6.5-06 Ackley Improved Data, This is my data so far, What's yours?

Hi All!

I've been playing with the 6.5-06 AI that I built 2yrs ago. As a little backgroud, It is a Remington 700 BDL, has a 26" Shilen Select match #4 countour 1-9" twist Barrel. Action is completely accurized and a trigger job has been done, trigger is 2lbs. Stock is a Fajien Laminate and is pillar bedded. Scope is a 6.5-20x50mm Leupold V-XIII with Target Turrets.

At first I wanted to shoot 140g Berger VLDs, it would not stabilize them, nor would it stabilize 140g Sierra Gamekings. Groups were no better than 1" at 100yds.

I decided to try 129g Hornady SST and Interbonds. Best velocity is achieved using RL-22. I tried Retumbo, but found it was too slow, and H4831 wasn't slow enough. I fired my test loads using formed Winchester 270 brass, in 90 degree weather. Top Velocity was 3322 FPS with slight pressure signs. Groups were 1/2".

I tried other types of brass to check for pressure and found that Hornady is a bit thicker than Winchester and Remington. With the same load, I had brass flow and I even blew a primer. In this rifle they need a decreased charge and can yeild the same with 1 less grain than Win or Rem brass.

I had the opportunity to shoot yesterday at 1000yds for the first time yesterday. I was able to put a bullet into a 4" square card board target on my second try. Winds were gusting 10-15 MPH. I'm Definately hooked!! Just need to learn more and get shooting. The rifle ended up shooting a 15" 3 shot group. Not too bad I thought.

Anyway, I'd like to hear about your 6.5-06 AI Loads, rifles and Longrange shooting.

Dan

Outlaw,

I really wanted to shoot the 140g Bergers. I fought it all summer last year, but I couldn't get it to group. I'd usually have a flyer or two when shooting 5 shot groups.

I also found that this rifle fouls pretty quickly. 20 shots and I gotta clean it. Take quite a bit to get the carbon out. Any body else have problems like this. It this unique to the 6.5mm bore or RL-22?

If any body wants specifics, I'll be happy to post them.

Well Dan I to have 6.5 and I to have had some problems with pressures so turned the necks I to use 270 rp brass there is more to work with out there on the end,my barrel was built by PACNOR . I'm using h4831sc and getting 2750 with sd of 5 average group size of 6" at 1000,shooting the horaday 140gr. Amax moly. In the begging I kept blowing primers also found out that we had a real tight chamber,but it is on an old 03a3 action weighs in at 20 pounds.

Nate,

I ened up settling on a warm load with the 129g Hornadys, but not too hot to blow the primers. I have gotten it to shoot under 1/2" at 100yds. My father has taken a liking to this rifle and I recently passed it on to him..... I ended up having an emergency that required funding and he asked to buy the rifle. I'm still doing the loading for it, so it is in good hands. However this has allowed me to focus on my .30-06 AI which is actually way more accurate.

I am also playing with a custom 7mm STW which is my infatuation , but not my main baby....

Just installed a Vortex Viper Longrange 4.5-16x 44mm for my father, he's been reading everything he can find on Long Range Shooting and I think it has him obsessed, It's really fun to watch the guy get so excited since I introduced him to Long Range Shooting this last year.

BTW, I've turned the necks from day one as I has a match chamber cut for this rifle. Pressure spikes were more a result of the Hornady Brass Versus Remington and Winchester.

Regards,

Dan

I found that my pressure spikes with the RP brass was a lot lower. Everyone keeps telling that i need to try the 120 amax or the berger vld.
I just had 7mm STW made and still working on breaking it in, doesn't even have 50 rounds through it yet. It's a benchmade barrel. Three groove, 26 1/4 long, 9 twist. Made by Blagg Rifles in Pendleton, Oregon.
I've been looking into the Vortex scopes also, what do you think of those? I just ordered a scope, Leupold VX-3 6.5-20x50mm (30mm) Side Focus. Anxiously waiting for it to arrive. Hoping it gets here before my next 1000 yd shoot. We have one coming up next weekend at our local range.
Do you have any load data from PO Ackley? Have you tried those lighter bullets at a 1000 yds? How did they do?

Re: 6.5-06 Ackley Improved Data, This is my data so far, What's yours?

Nate,

Those A-maxes are great, but don't overlook the 129g SST or Interbond. They'll shoot the same once you get a load developed. I did it because this rifle is purpose built for longrange Muley hunting and the Occasional Cow Elk. Some times a Bonded bullet would be needed and the SST and The Interbond are identical. They shot well out to 1000yds and still had enough energy to punch through a 6" Piece of pine Fence post.

I don't have any P.O. Ackley Data, but what I've seen is really anemic and uses fast powders. The slowest powder he had was IMR 4831 at the time, so it was no suprise that he didn't think the cartridge was worth while.

My 7STW is somewhat of a mystery, as I found it this last fall in a gunshop and got a smoking deal on it. It is a full blown custom but was left in it's original stock. I don't know the gun smith, but he did an outstanding job. It's a 1962 Remington 700 Action, Don't know the make of the barrel but it's 27" plus the Vias muzzle brake it has a 1-9" Twist.

This is what it looked like when I got it:

I have since put it into a H-S Precision Stock, I had to open up the recoil lug area and then rebed it. I also installed new bottom metal and installed the Leupold VX-3 6.5-20x50 SF with the Varmint hunters reticle using Warne Rings and Bases. (It's a great scope and works well for me at 1000yds) This is what it looks like now:

Looking forward to good weather to shoot my test loads and stretch it's legs....

This is the 6.5-06 AI with the Vortex Scope:

It's what my father wanted, so I installed it for him. As far as I can tell, It's a high quality scope at a wonderful price. We haven't shot it yet, but it seems promising. Since Dad is at entry level Long Range Shooting, it seemed like the best option for him. I'll update the findings after we finish getting him set up and then start letting him shoot the Longer Ranges.

Later,

Dan
