6mm remington ai

[GT Accuracy]

Might want to think about bedding the chassis. I had a few chassis (other big name brands) that were not flush with certain recoil lugs and bedding them brought the group size right down

Also if you do find it's twist, before you settle on a bullet be sure to verify your twist then run the bullet through a twist calculator using your twist and the lowest values you're likely to see for each of: FPS, Temp, Elevation.

Temp and Elevation impact required twist rate for a given bullet at xFPS considerably.

Just mentioning because you said yotes at night so I'm thinking winter. Even if you're at roughly the same elevation if it's 50+ degrees colder you want to assure your load holds up in those colder temps, build in some buffer to that twist rate as besides temp your load may be somewhat slower as well.

I’d stop wasting money and get a new barrel, it is telling you all you need to know. Have you borescoped it?

 

[SeabeeKen]

My 6ai, 8 twist shot average with light bullets but when I switched to Berger 108 elite hunter the group went right to .027" which shocked me

I have a 6mm remington ackley that is giving me headaches. Here are the specs:
Stiller Predator LA
Mcgowen Precision 26" bbl 1:10t
XLR Element 4.0 chassis
Elftman trigger
I've ran almost every bullet/powder combo imaginable. Changed brass, primers and dies. Round count is at 165. This thing will not group to save my life! Any advise??

Yote,
I only have one 6 AI it’s got a 1:14 I built it for a hot rod groundhog rifle, it’s a blue printed Remington Action, Jewel trigger, HS precision stock and a fluted Krieger barrel. It will easily shoot in the 2’s and in the 1’s occasionally if I do my part. I picked an odd ball powder to fire form and it shot so well I never left it. 65 grain V max bullets and imr 3031 powder.
What twist are you running?
Have you looked at your crown?
Have you checked it with bore scope?

I’ve never ran a Mcgowen so know nothing about them but if it was chambered correctly and has a good crown and you have checked all the other obvious things like screws and scope could be the barrel

One last thing just thought of as I was ready to post,…. Make sure your stock screw isn’t hitting your bolt lug

My 6mmAI is a 1-12 twist. It really likes the 55gr Nosler BTs and Sierra 60gr FBHP over N160.

 

[Plumsask]

In my 8 twist, a 90 gr sierra tipped game king and H4831sc pushed it to 3500 fps with low es and SD and very small groups. Furthest coyote with this combo was 656 yards, Many more in the 500 'ish.

I'm also shooting the 108's in my Ai, what powder are you using? I'm using H4831sc and it's produced fantastic groups.

 

[AckleymanII]

In my 26" Douglas 10T, Win brass, Rem 9 1/2. 70g Nosler, Win 760 at 3980 fps shooting sub 3/8", 95g Nosler ballistic tip with R#19 & IMR 4831, at 3550

my 26" Shilen 14T, 70g Nosler at 4100 fps shooting 1/4-3/8", 80g Sierra Blitz bt at 3800 with R#19 using cci 250

 

[drop_point]

Try H4831SC, H4350 and being a 1:10", you probably will be best with 75-90 gr bullets. My old 6mm AI loved 87 gr V-Maxes for varmints.

N-165. Left hodgdon and wont be going back

 

[Liven The Dream]

Had a straight 6 Remington 30" 1-8 shot lights out at 1000 yards.
115 D-tacks at 3015 . H4831 SC CCI BR-2's
1700 Rounds the Throat was Toast .

 

[WV Hitman]

I have a 6mmAI Encore handgun. Shoots 70 gr. BTs & 85 gr. Nos. PTs great over IMR 4831. Done deer, groundhogs, javelina out to 400 yds.

 

[Loudenboomer]

My 6mm AI 1-10 loved 100 gr bullets and 4831 in the upper nodes. This was back before the interwebs. I used 240 Weatherby starting data and worked up from there. YMMV

 

[Webster]

I have a 6.5 cm, 2 6mm cm, 22 cm, 243 ai, etc. I just wanted a laser to make shots at night easier.

If you sight just about any rifle in at 250 yards, You don't have to hold over or under more than 3" out to 300 yards.

 

[Webster]

I've ran a few 6mm Rem. I agree, they are not fussy at all. This is the first AI version I've had. The barrel came to me from McGowan, out of spec. I sent it and my action back and the fixed it. I still think the chamber job was a hack.

I shot a Rem 6mm for 40 years for GH hunting. It's a real barrel burner if you shoot it a lot. a 6BRX is a winner. Accurate, good fps, good barrel life. You don't need to get hung up on the numbers. Are you really planning on shooting extreme distances at night with a thermal scope?

600 is very possible. Farthest kill was at 563.

I usually zero 1.5-2" high at 100 yds. 300 is pretty much point and shoot with my 6cm,22cm and 243 ai. I very seldom let yotes get any closer than 100 yds. It hy trigger finger!
