CMMG 10mm Banshee Review

[@BigTimberLodge]

02:02 great point about the ambi-safety. A lot of people don't realize that about a true 90-degree ambi-safety.

[@AlaskanBallistics]

Yep!

[@RanchTop]

Man! I've been low-key wanting one of those for a while. Great video!

[@AlaskanBallistics]

Thanks! Check your twist rate for the ammo you're using

[@kimisdaman]

CMMG strongly recommends Winchester White Box ammo, and I suspect the Banshee is tuned for that specific round. I've tried everything from 180s @ 1000fps, to 220s @ over 1100fps, and the gun really prefers rounds in the middle of the 10mm ballistic road. Radial delay does NOT hold the bolt closed longer than blowback, it is not a sort-of locked breech. I tried heavier buffers, recommended for full-power 10mm, sent the gun back twice, I'm on my third bolt, and just decided to stop trying to make it into something it's not- a thumping 10mm carbine -and load what it likes, rather than get it to like what I prefer. It shoots 180s a little more accurately than heavier bullets, two inches at fifty yards with no magnification. Shoot 180s@1150, or 200s@1100, and the gun will be happy.

[@AlaskanBallistics]

Thank you kindly for sharing your experience.

[@johnw4999]

Check your casings! Especially the underwood 165s! When I bought mine, I immediately put the 8oz buffer in it per instruction manual. Shoots Blazer Brass and Magtech 180s just fine. Zeroed my red dot with Underwood’s 165 Gold Dots and discovered cracked, split and bulged cases! I believe for these awesome 10mm loads, the firearm needs a roller delayed system. No ammo issues from my XTEN and XTEN Comp.

[@AlaskanBallistics]

Didn't happen except once with fiocchi

[@AlaskanBallistics]

I'll show in a short

[@johnw4999]

⁠@@AlaskanBallisticsInteresting you didn’t have any split, cracked and bulged cases, except with one Fiocchi. What buffer weight are you running?

[@johnw4999]

@@AlaskanBallisticsThanks! Looking forward to seeing it.

[@AlaskanBallistics]

@johnw4999 whatever buffer came with it

[@spokanesurvivaltrainingand5797]

I have a bunch of SGM magazines. They use good quality everything and they are made in South Korea in a state of the art manufaturing plant.they use incredibly strong polymer and super tough spring steel

[@brendanm.1399]

Totally agree. I was a little suspect at first but my MK10 came with one. Functions flawlessly so I bought 4 more. BTW I don't have any accuracy issues with mine with a variety of ammo.

[@AlaskanBallistics]

@brendanm.1399 nice!

[@Sackmatters]

Very nice. I’ve got mine setup with a Romeo 5 and a pelican light. My 45 sgm mags work very good. Mine was to tight from the factory. Jammed the first 20 mags and finally ran smooth. Great little pistols just expensive.

[@AlaskanBallistics]

Cool. Glad you had a great experience!

[@GeographyCzar]

200 grain hardcast Underwood vs Buffalo Bore please! (Aww, nuts, I should’ve watched before commenting, you did do the Underwood hardcast. Cool! Too bad it’s all over the board.)

[@AlaskanBallistics]

Yeah. I was really dissapointed with that

[@cw2a]

Good stuff Chuck! ❤

[@AlaskanBallistics]

Thanks bro

[@lysergicaciddiethylamide6127]

I had a 2019 CMMG 9 banshee. I sold it to buy a Robinson XCR. I’m here because I might buy the 10mm now.

[@AlaskanBallistics]

Cool. I like the 10mm banshee.

[@brianleverich4467]

Looking forward to seeing more on this one

[@AlaskanBallistics]

It'll only be a few videos, but should be able to make some content

[@petebrasco]

It’s hard to complain about accuracy when you don’t have a brace/stock on it. I got a Geisselle single stage trigger and a primary arms 1x prism and I am stacking shots.

[@AlaskanBallistics]

Thanks for your opinion. I've gotten it to stack shots as you say... just ammo picky

[@treyveston7965]

Man, sad to see the accuracy get worse as the bullet grain increases! I carry an XDM Elite OSP 10mm as my woods gun loaded with my custom reloads using either 180gr XTPs or 200gr Gold Dots. My current woods carbine is a Henry Black rifle in .45 Colt and I was hoping to replace it with a 10mm carbine. The CMMG Banshee seemed like the ideal companion. But, since the XDM will do 3/4" 5-shot groups at 25yds, then a carbine better be doing around an inch at 50yds. I go where there are wolves, black bears, cougars, and the occasional grizzly. 180gr is the minimum. If the Banshee can't group with 180gr or 200gr bullets, then it is a no-go for me. Nice video, though!

[@AlaskanBallistics]

Several comments indicate that theirs grouped with 180gr... Also the 140gr xtreme penetrator has out penetrated 200gr hardcast in my tests. Don't shy on an all copper bullet just because they are lighter.

[@YellowHammer26]

👍👍 appreciate the review Chuck. Hope you’re doing well.

[@AlaskanBallistics]

Doing good thanks!

[@MattWaller04]

Amazing seeing how wildly this varies in groupings with different ammo... 35 MOA gun to 4 MOA

[@AlaskanBallistics]

Yeah I've got a really tight group in the second video as well

[@MattWaller04]

@@AlaskanBallistics kinda wish it liked the 200gr hard casts though. Cool setup none the less

[@AlaskanBallistics]

@MattWaller04 me too... but it likes my harder 180gr handloads.

[@robertgrimm986]

That gun was jumping a lot w/the bipod and the heavier loads. I would guess a 2 handed hold would have made those groups tighter.

[@AlaskanBallistics]

@robertgrimm986 jumping occurs after the bullet has long left the barrel. A bipod and a rear bag is best

[@MSHunts]

My 9mm does the same thing (failure to hold open on last round) fairly often with new Glock mags.

[@AlaskanBallistics]

Interesting... glock 33rd mags?

[@SPIN1963_]

Bought one of the early models and I found that "if" you suppress it and set it up accordingly the Banshee works much better. Just my experienced though. BTW: Running S&B 10mm 180grn with eleven grains of who knows what powder.I also built a 45 ACP Banshee from parts and I find I get great performance with it (built the proper way) running 230 ball with Unique.

@@AlaskanBallistics that new ruger LC45 would make an awsome 10mm

[@Disastrous.Affect]

I have the Ruger PC Charger and without a brace it is awkward to shoot. The only way I could reliably stay on target was with a single point sling to hold tension. If they don't over turn the pistol brace ban I will probably just SBR it and get a suppressor as well at that point, might as well.🤷‍♂

[@AlaskanBallistics]

Yeah... I've got a good cheek weld on the tube with that bipod. I've had less steady experiences with other guns

[@martinhorst1858]

Great stuff as always!!! I believe if I was going to run a pistol caliber that would be the one. Seems very capable. Look forward to further testing.

[@AlaskanBallistics]

Thanks. Too bad the heavier hardcast didn't perform well

[@martinhorst1858]

Roger that. I was a bit surprised by that. Believe you are 100% over the target with the barrel twist analysis. Lots of questions. I can only assume more folks are using it for 2 legged defense than 4. Would explain the good accuracy with lighter loads and horrific groups with the heavy boys.

[@DropItLikeItsScott]

Noice! CMMG make some great pew pews. I've shot a few and would love to own one.

[@AlaskanBallistics]

They're great for sure

[@NAH1907]

Awesome

[@AlaskanBallistics]

Thank You!

[@alaskagundad7140]

Not grouping the 200 grain bullets is a heart breaker. Maybe when/if they offer a barrel with a faster twist for heavier loads they will re engineer and optimize the angle of the locking lugs and adjust the buffer/carrier weight making the “10mm heavy” model a well rounded woods gun. We can only hope they see it as a project worth taking on.

[@AlaskanBallistics]

It might do better with my handloads, we'll see

[@jw-sigp2258]

Nice gun and nice video. I could see myself using extreme penetrator for bear defense in that. It would be good with 155 grain xtp for home defense too.

[@AlaskanBallistics]

You're a good shot then! Godspeed and good hunting

[@BrassManX]

If it can’t handle the hard cast stuff, there’s no point in spending $1400-$1500 on it. I’ve seen a 12.5 inch version of this pcc online, I wonder if a longer barrel would help?

[@AlaskanBallistics]

Harder lead helps. If you'll see my part 2 you'll see me shooting my 180gr hardcast loads from ckbcastbullets. They're significantly harder than the softer ammo from buffalo bore and Underwood

[@scottbailey8158]

Wow I have no idea what your doing, my banshee shoots same hole accuracy at 50 yards. It likes the 180 grain the best but damn it's still a sweet shooter with 115 gainers too Oh I installed a timney trigger too ya might try to do the 1 lb pull or less.

[@meanman6992]

I have to wonder, if he held onto the bipod and loaded it up, if that would have affected the group dispersion?

[@AlaskanBallistics]

No holding onto the bipod only makes the bipod less steady. I was placing the sandbag under the grip.

[@crsquirrely73]

I had better accuracy then you did with 180 grainsat 50 yards I had less than 2 inch groups. Im wondering if your accuracy was off because you didnt have the brace

[@Macreadysshack]

Isn’t radial delay supposed to soften recoil? I can shoot my G29 flatter than that thing. A shoulder contact point would obviously help but is anybody else surprised by the CMMG’s recoil with watered down 10mm?

Linear comps increase recoil if anything. Whether they flatten muzzle rise or not is up for debate. They are good for shooting next to others outside.
