Home Forums Hunting & Shooting Custom Rifles & Wildcats 6MM Rem AI

Having never fired a "boolit" in my life, I am unsure what might be required to get one to work. I agree with the sentiment that a faster twist is almost always better. With a faster twist, you don't have to shoot longer, heavier bullets but you can. Use a slower twist and that option is gone. The last two 6mm AI's I built had 8" twist barrels. Both rifles handled 105 amd 107 grain bullets just fine but the most accurate bullet in both rifles was the 85 Sierra hpbt. GD

I'd much rather always have a faster twist. As always when I end up with a factory 6mm or 224 cal rifle I'm always disappointed and wanting a faster bbl. Never ever had a problem with lighter bullets in fast twist 224 guns.
My custom 1 in 7" twist standard 223 chambered 700 shoots great groups with 50's and great groups with 75 and 77s of all brands.
In 6mm an 80 or 85 Barnes will hammer deer under 350 at anything I've tried over 3,000 fps if you are stuck w a slow twist. Prob most good 75 and 85 sp bullets as well.
Do with a 6.8 all the time with 85s and same range with 75 amax in the 223. Put it in his heart and lungs and they are dead soon enough. Most will pass through when broadside. Other angles I've only had opposite side skin catch em.
They will open at 350 when launched at over 3,000. Even yotes and 40 lb yearling does are enough to open em up completely and pass through at 300-350 and every range in between.
I have shot a bunch of the 85s barnes and should maybe save money and try a cheaper sp as I know they will work, but on a big 250 lb buck quartering away I would rather KNOW the bullet is gonna get to his boiler room. It will.

9 1/8th should do fine with a 105 A-Max then eh? 243 AI flavor...

Go as fast a twist as you like. But Keith and Cumminscowboy are steering you right.
At up to 350 shoot a good hunting bullet and be happy. You'll have the fast twist to play with the high BC stuff later. Fast twists shoot lighter stuff fine.
You aren't gonna "over stabilize" a NP or a Barnes.

the 9 1/8 will stabilize a 105 AMAX (done that), but not the 115 DTAC (or so I've heard; haven't tried it yet).

I run the 115 gr Berger in a 6mm Rem, with a one in 7 twist..on a REM 700 Long Action...it is flat shooting and the long action allows the bullet to be seated out pretty far..

with a 24 in heavy magnum contour Pac Nor barrel on it and RL 19, it can be pushed to about 3250 fps MV..

an AI may exceed that, but it certainly will duplicate it..

I've competed in some local casual 1000 yd shoots with it and it did real well...at least for me..I wasn't competing with the other guys really... I was competing with myself, to see how much improving I could accomplish...

that combo made it pretty easy..

as Mac Davis Sang:

"Oh Lord its hard to be humble... when you perfect in every way..I can't wait to look in the mirror, because I get better looking each day... to know me is to love, I must be a helluva man... oh Lord its hard to be humble, when you're perfect in every way...."

It is hard to agree with Big Shtick, but he speak's the truth on occasion!!!!!!!!

Seafire,
A few things you left out.....is your Pac-Nor a 3 groove ??? were the 115gr Bergers target or hunting ??? were you really using RL19 or Bluedot ??? how many rounds down the barrel ???

Try it so you can see what a keyhole look's like.

Beyond the twist rate; I had a 6 Souper Pooper which is about the same volume as the AI and I remember spending more time scrubbing RL 22 out of the throat than I did shooting it. I rechambered to something smaller and was much happier.

No Blue Dot, not a 3 grove, yes using it for target so far with 115s... use 75 grain HP Hornadys for varminting... why do you think I use Blue Dot in everything all the time??... rifle has about 1800 or so rounds down the barrel according to log notes....

any more questions sarcastically burning a hole in your head I can answer for ya?

I asked if you used Bluedot because that is what you use the most (10's of thousands of your post's will prove that).
I asked if your Pac-Nor was a 3groove (not a 3 grove)because they tend to blow-up 115gr Hunting VLD's not the 115gr Target VLD's.
will not ask you any more question's because you are a sarcastic a hole.

I asked if you used Bluedot because that is what you use the most (10's of thousands of your post's will prove that).Wrong My posts on Blue Dot don't take into account a lot of other different loading I do... you however take note of the Blue Dot, because you evidently don't like that powder in a rifle, because you ALWAYS have some wise ass derogatory comment to make about it..

I asked if your Pac-Nor was a 3groove (not a 3 grove)because they tend to blow-up 115gr Hunting VLD's not the 115gr Target VLD's. Thank you... just for you I will try to pay more attention to spell check...hope that pleases you

will not ask you any more question's because you are a sarcastic a hole. Well thank you... that way I won't have to address your wise ass comments, as you seem to love to defile any think I post that doesn't agree with your ivory tower philosophy.... Personally I don't find you to be a bad guy... but your following any of my posts, with some of these snotty questions or comments gets a little old...don';t understand why some like you seem to love to criticize guys who don't think exactly like you do...or do as you do....so if you are not asking me questions then we don't have to cross that bridge....and if you find me an 'a hole'... well sorry to rain on your parade...wasn't my intention.. but it also isn't my parade...
