I’m wanting to get a 300 Blackout bolt action for strictly suppressor use. How accurate is the Rem 700 SPS 16” 300BO? I just picked up a 700 SS Milspec 223 16” 1-9 twist for a steal. I have heard mixed reviews about it’s accuracy but the first two 5 round groups with different ammo were much less than .5 moa. So how is the Blackout?
 
I played around with a custom R700 with a LW 1:8 twist barrel in 300blk for about a year.
With supersonic loads using 155 grain scenar it was a 0,5-0,75 moa rifle at 100 meters. Accurate out to 450 meters.
With subsonic loads using 220 grain Scenar-l and 208 grain A-max it was around a 1-1.5 moa rifle at 100 meters. Any further pretty much sucked.

It's a fun little cartridge, but don't expect it to be something it was never ment to be, I.E a super accurate long range cartridge.

I’m not looking for 1/4 moa accuracy from a factory 300 Blackout. I’m not trying to shoot subsonic out to 200 yards, I’m just wanting it to be quiet and shoot 1 moa or under. All of my rifles are 1/2 moa.
 
All of my bolt guns are custom and guarantee 1/2-3/8 moa except the Rem 700 SS Milspec I just picked up. Here are the first two 5rnd groups. Federal Premium 73gr Berger and PMC Tac 77gr. I pulled the last shot

I've got an earlier production Remy 700 chambered in .300 Blackout that I SBR'd (short barrel rifle) cutting back to 10". The stock rifle is very particular on loads so I plan to rebarrel it with a premium tube. It shoots 110 supers very well, sub MOA, but it's very picky on the subs and I've found reloading is a must.

Heavy sub sonic bullets need more barrel. My guess is your 10 inches isn’t helping anything LOL
 
I owned an AAC-SC (Rem 700 tactical with allegedly an upgraded barrel) and after a few rounds were fired, heating up the barrel, it would fling shots all over the place.
Point is, Remington 700 barrels can be good or bad, there's no way of telling which you're getting until you shoot the rifle you get.

With less than 10 grains of powder, I am sure that a 10" barrel is plenty long for the caliber, no matter what bullet you choose. Heavy bullets do like a faster twist though. My 300BLK had a 1:8 twist barrel.

I have a AAC-SD in 300BLK and it shoots 1.0 " to 1.25" @ 100yds with 220gr SMK handloads. Tried Rainier 180gr Leadsafe and Gallant 217gr Poly coated, the 220gr SMK are the most accurate bullet I've used for subsonic 300BLK. so far.

Not untrue in my experience.
The only 2 Remington 700s I bought had crap barrels.

I'm split on this one, the SPS Varmint I have is a hammer with everything from 155 scenars and custom comps all the way up to 190smk in a 1-12" twist barrel.
The M700 I have in 270win I haven't been able to get the accuracy I want but havent really pushed it very hard for the higher node were it seems to want to be with 140-150 class bullets.
I think I just want a KRIEGER or Bartlien barrel on it so I haven't pushed any higher ?

I have a 5R in .308 that I would put up against any custom rifle including my own. My father has one as well with a 24" tube and it is just as good of shooter as mine. I only shoot 175 FGMM. I have a .270 win sporter stainless steel with a jeweled bolt. It shoots factory federal fusion 150 grain like match ammo. It does right at 1" or just under with other federal and hornady loads (non premium). Corelokts it doesn't like so much. I have never ran handloads through either of these rifles and probably never will.

I think as long as a man stays away from the lowest cost Remingtons, he has a good chance of a nice shooting rifle. You do give up something when you go cheaper. Still no guarantees I guess.

A Remington SPS Tactical AAC-SD is not a low cost Remington rifle.
Remington AAC-SD
Mine was unusable, after lots of experimentation with FGMM 168 and load development, it would become a 3 plus MOA gun less than 5 rounds into the day. Couldn't hit a full size silhouette at 500 yards.

One guy with a rifle that shoots one hole groups is no more a statement of the general quality of Big Green than is one guy with a rifle that shoots a shotgun pattern. What you get from the internet are anecdotes that are confounded by shooter error, crap ammunition, and poor maintenance. "But, muh rifle..." you say? Yes, it is one rifle, in a sea of hundreds of thousands that we never hear about. All that you can truly say is that you pay your money and get what you get. I've got a 700 mountain rifle chambered in 270 win, bought in the early 90s, that shoots my hand loads sub moa. It shoots most factory loading about 2 moa. For a light weight deer/elk rifle with a very consistent cold bore shot, its all I can ask for. That said, how my rifle shoots has no bearing on how someone else's rifle shoots- or how a new rifle will shoot. Remington rifles are not crap, but they can be a roll of the dice.

A 3 moa rifle should be able to hit a full size sillouette at 500 yards all day long. That feat of non-accomplishment falls back on the shooter. I do understand that a few people end up with bad products from time to time. The vast majority of Remingtons shoot well. A few do not and I get that.

3 MOA was the best I could get it to shoot a 5 shot group at 100 yards.
Beyond 5 shots it was a lost cause, shooting at a silhouette at 500 yard was wasting ammo.

I have no such issues with my AIAX or .223 AI or 6x47 Lapua.

Problem with the AAC-SD was not the shooter, regardless of how much you talk (type) out your ass.

As far as "the vast majority of Remington rifles shooting well", have you gathered data from a sufficient sample size before posting this conclusion, or are you typing out your ass again? I suspect the latter.

Interesting then that with my other rifles (AIAX in .308 or 6.5 CM, 223 AI with Bartlein barrel, 6 x 47 L with K&P barrel), I can shoot sub MOA 5 shot groups out to 700 yards (longest distance at my local club) in the same conditions.

I dont care what other rifles you have. We arent talking about them. What i was merely getting at is that a half ass shot with a 3 moa rifle could hit a full size silhouette at 500 yards most every shot. The story you told doesnt make sense unless one of these two things is the truth: either you cant shoot for shit, or you are making it up. At least one of these two things are true (probably both), or you would have been banging steel that day with your 3 moa remington.

My sample size that I shared my experience with is three times or 300% statistically more relevant than your sample size of one. I have experience with many more that I hadnt talked about. Quit talking out your ass.
 
I consistently shot 3/8” - 1/2” groups with mine using 125 grain Nosler ballistic tips and H110. This was using cut down LC brass. A friend of mine has the same results with his using the same ammo.

The houge stock was the problem with my 700 aac bo.
Too soft to run a bipod, sure felt good and was quite in a stand.
Fix or replace the stock.
Kept the stock and will attempt to fix it but magpull gtg for now.
Hopefully can get the stock fixed and back to original just for grins.

Think rem is now selling this same setup.
 
I haven't even shot supers in it, steel at 200 a couple of times.
It's a dedicated suppressed sub gun, I have plenty of hp guns for work past 100.

I tinker with it for 125yd max accuracy.
I want to try some flat base bullets to see if I can tighten the 1-2 in groups at best.

I'm sure 300 would not be a problem with supers in light weight rounds,
Just not what I use it for.
I probably dont have enough scope on it to shoot the subs past 200 to be truthful.

I know of three 700 AAC-SD 308Win that shoot at most 1-moa out to 600yds with handloaded 168gr AMax. Two (my co-workers) are bone stock with only shimming the front action screw due to forearm fit/flex from the hogue stock. The third is mine and it is in a Manners with a Timney CE trigger.

Now back on topic, AAC-SD in 300BLK was my first choice and second choice was a CZ 527. Chose the Remy because of more upgrade options. I've only shot out to 200m mainly because it is a dedicated subsonic rifle.
