5.56x45mm (NATO), 55gr FMJ, M193, GGG 

Most definitely. I think running the 2 in tandem is a good idea though?

@@BuffRANGE 100% Going to be interesting when you figure out which is more accurate. The higher number or lower. Fingers crossed it’s the higher reading one. 😝

Go with a magnetospeed. Those will give you accurate numbers.

should be more like, "no 2 chronographs agree with each other"

Are they both radar based chronographs? If so they could be causing interference with each other. I know running multiple radar detectors in a vehicle is often considered a bad idea because they cause interference. I don’t know though I’m just curious.

It has some administrative shortcomings vs what I've been doing easily with the standard chrono, but it's not much of a learning curve, and the setup is a breeze for actual use :D

You bet!

Good to know!

not wierd, just alittle unrealistic. i mean, anyone would want more velocity out given barrel length. but that seems pretty hot.

@@mtnbound2764 Okay. +\- 50fps 😏… 2700 out 10.5 the minimum though. Winchester m193 usually does that.

That's not unrealistic at all, with tac the top load is 3450

Actually it is considered good quality in Finland. It is usually better accuracy than most other bulk ammunition. Currently too expensive here. Probably because it is now sold to US instead.

​@@jpenna1976 Alot ammo goes to Ukrainie currently. ALOT.

@@michamichaowski8375 True. For about 1.5 years all GGG production went to NATO countries who suddenly realized they actually don't have that much ammo after all...

@@michamichaowski8375 Not got discount on 5.56 GGG. 0.60€/piece, but I got to order 3600 rounds. Well, that will be for next couple years. For refenrce, cheapest .223 is Geco and discount price is 0.55€ when in 1000 box.

Long and Strong :)

You know that is another viable option as well. When I did work with Aimed Research he told me you can count the frames the bullet travels, and with simple math have velocity...

@@BuffRANGE I think you’re going to need to do that to be definitive

@@BuffRANGE just make sure you do the math right lol

@@BuffRANGE make sure you measure the same exact bullets with all of the chronographs all at once , garmin, optical and high speed camera all together bullet by bullet

@@davidjernigan8161 1/9 will stabilize 77gr bullets. Might be on the edge, but they don’t tumble.

In my experience 1/9" twist will stabilize 77gr pills but shoots a bigger group than a 1/7" twist.​@@TooManyChoices1

For that money you could get a CZ 600 with out of the box 1/7" twist 5.56x45

Yeah, that chronograph sucked

Maybe we consider the Light Screen variant as "realistic" and the Garmin as "optimistic". I think going forward it may be good to include both data sets. Sometimes the Garmin is +30, over +100, and other times very close. I'm not sure there's been any indepth studies to definitively say the doppler radar are the most accurate?

In theory, the dopler radar should be significantly more accurate than the old optical chrono's.

@@BuffRANGE I’m using a garmin xero too. From what I’ve read and AI tells me they’re supposed to be super accurate. The old chronographs rely on light , etc so more variables to go wrong? More research is needed like you said

@@BuffRANGE I just did some more research and from everything I’ve seen the garmin should be most accurate. It’s on par with Labradar. Optical chrono’s they have to be perfectly aligned as well as specific lighting. It’s possible you weren’t always lining it up perfect too

IMO depending on your use case, if current production LC/WIN M193 is sealed on both ends, that is my long term go to for spec M193. Then IMI as there are some reports that recent lots aren't sealed. If you're just shooting, get whatever has the best price :D

GGG 223 Rem is basically M193 velocities, they're labeled as 223 Rem because 223 Rem is a sporting cartridge while 5.56 NATO isn't in the EU mind the lot that I have was almost breaching 3k fps from a 13.7" and 14.25" barrel respectively, though YMMV. Save yourself a couple pennies per box.

@@BuffRANGE Thanks for the reply, but I thought Winchester M193 (LC ammo) does not have primer nor bullet sealed? Unless i missed within one of your test vid. Any how if anything I guess for long term stockpile I would stick with PPU (Prvi Partizan) decent velocity and good accuracy for factory ball ammo.

@@uhavedied12334557 there are several videos I saw that GGG .223 never reached close to Buffman GGG M193 velocity, yes I do understand the lot variation, air ambient temp and difference chrono reading. Other EU/Nato ammunition import here under 5.56 Nato such as Norma, Ruag, Sellier and Bellot, GGG and MFS Defense. Then there non Nato countries ammo such as ATS, Sadu, Igman, Prvi Partizan who also under the 5.56 spec and/or .223 Rem spec. In my experience without chrono read out the hottest .223 Rem load is from Lake City (.223 Rem Winchester white box/ Herter's .223 rem). most .223 Rem has hard time cycle reliably in Zastava M90 with gas setting 2. Only .223 Rem from LC ran perfectly fine. For plink or tuning adjustable gas piston/block i use PMC bronze to bench mark for cycle reliably. For normal range plinking/ practice I use PMC X-Tac or whatever reasonable at time (I still have quite a bit of Winchester LC M193) To my understanding Lake City stopped sealed their commercial rounds around 2019. Claiming they save about $20 per 1000 rounds, this when Federal still under contract to operate Lake City plant. Now for long term storage I want M193 has sealed neck and primer like my old IMI, PPU.

@@BuffRANGE GGG seals both ends of their ammo. They have been doing so ever since 2015 if I remember correctly as this is when they begin stamping to nato specs which require both sides of ammo to be sealed.

The 70gr TSX ? Getting some from AAC

Likely due to the more mass produced nature of this ammo

the jacket itself does not attract a magnet on the lot I have.

This lot I have does NOT attract a magnet..

According to the manufacturer's rather in-depth data sheet for their M193, it is a copper jacket with a 2.2% antimony lead core. I don't see any bimetal jackets on their 223 ammo. They also recommend it is shot from 1/9" or slower twist barrels.

Appreciate you checking for me. I seen some people say in some reviews that it had steel jackets.

more so the M85 has become a collectors piece :)

@@BuffRANGE Yeah they cool, but heavy and awkward like an MP5 😂

It's currently not a constant fps or even a %. I had one the other day on one shot the light screen was faster :D

@@justinassobieskis did I say it right ?

@@BuffRANGE yep

lol, maybe add 5.56 or M193 to GGG

That's a good thing and bad thing. I'll take the weight hit for less felt recoil, but in the grand scheme of things with a brake and or can, recoil on .308 is nothing a 9 yr can't handle :D Carrying around more weight though is sometimes not good.

The latest AI models told me it’s believes 50% likelihood that JFK was killed by the government/CIA . 50% is high as crap. Coin toss

Who alleges that, exactly?

You're really reaching here

Could be younger brother 22-250 remington too, wildcat at the time. There's no definite proof as we know

@@Almost_Made_It First time I see such theory.
