hey guys, just thought i would start a thread for bolt gun lovers. i just had a savage model 11 hog hunter .223 rem converted into a .300 blackout!!! it has the factory savage accutrigger and stock, utg 20 moa rail, swfa ss 10x42, 16 1/2" fluted kreiger barrel, and a yhm qd phanton 7.62 suppressor. i am using rp brass, 220 gr smk, cci no.400 primers, and 10.6 gr of AA 1680. with a coal of 2.22.... it is shooting a 5/8" group at 100 and a 1 3/4" group at 225 yds. what is everyone else getting?

I am presently mulling over getting a NEF Handi Rifle in 300 Blackout and threaded for a 30 cal can I have already. One of the members here has one and made a video of it being fired. I already have several NEF SB2;s and just need the barrel so I would get out of this rather inexpensively I would think. Or I am going to get one of my 308 barrels threaded for the can and download the 308 subsonic. Do you know other than the ability of using the ammo in a firearm designed for 223/5.56 for magazine size is there an advantage over a subsonic 308 round?

Sounds like a cool rifle.

well i am new to this cartridge as well, but i can say this, it is an accurate round, you can either buy the factory brass or make your own from .223 brass. you will use very little powder as i am using 10.6 grains of AA1680 or reloader 7. also you can buy factory supersonic and subsonic ammo. i too have a savage .308 pc on the way and cant wait til it comes in.

The bolt rifle sounds interesting.

My 16" AR has not been as accurate with supersonic loads. 155 AMAX with AA1680 has been the best with 5 shots groups ranging from .9" to 1.5" plus at 100 yards. Most of the time I get 4 tight shots with a flier so I am hoping it is me.

I am getting 1.5" to 2" groups with Speer 125 TNT and H110/W296.

The Sierra 125 OTM made for the 300 BLK won't hit the broad side of a barn from my rifle, either in factory ammunition or my reloads.

I might have to try the subsonic loads.

farmer, if you can do that well with the blackout, why did savage can their rifle due to accuracy issues?

[OHShooter]

I have a Savage 112 single shot rifle and a CVA Apex rifle in 300 Blackout and a Gemtech Sandstorm suppressor. I haven't tried either on paper but can smack steel plates pretty regular at 100 to a little over 200 yards with both of them. I've used both Remington factory sonic and subsonic rounds and two or three different hand loads. The thing is silly quiet. Even the factory sonic loads are fairly quiet. The echo coming back from the tree line is louder than the report of the round going off.

I have "heard" on the internet (and we know how reliable that can be) that subsonic 308s don't work all that well. I can't say for sure right now but in the next couple of weeks I hope to get a Savage Model 10 FCP and give them a try.

Even if subsonic 308s don't work, regular sonic round should be fun with the suppressor.

My 300 blk is plenty accurate for practical use, and it's a gasser. Lots of wind and drop sure, but it is accurate. Better than a 178 amax at 2550? No lol, but it is not the same kind of animal.

I would say savage had feeding issues. Lots of rifles with that style of ejection do not like to spit out the short little 300 blk case. Savage and Rem style short action rifles seem to enjoy leaving spent cases in the rifle lol. They would have had to change the ejection style or use a shorter action I think.

Savage prefits for 300 blk are easy to get, but it is just a huge pain in the butt to get good ejection instead of just dropping the brass. I would bet it's cancellation may have had something to do with that. Controlled round feed like on a ruger though, that is the way to do it.

Subsonic 308s work pretty well, great for the investment though. If you have a 308 and a can, sure run the subs. No reason to buy a blackout REALLY. Accuracy is variable though, and consistency will pretty much always be better in the blackout or whisper.

I have one rifle that will shoot around an inch at 100 very consistently with 150 fn sierras and Trailboss. Great load for that rifle. Other rifles can be a bit pickier about it. Just have to be patient and be realistic about what you are after. CONSISTENT 1.5 to 2.0 minute performance is a reasonable goal here. Anything better is just a bonus.

Lots of testing is necessary. Trailboss is the go to powder; find as consistent a charge as possible, then move to OAL tests. They make a huge difference here.

BTW I have done lots of subs in an fcp 10. 10 twist barrel, really liked the 180 sierra RN. Never got to be as consistent as I would like, but it wound up doing 1.5 inches at 100 most of the time.

farmer, if you can do that well with the blackout, why did savage can their rifle due to accuracy issues?
Savage was trying to use a 1-10" twist from what I understand which will only stabilize up to the 220 gr bullets. A lot of ammo out there are 240 gr pills that require a much faster twist.

[farmerboy78]

I have another post about 308 subsonic loads on here. I just finished working up some subsonic loads for the .308 and traiboss is the go to powder for sure. It is pretty quiet itself.

At subsonic velocity, a 1:8 is usually used to make sure even the 220gn are stable. Savage attempted to address the ejection issue with their .300 BLK but I'm not sure how successful they were. It has been a known problem for years with the Savage design which has really frustrated a lot of guys that would like a .221 Fireball Savage.

It's nice to have a standardized round, but in a bolt gun where you don't have to worry about gas volume and pressure or usually magazine length, a subsonic .308 is a more logical choice. With a Savage, getting a 1:8 barrel is a fairly simple matter and you can install it yourself.
