6mm-06 or AI version info. ?

[ol mike]

Anybody have any data/info. on a 6mm-06 or 6mm-06 AI ?

Interested in 75 to 95gr bullets.

Thanks -Mike

I do not have any specific data right off hand but I have built both of these for customers and can tell you that for anything lighter then a 107 gr SMK, the 6-06 AI is just to much of a good thing.

The standard 6-06 will be much better suited for the bullets you want to shoot but even then, for 75 gr pills, its alot of rifle but much more practical then the AI version.

The AI will certainly work but with the lighter bullets you will not see much of a velocity gain over the standard version.

If you wanted to shoot some of the new 115 or 117 gr bullets or some of the custom 120 gr Wildcats when they are available then I would say the 06 AI would be a more practical choice.

Problem with many of the current bullets we have in 6mm is that we are already pushing them past the design limits as far as velocity goes. Choosing barrel rifling design becomes critical as does twist rate to allow the use of the sull potential of these big 6mm rounds.

Now with bullets such as the 95 gr BT there really is no limit to worry about. Only problem with these is that they are pretty light to make these big capacity 6mm rounds perform consistantly. They will work but the heavier the better in these two rounds.

I know this isn't the 6mm-06 but i have a 6mm WSM and it has a larger case capicity than either of the ones you are asking about. I use the Barnes 85 XLC at a vel. of 3850! It's very accurate and a blast to shoot[img]/ubbthreads/images/graemlins/grin.gif[/img] It's not picky at all, just about everything i have run through it, it likes.

I think you would be fine with either one you want.

Lovetohunt,

You just added to my comments. The 6-284 will drive a 95 gr Ballistic Tip to 3700 fps easily in most barrels of at least 28". Thats 10 grains heavier bullet then your using and only 150 fps less velocity.

With 107 gr SMKs I have personally pushed my 6-284 to an legit 3600 fps in the 30" Lilja with great results and five firings per case. But I backed her down to 3500 fps just to sleep better at night thinking the bore would last longer.

My point, the 6-06 and 6-06 AI would probably match your 6mm WSM right to the fps but with less powder. Not flaming your rifle in any way but the lighter the bullet, the easier time the smaller rounds have of keeping pace with the larger capacity rounds.

You would very likely have more of a velocity edge with heavier bullets as mentioned already.

Kirby,

I agree that the heavier the bullet the bigger the difference. But even with a bigger case capicity than the 6mm-06AI my 6mm WSM is very CONSISTENT. SD is excellent as are the groups.

By the way, the 3850fps is mild in my rifle. Could go 3950 to 4000fps if I want, but no need.

Here's a link with some load data (not mine). No AI though.

Scroll down about 3/4 of the way...you can click on the bullet weight, type of bullet, or powder.

I hope this helps.

Thanks for the imput.

I guess a 6-06 w/ the middle weight bullets is just a little too much of a good thing.
Thinking pretty hard on a 22 middlested.
