250 ackley new build many????

Hornady is making brass and ammo this year for the 250 Savage, so you will be able to find brass to use shortly. I have ordered some already.
Quality cartridge will make you properly headstamped brass for your rifle, but it is not cheap, you must order a minimum of 300 pieces (if memory serves) and you will need to send them a fire formed case from your rifle so that they can verify your chamber dimensions (as there are several versions of the 250AI with various shoulder angles). I have done this, but will save this brass for when I have found a load worthy of its use and fine tuning.
To date I have been using Winchester fire formed brass in my 250AI, but am still trying to find a good load. Am trying IMR 4350 and 4831, WXR and Vihtavouri N560 right now with 110 gr AccuBonds. Still need more time at the range to finish these test loads. Accuracy is better than 1", but velocities have not gone much higher than 2900 fps yet. Am hoping to reach closer to the claimed 3200 fps (100 gr), but with the heavier bullet expect it to be closer to 3100fps. Have not yet tried the new Reloder powders. Will look at them once I have finished with these test loads.
My rifle is a rebarrelled Rem 700 LH CDL with a 24" barrel. It will produce less than 1" groups with the Winchester factory load.

Welcome aboard, 25FAN; always glad to see new people sharing in the fun. I ran a QL using a 24 inch barrel to give you an idea of what you might see.
Code:
Cartridge : .257 Roberts Imp.
Bullet : .257, 115, Nosler BalTip 25115
Useable Case Capaci: 54.511 grain H2O = 3.539 cm³
Cartridge O.A.L. L6: 2.775 inch = 70.49 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Alliant Reloder-26
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.

What Pmax would you think new manufactor Brass and modern Rifle?
Running Reformed 22-250 Brass 65000 Pmax?
What do you think of 6.5 Creedmoor small primer Brass?

As I do not have the experience of other handloaders here, I will not make any suggestions as to safe pressure levels for brass. I stick to the recommended loads in manuals of QL.
I also am not versed in small primer brass, nor have I ever used it. Others here are more knowledgeable on this topic as well.
Perhaps someone will be able to advise on the variance in case capacity between the 250AI and the 6.5 Creedmoor?
I'm sure DrMike will get you the 250AI QL data shortly!

The PMax is 52,997 according to the QL data, I am not familiar with necking up or down with different brass, so I cannot help you with that question. Hopefully some experienced handloaders on here can answer those questions. Listed is for a 24 and a 26 inch barrel.
P.S. Oops, I did not notice that RL-26 will overfill the case, disregard this powder, I would not use it, use a faster powder like Dwh said below, RL-15 and RL-17 will work great. Also try RL-19 as well.

I use both formed 250 brass and 22-250 brass in mine.
The following runs are what I use but NOTE: the pressure is moved up so start low and work up.
On the 22-250 brass, I use imperial wax on the necks and run them through a straight 250 Savage die. Then load on the high end of standard 250 and shoot. I messed with false shoulders for a while but didn't see the difference.

What is your intended purpose for this rifle?
Bench rest , target or competition, or even sendero hunting; leave it at 26" as you won't be packing it around in the field much.
Open field or mountain hunting, where you will be packing it lots; 24"
Brush and field hunting, And/or for varmint hunting, where you want a shorter, lighter, quick pointing rifle; you could go down to 22".
Personally, I would go no shorter than 24" and look at other ways to lighten the rifle to make it more lively in the hands. (And make sure they do a good job on reckoning the muzzle.)
And this would be dependant upon which Savage model you have. Suggestions could include: Flute the barrel or replace with a lighter barrel contour or a carbon wrapped barrel from Proof Research or Christesen Arms. Replace the stock. It is amazing how lively a longer barrelled rifle can feel in your hands when the rifle is balanced properly for your intended purpose.

That's the load I run.
It's a comfortable load and easy to shoot.
Just fwiw, in my experience Ackleys don't show pressure in the same manner or at the same levels the non- improved cartridges do. There are times that the stiff bolt lift; ejector marks or primer flattening doesn't even show until upwards of 70k, which we know is the danger zone, so make sure you keep an eye on your work up.
While the 250 AI is, in my opinion, a terrific cartridge, it's not going to be 25-06.
37 gr of RL15 will shoot bugholes with the 110 AB at around 2850 from my rifle.
42 gr of RL17 will do the same at around 3000 fps. (mine is a 24"btw)
You can see the Hunter load in the link above.
I would think RL16 would be good also but haven't gotten around to messing with it in this rifle yet.

25Fan,
I moved my 250AI on, but mine had a 25 inch bbl that I later trimmed to 21".
Was mainly using 100g Speer Hot Cors and 117g Interlock BTSP loads with R17. After the bbl chop I settled for around 3050fps for the 100 grainers and 2900fps for the 117s. They were pretty mild loads it seemed and shot really accurate for me.
An incredibly accurate fox load was the 85g NBT over H4895. This was capable of stacking three shots touching regularly at 125y. In fact the first 3 shots out of the rifle were with this combo and all three went in one hole at 125y on my home range!
I recommend 4895 for the lighties in the 250AI.
Good luck, stay safe and have fun!
