Deer, Hogs, Coyotes, Corsican Rams
Up to 80 yards
14" with pinned muzzle brake to make 16"
Don't remember. It's a Noveske 16" barrel.
Subs were Hornady 190gr. Supers were Hog Hammer and Winchester Deer Season

Only pigs
30-100 yards
9"
1 in 7
A few different 110gr supers. My fave is Nosler Varmageddon

Behind the ear drops them in their tracks.

Bender. This is a subsonic application…. I built up a .300 blk using a 700 Rem action and a 18" SS Hart barrel with 1:7 twist threaded for suppressor use.
My need was a rifle to kill hogs but also to use for culling numbers of WT does and exotics like Fallow and Blackbuck fairly quietly on the ranch for numbers management.
I handload using Hornady brass.
7.8 grains Hodgdon "Lil Gun" powder
Sierra #2165 200 gr. Spitzer Boat Tail
CCI #400 Small Rifle Primers
COAL - 2.270"
Velocity- Subsonic @ 50 degrees and 2100' altitude. (Approx. 975 fps)
For the animals above I try not to shoot over 75+ yards with the above load suppressed for consistent quick kills.
Have had good kills with it though.
I've never loaded up or used it for supersonic loads so can't give any data.

Whitetail deer x2
60 yards
10.5 inch suppressed
1:8
Winchester Deer Season XP

What game did you hunt? Axis, Whitetail, Hogs
What distance did you take the shot? 40-187 yards
What barrel length? 8 and 8.5 inch
What twist rate? 1:5 (hits harder with subsonic) stabilizes the bullets with the faster twist rate.
What ammo? 2008-220 grain subsonic various manufacturers

I've taken hogs and deer with no issues. Some super with Barnes 110 and subs with good expanders. I don't use Hornady sub-x at all. Had terrible results with them. I have 7 to 9in setups some with 1/7 twist and a super short with 1/5. Shots have been up to 130 yards with supers and under 100 with subs.

Deer and hogs from 50-100yds
120gr green box OTM when they were still available
120gr Barnes bucket OTM since then
10" Rainer ultra match 1:7.5
They don't go far

I have an 8" mini fix only ever been sighted in with 220 gr subs and I would trust it to take white tail or smaller out to 100 yards. If I was to ever switch to just supers I feel like it could be very easily capable out past 200 yards with no issues (could be wrong) on white tail or smaller.

I just bought a mini fix in 6mm arc, and bought the 300bo and 224 barrels for it.

Have you shot it with the 6arc set up yet? Was really thinking about getting that set up for mine

Not yet. Hope to get it out on Tuesday. How do you like yours?

Had it for probably 6 months and when at the lease it's the gun I grab the most to ride around with. Super light weight and extremely accurate even with heavy subs.

White tail deer
115 yards
20" (i think, it wasnt my gun)
No idea on twist rate
115 supers, not sure of the ammo brand

It did its job.

Out of a blind 85 yard WT doe 110gr Barnes suppressed 9" 1:7 double lunged, it ran in a few circles then plopped over.

Spoil island drive 150 yards or so WT doe. Hit it back some. Might've emptied a 20rd mag on it as it ran off - it ran into a pond as I kept shooting and I'm pretty sure it eventually drowned

Same hunt diff year a spike walked out 10 yards in front of me and I hit it low as it was quartering towards me (not knowing my hold over) it ran 10 yards , stopped then I shot it in the neck and it dropped.

AggieRoofer and TXJD, part of the reason I asked this question is one of my big projects this year is changing up my 300blk Minifix from a lightweight subs focused 100y and in option to something more flexible.

I have a 12.5" Noveske barrel for it and a Steiner 2-12 that will be getting installed soon, and then I'm going to try and stretch its legs with both hot 120gr supers and subsonics and see how far out I can make reliable hits with both...on paper and steel for now, but maybe hogs once I've really wrung it out and know what it can do.

@Bender these companies make additional barrels (calibers) for the Fix and Mini Fix if interested. I went with the 6mm arc version of the Mini Fix and ordered a 223/556 bolt and barrel from TAG so that eventually I can have 300BO, 6mm ARC, 22/556, 338 ARC and 22 Nosler barrels.

What is the barrel twist on the Noveske?

Its 1/5 like the factory barrel.

would not recommend unless its hogs and does......and inside 50 yards and you are 100% sure you are going to hit where you are aiming. know of 2 folks that have got rid of theirs.

You taking about mini-fix from Q or just 300bo in general?

I bought 300bo with a can for hogs and yotes because it's as quiet as you can get- to be courteous to neighbors as well as protect my own hearing, with subsonic ammo leaving the possibility for more effective follow up shots. But alas, I'm a novice, don't know wtf I'm doing and haven't shot a single hog or coyote yet.

I like the idea of harvesting one whitetail per year off my property to stock the freezer out there, but not ready to do so yet- yes- would be within 100yds, considering using a different ammo than sub-x for the 300bo (zeroed at 50yds and confident in accuracy from a rest with the subs), buying a different caliber upper for the ar-15, or just buying a whole new setup on a different platform (ar-10 or bolt action) in 308 or 6.5cm.

the hornady sub-x seems to be the most commonly available, and often only available, subs at the big box stores like academy. what is the problem with them?

i will say that I had the damnest time getting all brands of the heavier gr subs to properly cycle when I first got my 300bo rifle. took it back to the LGS a few times thinking the gas block or buffer or something needed adjustments as heavy subs + a can was causing cycling issues. ...turns out it was a feeding issue- switched out standard 556/223 mags for magpul mags made specifically for 300bo and it feeds and cycles fine with all 300bo types and grains I've tried now, including the heavier sub rounds.

just in general. they definitely loved the quietness of it but the fear of losing deer caused them to go in other directions.

in my opinion you should never sell a gun and they should have just kept them and used them for hogs and yotes like you mentioned.

I quickly abandoned the use of subs in my 300 blk for hog hunting because of the ballistics. A 220 gr sub will drop almost a foot at 100 yards, maybe more in 7-9" barrels (not sure).

I say this just because you mentioned follow on shots…1) it is a myth (IMO) that hogs won't run using subs because they're so quiet. They still cycle the action of a AR which is well over 100 dba and when you hit a hog it sounds like a baseball bat hitting a watermelon. I've found this to be true even with bolt guns too, minus the action cycling…remaining pigs know something is up. 2) When shooting hogs in groups at close range, they will run fast after the first shot and if you want to shoot a few out of a group, you'll have to lead, often quartering away. Accounting for the lead is hard enough without accounting for bullet drop too.

So, for me, that's why I like 110 gr supers. If you intend to walk around with a lightweight SBR/pistol with a short barrel, 110 gr supers out of a 300 blk have more energy than 556 at similar barrel lengths. Sure there are many better rounds for that first shot, but lugging around an AR10 is tough, then I need sticks, etc.

Just some food for thought for any and all, not just you

Where I have found on our ranch to be of most benefit using the .300bo was using a bolt gun with suppressor and sub ammo, ….. when you had a sow show up with a a bunch of her piglets.
If care is taken in proper shot placement of the sow…she will drop without squealing and the piglets will stay around her. You can then oftentimes kill many of the piglets before they start running off….and even then they oftentimes return to mama if they have not had a loud report to scare them.
With a little luck I've been able to really do a number to a pig family with it. No sound from a slamming action of an AR really helps accomplish such.

Thanks. that makes sense.

The OP is using a bolt action

Yeah, thanks. Sorry if I derailed. I saw his second post, so that's why I added my note about bolt guns for hog hunting, which he mentioned as a potential use. Just throwing out what little useful info I possess on the topic for him or otherwise.

I hadn't heard of a Mini-Fix prior to this thread. I personally don't have much utility for a short-barreled bolt gun in 300 blk, especially at that price point, but it looks like a cool platform. If you could only make one short shot, like a heavy wooded area, maybe the 300 blk subs from a bolt guns make sense. I think I'd still want a longer barrel for that or paper targets though.

Thanks for all the replies so far.

I don't know how many of yall remember but I built a 12" 6.5 Grendel AR a while ago as an attempt at a "do it all" kind of gun....something capable of either self defense or hunting at say, 400 yards and in.

I still like that gun a lot, but started reading the online ramblings of someone who's even more of a gun autist than I am, who had the same general idea but wanted to do it with a ~12" barrel from a minifix.

One of his points of comparison was a 120gr hot loading of 300blk out of a 12" barrel being similar to a 120gr 6.5 grendel load from a 12" barrel....but with the ability to run subsonics too. He has written about hunting fallow deer at almost 400y with supers, pigs with subsonics out to 270y and a cow elk at 120y with subs.

And that idea certainly grabbed my attention.

I'll start a thread eventually on the whole project, but with this thread I mostly wanted to get an idea of what kind of distances people were hunting at, what barrel lengths, etc so thanks to all who have responded.

I also have some free subscriptions to the substack of the guy who developed the project if anyone wants to drop me their email and read his ramblings themselves. He has some interesting ideas.

I've recently been looking at the 8.6 blackout for a similar role.

Bender (or anyone else) have you tried any of the cartridges that are NAS? They have some 556 or 30 cal (need to rewatch it) going 3500+ fps, and have a 300 blackout option for 110 supers

I am also thinking about getting a 8.5" blackout bolt pistol and think these could be better options for that. Only a few though, the PSI is almost double which makes me hesitant..

ETA: here is where I first saw it



ETA: dang ADHD brain

Thanks sir!

I've got an 8.6 gas gun. Haven't got to do too much testing with it due to ammo being hard to find. But hopefully soon I can get all set up to start reloading my own to do more testing.

I have, actually. During the 300 Blackout drywall tests , one of the tested loads was a 200gr projectile loaded in a NAS3 case from Phantom Defense. We also tested a 205gr load from Sig and a 190gr load from Hornady.

The Phantom Defense load in the Nas3 case had higher velocity from the 5.5" barrel than either of the other loads did from the 9" barrel.

200gr Phantom NAS3: 1012fps from 5.5" barrel
205gr Sig: 978fps from 9" barrel
190gr Hornady: 1005fps from 9" barrel.

That's a big part of why when I was reading this guys substack article about pushing a 120gr 300blk projectile from a Nas3 case and a 12.5" barrel as a possible equal or better to 6.5 Grendel or any other ammo type from a small frame AR I didn't immediately snort and roll my eyes.

I have a small stash of Phantom's 120gr Tac-Tx loaded in nas3 cases to test out. I need to get some velocity and accuracy data from the stock 8" barrel (hopefully this week or next), then I'll swap over to the new 12.5" barrel and get some comparative data.
