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

I am assembling the pieces to build a 6.5-06 or 6.5-270 Win. I have two 6.5 WSM rifles and a 6.5 -284 currently. I started with two M70 Westerners in .264 Win Mag.

The advantage of the 6.5-270 or '06 is the longer neck. You can size half way down and still have a section unsized to center the neck in the chamber. I want a longer neck than my 6.5-284.

I have also found that Vihtavuori N-560 power is well matched for the 6.5-284 case volume with 120 to 130 gr bullets. If all you want to shoot is these bullets, 130 AB, 129 SST, and 120 Btips then you do not need the larger case volume to achieve the same velocity.

What I need help with is dies. What are you using for sizing dies? What have you learned about sizing? I intend to use .270 brass from Norma (Nosler). I have access to annealing machine to extend case life.

I will use the reamer to cut a Wilson seating die from a blank. This is the only way to seat. I have 11 Wilson seating dies in rifle calibers.

Please help with your sizing die recommendations. I could use a reamer too.

Sizing initially was done to make the first loads by running .270 Brass part way into a .260 remington die. I later ordered a set of dies from RCBS and this is what I currently use for loading the 6.5-06AI. Check to see if RCBS doesn't already have that one on hand.

The reamer came from Dave Kiff of Pacific Tool and Gauge (PTG) If the 6.5-.270 Doesn't exhist, He will design one for you. I'm guessing that it would and that he can make one for you.

Annealing isn't necessary as only one minor sizing step is required and if using virgin brass. You may want to turn your necks as well.

Hope this helps,

Dan

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

RCBS dies are rarely accurate. Take the stem out of the bullet seater and turn it upside down. Put a VLD bullet in the stem point down. I will bet that the stem makes contact on the point rather than the ogive of the bullet. The button on the size die is at the end of the decapping stem so it will have the least support and most wobble possible. So we will not use the button and avoid 25-06 brass with RCBS dies. The size die body without the stem might resize OK but if you check for concentricity with a runout tool I would bet on Redding or Forster dies being closer to true than RCBS. Besides RCBS dies are expensive!

I can come up with two plans for resizing 6.5-06 from 270 Win or 25-06 brass.

Redding makes bushing dies in 25-06 Ackley Improved. That die might work with 6.5 bushings. For example I use a .296 bushing in the 6.5-284. A titanium carbide drill bit might be necessary to open up the neck. It is a hardened die so this is not a walk in the park. Cost is $75.19 at Precision Reloading
Precision Reloading: 25-06 Remington Improved 40

The second is CH4D has a 6.5-06 die set offered in 4 shoulder angles, listed for $82.
Caliber List : CH4D

Has anyone tried either of these or ideas or have an opinion?

I have a set of the custom Redding dies that I ordered from Grafs, expensive. They work okay but the sizing die is a small base die that works the brass too much for my liking. I then bought a hornady 6.5 neck sizer that I use quite a bit but eventually they all needed full sized. After sticking a couple of cases in the small base die I purchased the 25-06 Ackley Redding bushing die. This die works perfect for my rifle. Not sure of the bushings off the top of my head but I think .288 works good for 270 brass and .286 sounds right for 25-06 rem brass. I did not have to do any modifications for the die to work right.

Outstanding. Thanks fellow Bronze Member.

Note that the bushing dies come in neck only and full length. I have only purchased full length in the Redding dies so far. It still seems that a dedicated full length die is necessary after about 3-4 firings to push back at the junction of the shoulder and reduce the diameter of the neck below the bushing. This is more noticeable in the 1885 falling block than in the Model 70 bolt action. The greater camming power of the bolt action is apparent.

I have a Forster bushing die that pushes the shoulder every time, but does not fool with the base of the case where it expands just above the extractor groove. It works with a tight chamber. I have not used it for even 200 rounds yet.

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

I am finally shooting my 6.5-06 AI .291 Neck.

New Model 70 MOA trigger. Shown here fireforming. Bell & Calson stock was stiffened with 4 layers of graphite fibers in the forend. The Model 70 recoil lug was bedded with Marine Tex gray and Accuglass and Accuglass Gel were used on the sides of the action, the rear tang lug etc. The stock was sent to me (I ordered the upscale pad and long length) from Bell & Carlson with a banana curve to the barrel channel and action inlet. I sent it back and B &C held the rifle for 5 months then returned it as is. They said that the warrantee did not apply because I inletted it for the one piece floor plate. B&C are junk and the Company is not even proud of them. I will send you the letter and I will wait for a McMillan next time I want a thumbhole composite stock. It took a lot of body work to fix the factory inlet. The blank weighed 3 pounds before I started. Now it weights 3.2 pounds. I have wood Model 70 stocks that are lighter. Good thing I got their lightweight model without the aluminum bedding block.

After this session the MOA trigger was replaced with the Timney aftermarket and adjusted to 24 ounces.

For load development, the rifle wears a Sightron 10-50X60mm scope in Warne detachable rings.

I will be using the 129 Hornady SST and 130 Berger VLDs. The twist in the Rock Creek 5R barrel is 1 in 9. I shoot the 140s in one of my 6.5 WSMs

I think that VV N-560, MagPro, H-1000 and IMR 7828 will be the best powders.

MagPro puzzles me, it is the best velocity powder with 140 gr in the 270 WSM but is too fast for 6.5 - 284 with the 130 gr bullets. It behaves like IMR 4831 there.

Dano,

Because I am going to use the same 129 and 130gr bullets, what have you learned about powders and primers?
