17 Rem Posted October 7, 2009 Report Share Posted October 7, 2009 Anyone got any experience of one? I'm interested in one with 40 degree shoulder. Wondering if anyone knows how they feed from a magazine or what velocities are really achievable. Link to comment Share on other sites More sharing options...
Vermincinerator Posted October 7, 2009 Report Share Posted October 7, 2009 Hi 17 Rem, What exactly do you mean? Do you mean a quarter inch bore calibre such as the 250 savage Ackley Improved or are you actually refering to 22-250 Improved? Ian. Link to comment Share on other sites More sharing options...
17 Rem Posted October 7, 2009 Author Report Share Posted October 7, 2009 250 Ackley Improved, NOT 22/250 Ackley Improved. Looks to provide 25-06 performance with about 20 grains less powder! Link to comment Share on other sites More sharing options...
Vermincinerator Posted October 7, 2009 Report Share Posted October 7, 2009 17 Rem, I only asked as there is no such animal as a .250 Improved, simply because there is no parent cartridge called a "250" The 250 Savage Improved is the only one that mentions 250 in the title. Other then that there is the 257 Roberts Improved. Ian. Link to comment Share on other sites More sharing options...
Andrew Posted October 7, 2009 Report Share Posted October 7, 2009 And if the 250-3000 Savage is what you're talking about, just get a 257 Roberts. Brass will be a problem otherwise. If you do get a Roberts, don't bother making an Ackley out of it. If you pick the right powders you can get close enough to the 25-06 so that a deer wouldn't know the difference. I shoot a Roberts; sweet. Shot a 257 IMP as well built on a Small Ring Mauser 98, too. Nice as well.~Andrew Link to comment Share on other sites More sharing options...
17 Rem Posted October 8, 2009 Author Report Share Posted October 8, 2009 There is no cartridge other than the 250 Savage with '250' in its' title (as far as I know), so yes, unsurprisingly I am asking about a 250 Savage Ackley Improved! I don't want a 257 Roberts. Which is why I asked about a 250 AI. Does anyone actually have any experience of the 250 (3000 Savage for clarity) Ackley Improved?

Vermincinerator Posted October 8, 2009 Report Share Posted October 8, 2009 Mick who works for Norman Clark shoots one but it does not get anywhere near 25-06 ballistics. The .250-3000 savage case is almost 5/8ths of an inch shorter then the 25-06, so even in improved form has substantially less powder capacity.

17 Rem Posted October 8, 2009 Author Report Share Posted October 8, 2009 Thanks, Ian. The Accurate Reloading website (which, incidentally, calls the cartridge 250 Ackley) lists a max load for the cartridge with 75 grain bullet as attaining 3735 f.p.s. with 45 grains of powder. It also lists a max load of 62 grains of powder in the 25-06 as managing 3799 f.p.s. with a 75 grain bullet. Not much of a velocity gain for an extra 17 grains of powder, is it? Extra case capacity isn't everything, some cases are more efficient than others. Link to comment Share on other sites More sharing options...

My .257 Roberts Improved shoots 75grn V-max's very accurately @ 3580fps with 51grns of Vit 550, I could cram in another 5 grains of powder but dont think its necessary. Ian.

baldie Posted October 9, 2009 Report Share Posted October 9, 2009 I think that this very interesting thread, proves one very important point. If you want a hot cartridge, there is a 100% chance its been done already, and that a trawl through the reamer book, and an hour on the web, will produce some very exciting information. This cartridge looks very interesting indeed. Keep us informed marv. Link to comment Share on other sites More sharing options...

You can see that in a 308 vs 30-06, 22-250 vs 220 swift, 250 savage vs 25-06, etc. If you wanted to shoot bigger bullets you'll start seeing more difference. You could also consider a 25 Souper (308 necked to 25). Not sure what dies would be for an improved 250 savage vs a souper though. If you don't already have a reamer picked out, you could try to get one that used a 260 rem case and necked it down in bushing dies.

Ronin Posted October 10, 2009 Report Share Posted October 10, 2009 You could also go for 25-284. Would be a good performer, downside of .257" bore is limited choice of bullets.... Great calibre, like the 270, just lacking in choice. Link to comment Share on other sites More sharing options...
17 Rem Posted October 10, 2009 Author Report Share Posted October 10, 2009 Thanks for the advice so far. The 284 case just doesn't interest me. I have no real desire to burn 50 or 60 grains of powder. It's not that I'm tight or even particularly recoil-shy- I just don't see the point when gentler cartridges will do anything I want them to. 25 Souper is interesting, though. Menial 1, thanks for making me laugh- please don't blow your hand off! Link to comment Share on other sites More sharing options...
Ratwhiskers Posted October 10, 2009 Report Share Posted October 10, 2009 l know a chap that's got one in a savage action, and it's murder on Roe deer. Would make a nice charlie flattener with the right bullet as well me thinks. Link to comment Share on other sites More sharing options...

Zaitsev Posted October 22, 2009 Report Share Posted October 22, 2009 Quickload gives a load of 41gs of N135 24 inch barrel 75gr Sierra at 3400fps. That give you some idea? Regards Gareth Link to comment Share on other sites More sharing options...
17 Rem Posted October 24, 2009 Author Report Share Posted October 24, 2009 Thanks, gents. If I don't get some reassuring reports, some kind of 25-308 Improved is looking likely..... Link to comment Share on other sites More sharing options...
