a slingshot. Same kind of holes in the paper-sideways. Same boolit, same gun, with 11.5 grains of 4227 made a nice round group at least as good as any other plain based boolit I've tried in a nominal 30 caliber.

All the published subsonic data for the Blackout has been for jacketed bullets, and more than likely, for semi-auto function. With your bolt gun, you're not limited to ensuring a set amount of gas to work the action, so you can use faster powders. Still have some Green Dot left? You can also try the lighter molds, and still remain subsonic.

[Jailer]

have you got load with the 230gr lee bullet?

I haven't tried the 230gr Lee boolit in my gun. Most have reported not so swell accuracy with this boolit. Some have reamed the boat tail out to a plain base and have gotten better results.

You've got a bolt gun, take advantage of some fast pistol powders. I've gotten excellent results with the Lee 312-155-2R no gas check tumble lubed with 45/45/10 and 4.8gr of 231. 1080 FPS +/- 6 FPS and ragged hole accuracy at 50 yards. Unique would be another great choice especially with the heavies.

What is the twist rate of your barrel and how is the extraction and ejection?

[Jeff H]

.......You've got a bolt gun, take advantage of some fast pistol powders. I've gotten excellent results with the Lee 312-155-2R no gas check tumble lubed with 45/45/10 and 4.8gr of 231. 1080 FPS +/- 6 FPS and ragged hole accuracy at 50 yards. Unique would be another great choice.......

I just started experimenting with a Handi/AAC 300 BLK (1:7 twist) using cast and faster pistol powders. So far, I have shot 5.4 grains of Unique with a LEE 170 grain FP, tumble-lubed, skipped the gas check. At fifty yards, I shot a few three shot groups that were under a half inch using a 4 MOA red dot on a 2" bull. Next time I shot was with a cheap 2x shotgun scope and the cross hairs are as wide as my 2" bull so I didn't shoot as well as with the red dot sight. I have not chronographed it yet.

Next will be W231 behind some LEE 113 grain FPs, tumble lubed, with and without the GC. Will probably try Unique with that one too.

[KinkBreaker]

its 1:8
extraction great
ejection is interesting. if you pull the bolt like you mean it, it will toss the casing a couple feet away reliably. if you reserve the way you pull it back at all it just tips the case out at about 30 or so degrees. i kinda like it this way so far so i havent tried to mess with the extractor any

[Jailer]

Bumping again for an update. Sorry to bug you again but have you tried any other boolits in this yet?

I recently acquired a HM2 Harris designed mold and I'm having feeding issues with this boolit. Have you tried any other cast boolits in your gun? I'm curious to know if you've had any feeding issues with different bullet profiles. Anything other than a long round nose or spire point won't feed well in my rifle and I'm curious if you've run into this with your gun.

[pipehand]

Jailer, I recently bought the subject rifle from Kinkbreaker, and was only able to do a little bit of experimentation. Light loads of Unique would keyhole the Lee 230's, but shot fine with the Mihec 308 hunting hollow point. 11 grains Reloader 7 shot the 230's and others accurately.

I stopped by a Harbor Freight store this week, and they had the 2" cutoff saw on sale- but it was out of stock and they won't have any more in till this coming Thursday. I got dies and some converted brass with the gun, but need to turn a few hundred 5.56 cases into Blackout.

The suppressor did not come with the gun. Trying to source a dedicated 30 caliber, user serviceable, full power 308 capable can. I got to look at a few cans at a local Class III shop, but only the pistol cal cans were take-apartable. Some samples from Innovative Arms out of Elgin,S.C. looked promising, and the dealer said the guy running Innovative is working on a user serviceable can. Will have to contact him.

Asked same dealer about the Tax Stamp process, and he was very helpful. Said that individual transfers are taking over 12 months in some cases, but trust transfers are running 90 to 110 days. Dealer has a lawyer contact that can draw up the required paperwork for $150.

So far I haven't run anything over the chronograph, but there is definitely no sonic "crack" with the heavy boolits and 11 grains of reloader 7. I also have a model 77 in 7.62x39 but the 1:10 twist needs the Lee 230's to be going faster to stabilize. I haven't considered trying the 230's in my 308, as it has a 1:12" twist. If I can get the suppressor I want, all my 30's are getting 5/8x24 threads on the end, and I will get the thread adapter to allow the 30 cal can to mate up with 1/2x28 threads for use on my 5.56mm AR's.

I'm pretty occupied with work right now, but as I can make progress with the latest project gun/cartridge, I'll post.
