Well, decided instead of getting another .300AAC.Bo,
I'd step up to the .458SOCOM...does supersonic & subsonic only BIGGER & badder:D
Wilson SOCOM Project, for me ! With a second Wilson Sniper upper in .223Wylde.

Anyone shooting the .458 SOCOM, how do you like it, and what do you use it for?
 
For me it was only a hand loader's proposition at about $3-4 per round. Costing maybe $40 to fill a ten round mag gets my attention

Never did a whole lot with mine. Seemed to do OK with 300's, 350's, and 400's. When you start getting on the upper end, recoil gets interesting. Bullets alone cost a minimum of sixty cents. Buy a brass catcher. At over $1 each, too expensive to end up in the grass

Accurate enough for deer hunting but never exceptionally accurate, maybe 2-3" at 100 yards at the best. Mine never liked H-110 which is what most guys use. I think I ended up with AA 1680, but I would have to double check.

Our range is in a woods. It would plow a furrow in the leaves. Hard hitter

I had a chance to get a wild cat based on a WSSM case that has over twice the range, shoots way flatter, is much cheaper to shooter, and far more accurate so I went that route for deer

I have one. It's an SBR AR15 with a 10.5" barrel. I prefer subsonic loads for it and my favorite uses IMR4198 and a 500 grain Hornady RN Interlock bullet. I used a Thompson Machine QMF-CQ .45 suppressor on it this year for deer season. Probably not the best for long range shots, but at 25 yards, it did a number on the buck I shot. Plowed through both shoulders and the vitals like a freight train.

I'm a fan.

Wow, 500 gr.for deer...
...guess no different than a slug for deer...just a tad more pricey, lol.
Sounds like a very cool set-up , though.
 
Mine is a 16", with a 405 JSP at 1600 fps it will shoot an inch and a half at 100 yds with a red dot.

I use subsonic loads more often than not, with a suppressor it makes less noise than my M4 2000 or 762 SD on .223/308.

Then let me ask you...(and anyone else that is knowledgable on this...?),
with the .458 SOCOM, can you shoot subs UN-surpressed, no can?
Is it similar in that regard, as long as you can adjust the gas?

On the .300AAC, with an adjustable GAS-BLOCK ...that is NOT a problem, subs cycle just fine.
IF the gas block is "adjustable". as some builders like JP, PNW and Wilson use...then ALL ammo shoots well.
 
If you pick the right powder for the bullet weight and speed it will cycle just fine.

Oh Ok...do you know a good source that has load data for the .458SOCOM, it being fairly new, don't imagine it is in those Reloading "Bibles"?

You need X amount of gas at Y max pressure to accelerate a bullet to 1,050 fps or thereabouts. This is why .300 AAC BLK subsonic loads are typically around 220gr. If you go much lighter you need less gas to get the bullet to 1,050 fps and then you don't have enough gas to operate the bolt. If you increase the size of the gas port you can get around this problem to some extent. I went the .450 BM route and plan on shooting subsonic loads but with bullet weights in the 250gr to 300gr range there should be plenty of gas to work the action whether suppressed or not without the need for an adjustable gas block.

Spoke to the AR "guru" @ Wilson Combat today ( also, JP & Daniel Defense )...
...Wilson does NOT use an adjustable gas block for their .300AAC and their rifles cycle ALL ammo, unsurpassed flawlessly , sub to super.
In fact, he said he owns one with 16" barrel, ( I like the 14.7' "pinned" ) and no problem with subsonic without a "can".
The problems, he said, lie more with the variances in ammo manufacture and powders used. Some work well, others do not...find the ones that do and you are good to go.
He said they make their guns in such a way they shoot everything.

I believe him...if you ever dealt with Bill Wilson & Wilson Combat, you know what i'm talking about. Class act & company, amazing 1911 pistols and now the AR15 & 10's.

Now their .458SOCOM does use a adjustable block...and beefy buffer spring...but even when not, the power of the .458 seems to cycle reliably without, they do it because it is a great "hand-loaders" round.
It will inspire & motivate me to start reloading & hand-loaders too.

He may be the AR marketing guru but that is simply a false statement. "All ammo" would include anything that someone could put together and that is just not the case.
 
And I would add that his ARs might be over gassed with supersonic loads if they run "all" subsonic ammunition without a suppressor attached.
 
I'm beginning to wonder where the OP is to find ammo when he has his rifle finished?
