Who here is running one? I'm specifically interested in "realworld" accuracy and velocity comparisons between it and the 243 AI with 105 VLD's.......As always, pictures and field experiences are welcomed!



X-VERMINATOR

I had one for a short while but never ran VLD type stuff through it. Spent little time working with it actually. You'd likely want a 3.1"-ish mag box if planning on running the really long-nosed stuff. If working with 2.8" mag confines, it is going to be stupid-tight.

Ya, 10-4....I had one built several years ago but it was a pig and a 12 twist to boot...Still got a ton of fireformed brass which has got me thinking!



X-VERMINATOR

xverm,

I dunno' if it means anything to you and you probably have a hold on it already, but Dan Dowling told me personally that he'd never build a 6 A.I. on a SA 700. Maybe it'd work out decent with a Wyatt's box, but I think you're going to really hate sticking those VLDs way down in the case to fit in a 2.8" box.

Boxer has some pretty good pictures illustrating just how poorly it fits into a 700 SA.

Not a 6Rem AI but,, the 6XC COAL 2.740-2.750 fits about everything. Anyway it was designed to fit and feed in everything.

2.750" COAL pictured

USP: Those are some wicked looking little rounds man! That Hybrid sure has a cool profile

Ya, the mag box thing doesn't scare me but I do think a Wyatt would be worthwhile.........Be interesting to compare velocities between the 6mmAI and 243AI with 105's @ 2.8".......Throats are easy.......! On the other hand Lapua brass is worth building around. It's just that I have 1000 pieces of 6mm AI already prepped and fireformed..


X-VERMINATOR

The 6XC is definitely cool but if not for the already fireformed 6mm AI stuff I'd probably just go 243AI for the extra speed and Lapua brass.......


X-VERMINATOR

My 6mm Crusader is close to a 6mm AI. it has a 32 degree shoulder and is same parent case.

accuracy is second to none...



105 amaxes at 3350 fps here in WY. Gain twist Bartlein barrel. starts 1-9 and ends 1-8. great barrels

I run badger M5 with the front plate in mag removed. loaded with the 105 is 2.945" COAL


had a 243AI and it would shoot the 105 at 3274 with great results. and 115 Dtacs at 3178. ran a M5 in it too.

X-verm-this is just my take but add 100 fps for the 6 case over the 243 whether going standard and or Ai'd.

I've been around the 6's enough to know that for me, and emphasis is for me but I'd go 243 AI in a shorty action and 6/06Ai in a long action.

Just my way, best of luck to ya.

No use for a 6Rem unless you've got a box of at least 3".

I'd like to see someone do up a 6AI in a Tikka T3, with things opened up a bit for it to really run lengthwise. That'd be a pretty cooking setup, but of course they only twisted the barrel 10".

X-VERMINATOR I dont get your reasoning at all, you think the 243AI has extra speed over the 6mmAI ????????......wrong the 6mmAI will get you at least 100fps more with 105's. the Lapua brass is a plus though.

I own or have owned several 6-284's ,6mmAI's and 243AI's all with 1-8" twist barrel's from different manufacturers, all 3 have their positives and negatives. the 6-284 is the fastest of the 3 but by far has the shortest barrel life.
The 243AI you can use Lapua brass as you can with the 6-284 but in my rifles was consistently the least accurate and slowest of the 3.
The 6mmAI while not the fastest or slowest had the best barrel life (I am guessing because of the long neck) awesome accuracy, the downside is you have a single shot as I do or use a long action for a repeater and you are stuck with Remington brass.

Having had all 3 if I had to choose again I would take the 6mmAI 8 times out of ten and a 6BR AI for the other 2.

Back up & re-group buddy........I can see where I confused folks..Someone offered up the 6XC which is definitely cool but not as fast as the 243 AI with more forming. That said, I already have 1000+ prepped and formed 6mm-AI brass. If I did not already have these I would probably just go 243 AI over the 6XC or 6mm. The Lapua .243 brass is reason enough to overlook the 6mmm but I built the 6mm long before Lapua .243 brass existed, hence the extra thunk and purpose of this thread!!!


X-VERMINATOR

Thanks "sendero man", that's solid info.........I'm really leaning here!


X-VERMINATOR

I really appreciate you're opinion but keep in mind, I nearly always stray...........

What type of speed range does a 6mmAI provide in say a 26" pipe with 90g or 95g pills?

I talked to a guy that had one with a freaking cane pole of a bbl(29" IIRC) and claimed he was getting speeds far greater than my 6-06 produced with a 26" 9tw Kreiger. I also load for 6Rem and truthfully it's not far behind the 06 for me. Curious how the AI version compares.

Thanks,

loder

What does 6mmAI mean ?


Had to do it !

6mm Remington Ackley Improved .....

I built a 244 Imp using a Weatherby Vanguard (Howa) short action.
I used the info in the "Sporting Firearms, A Designer's Notebook, which has drawings with dimensions on increasing the length of the action to 3.0 inches. It worked fine. My actual velocity gain was about 120 fps over the standard 6mm Rem. Accuracy was the same as the rifle was when it was new and was chambered for the .243 Win.

had some Pm's asking about performance on game...

here is son taking speed goat. turn up the volume !

Great "group"....I mean, HOLE!

This is just me but I've always kind of looked at questions like this in terms of what should it provide for speed. Often times we get the old I can get this with mine routine...Point being, often times people have a tendency to make their round go where they want it go.

I agree for the most part, but there's always a general ballgame figure as well. IE I get 2950 from 150NPTs in my 22" 30-06 pipe, pretty standard for the cart and bbl length. My 6-06 with 26" pipe produces 3500ish with various 90g pills and powders, 3400ish with 95s and 3600ish with 85-87s. What's typical with the 6RemAI in a 26" pipe? Ran loads in a 22" vanilla 6Rem last year that was only a couple hundred fps behind my 6-06. If you consider bbl length and AIing, that certainly closes the gap considerably. Then again, there's always the slow/fast bbl thing and that pesky rule about "no replacement for displacement..."

Thought I was trying to give you some valueable info........if this is your attitude [bleep] you, sorry I tried to help.

Always thought the 6AI was the best of the maximum cased 6mms as far as the velocity and barrel life balance goes.

If you want fancy brass there is the 6.5x57 mm and 7x57 brass from RWS, Norma and sometimes Lapua. All good options if your turning case necks anyway.

Build it.

Please! Not another "dog chasing his tail" thread!

...or should I say, "dog chasing tail" thread?

I did an article on the 6Ackley in Varmint Hunter Magazine - October 1993 Issue. It was on a 1-8" twist barrel.

The OP might want to look it up. I spent a lot of time shooting and working up the load data (not dry-labbed ). The data is good stuff.

God Bless,

Steve

Here's your data, linked from another webpage:

6mmAI data

I used your 7828 info to get a load for my 6mmAI with 100gr Hornady BT's and had no problems killing little forest creatures.

Thanks for the link JPro and the reminder Dogzapper. I had forgotten where I got that from originally. I made my 6mm AI off a Rem 700 LA and a rechambered factory Rem 700 take off in .243 Win. Have both the .243AI and the 6mmAI with 24" barrels and get around 100+ fps more with the 6mm with same bullets.

Thanks for the link to Steve's data JP!

That's really close to the ballistics of a 6-06. Very well may be my cart of choice when I toast this 6-06 bbl. Trying to milk it, damn thing is scary accurate.

Sendero- What powder and load were you running in the 243AI?
