Lee, I like the Ackley. 3-shot groups at 550 run an inch. 140 jlk at 3070 is a sweet spot, yet 3200 is there if you need it, with good brass life. Easy "minute of motel TV" to 1600 off a bipod. Fireforming loads at approx 2600 are very accurate typically. Recoil in a 12 lb rifle is pleasant. Case stretch essentially non-existantThinking of building one or the other.

The Ackley version in my opinion is not worth it
James, haven't shot the first bbl out yet. Throat has moved .004 in 800 rounds. Never have let it get hot. Rl-22 and vv-560 give great hunting accuracy and 3180 fps with good brass life, but vv-165 at 3070 is better on both counts, and allows about double the number of shots in a string re: barrel heat, and eliminates torque when firing off a rest. Expect in apples-to-apples test, your 280AI would get significantly better bbl life.Just curious, what kind of barrel life are you getting with this combination? What kind of powder do you prefer? Love my 280AI, just wondering about the 6.5's.
I've shot both versions and this is what I've found. The Ackley version in my opinion is not worth it, here's why. When loaded to the same pressure the Ackley version gives an increase of around 3%. That's not much over the straight 6.5/06. A lot of the Ackleys typically give 5% or more.
Barrel life isn't great, somewhere between 1200-2000 rds (about what you'd get from a 6.5/284). Each barrel is different. This is for competition use. Minute of Bambi accuracy will increase the barrels useful life.
B, My results with the 6.5-284 vs AI differ from yours. The 284 accuracy load to equal the AI accuracy required h4350, at 2975/142 SMS, generating bbl heat and borescope documented fire cracking. 1000 yd competitors over the years settled on h4350 and h4831 despite leaving significant case capacity unused, and dropped it because of poor bbl life. my 6.5AI brass lasts 12 reloads, so negating the "spend more time shooting" argument. The gap 4S/6.5 Saum would be an excellent duplicate of the 6.5-06 AI without the fireforming hassle, and would give it a go if not already fully invested. dont doubt your experiences/results, and as to opinion, I'll take a brunette over a blond or redhead as a general rule. SeymourIMO, this is pretty spot on. As a comparison, I have a 6.5-06AI built on a Howa and a 6.5-284 built on a LA Rem 700, they both shoot equally well. The 6.5-06AI shoots the 130's and 140's between 50-75fps faster. I use Lapua brass in both. My 6.5-06AI has a 27.5 inch barrel and my 6.5-284 is 26in. My accuracy load in the 6.5-06AI with 140 Bergers runs 3170fps, accuracy load in the 6.5-284 with same bullet is 3095fps. Both will run faster but the groups start to open up so there is no point in pushing them harder.
For me, the biggest difference in the two is certainly not the velocity but rather how much easier the 6.5-284 is to load for from scratch, compared to the 6.5-06AI or even straight 6.5-06. The 6.5-284 has excellent brass available for it and it's just sooooooo darn easy to load for right from the beginning that, after having both, I would never do a 6.5-06, AI or not, again. The 6.5-284 shoots nearly as fast and you'll spend a lot more time shooting and less time in the loading room.
We all love velocity and I'm not different but as I've gotten older I've come to the realization, if you want more case capacity, get something with a bigger case to start with instead of improving things. I think if a person wants a speedy 6.5 something or other, there are better choices out there. The necked down WSM cases for a 6.5WSM seems to be a rather popular choice and with some of the heavier 6.5 bullets, like the 160's or 155 Berger, something with more case capacity could make for a sweet long range hammer.
BUT, if a 6.5-06 or its AI version is just what you have your heart set on, then that is what you should go with because after all, it's your money, spend it how you want.
I've read all the posts and find them very interesting. Lots of good information. I haven't decided yet.
The action I have is an 09 Arg. I'll use a stainless steel barrel 1-8 or maybe 1-7 on the long side maybe up to 30".
Very good comments. Thank you very much.
Boy that sounds like a big buck story. I bet R33 would make the heavies run. MattI use H4350 in my 6-284 with 75's but that's all. Only use slower powders, with the heavies, in either of my 6.5's. In fact I've been meaning to try N570 in both of them but haven't gotten around to it yet. N570 seems to be one of those special powders that produces pretty healthy increases in velocity without going crazy on pressure.
