Thread: 25-06 why hasn't it achieved fame and success in New Zealand?

I have a 25-08 built on a Tikka m55 - with a 24 inch barrel not much slower than my 22 inch barreled Tikka T3 25-06.

I think a 2508 AI would be perfect !

Nah 257AI........ would like to AI my Savage .250 but can't find a reamer anywhere in N.Z.

I remember that the 250 AI had a huge increase over the standard round - something like 25% which was the biggest increase Ackley had with any modern rimless case

Greetings Moa Hunter,
The huge increases in velocity were often accompanied by huge increases in pressure. Often the velocities were estimated (guessed) rather than chronographed so the actual results were much less. Huge increases were claimed for the .30-06AI but actual pressure tested loads showed minimal improvement.
Greetings Pushover,
I had a .30-06AI for a while, fire formed cases and just neck sized. Worked fine for my loads and did not get into tight case problems. Had I done so I would have tried firing a light load 35,000CUP or less to see if it produced a easy chambering case as it has done with my .308W.
Regards Grandpamac.

I might be interested in going halves in a reamer @nor-west if my ones shoot well enough.

What rifle is your 250 in?

There ya go. Obviously some of the recent "Ackley Improved" are not on the list. Keeping in mind that the recent AIs were obviously never developed by P O Ackley himself. That includes some on the list.

Interesting numbers. Is it reasonable to just fire std loads to fireform and then neck size only for subsequent loads?

Ie, not using Ackley dies at all

Yep, I did that for years with my 257AI. Eventually though I really needed to bump the shoulder on my brass as bolt close was getting tight after about 8-10 firings.

True Ackley designs have a crossover point on the shoulder of the unfired std case that headspaces correctly with the Ackley chamber shoulder. The design minimises any risk of case stretch at the base (and possible separation) on firing. That's how Ackley designed them. The more modern versions that have got onto the Ackley bandwagon I cannot comment on.

@Mathias I have the same problem with my 6.5 Swede Ackley. Although I have dedicated Neck Sizing and Bullet Seating dies for my AI (modified 6.5x55 SM) after about 6 firings and they are getting tight. Unfortunately the FLSing die I have doesn't quite restore them to original. Will do something about the die one day, when I get roundtoit.

Thanks for the experienced info guys. I think id be happy with 6 to 8 loadings anyway.

Gives some ideas to play with. Apart from the savage I particularly like the numbers on the 6.5 x 55 and 7 x 57

Bump because I can haha

Ok, I'll take that bait: somewhere back in this thread it was determined that the .257 Roberts or .257AI, either loaded with 115gr Berger or 115gr Nosler Ballistic Tips was the best 25-cal for deer in NZ, surpassing the 25-06 in lethality, and with a small but significant reduction in recoil and muzzle blast.
Is my recollection incorrect ?

I reacon the 25-08 is better

Why not? While we are on the subject, what about the A-Square wildcat, the 6.5-08 that became the 260 Remington? Almost the same performance in a short action... Yet there are only a handful of factory chambered rifles to be had, and factory ammo makes unicorn shit look plentiful.
