Good deal.

Go ahead and load those Winchester 308 brass till they're trashed. Then get Lapua 260 brass, guarantee you'll love them.

I have a 1000 win 308 that I was going to neck down for my 260 but decided to get Lapua,
excellent stuff.

+1...Lapua brass is unbeatable, IMO. It's all I run in my .308 Win. I have tons of other .308 brass (mainly Hornady Match, which is also good brass) that I use for random testing, but for my precision loads, I use Lapua.

 

[riflelooney]

OK......convinced me.....gonna try the Lapua

 

[stomp442]

By far my favorite 6.5 Chambering. Good Choice.

Hmmm? Re 22 is one I have not tried in my 260 Ack..I may have to..

IMR 4831 is my powder of choice,much prefering it over the Hodgins version..It gets me 2960 with 140 VLD's.. Like the others,Lapua brass all the way..

Santiam Imr 4831 my gun just does not like it,,,,plus it seemed to develop pressure FAST.....2950 was it......got to 3035....and auto deprime on the case!!!!RE-17 was ok and no higher velocity than RE22....mine is a standard chamber not a match 48.3-49 grs works with Moly bullets in MY gun..may b too hot in others...also that's in Win .308 brass......49.0 is safe in my gun ...and just about it unless heavy compression is used.....I think if the leade was .35 longer it would be better...at that point I think RE-25 would be worth a try as well as IMR-7828,,,But I am very happy with it as is and not touchin a thing......I had several 6.5-384 in the past and they were finicky in my opinion......a few 6-284///22-284 7 mags .264mags 300 mags all in all this is the best darn thing I have used to date......2nd Best? 7 mag 162 amax

I wish I had bought a 260 before I even thought about 6.5 284.

Live and learn,
but I do wish I had all that time and money spent on 6.5 284 back.

The very next barrel I get WILL be a 260 Improved. ( By the way I think we should only say '260 Improved' because I dont think PO Ackley had anything personally to do with this particular chambering.)

 

[Santiam338]

260 Improved it is.. Re 17 is the one I didn't have luck with..Love it in other calibers... I thought maybe Re 22 would be to slow to get that kind of velocity,but see I have more experimenting to do.

 

[riflelooney]

With all due respect I will continue to refer to the .260 40 degree shoulder fireform the cases based on the same datum line as other .308 based cartridges from factory chambers as Ackley improved. or should I say olin t-65 Ackley type modified??? which was one of the names the .308 had during experimental development for the military it was just refererd to as t -65 with varients...Parker Ackley never had headstamped .260 brass... but he sure was aware of the t-65/ the 6.5-308 had many versions such as the .264 Hollis,,,260 AAR to name a few////I will call it a Ackley improved all the same.... Thank you....For there would likely be very little SIMPLY improved without P.O Ackley

 

[Wachsmann]

riflelooney, what angle does your case neck have for the Ackley improved verision have. I have a tikki 243 and I'm serious thinking about changing it over to the 260 improved version. Well its the wife' s gun actually.

 

[riflelooney]

I am not sure what your asking....shoulder angle? 40 degrees...or case neck taper from mouth to shoulder?

 

[Wachsmann]

it was the shoulder angle....Sorry about the confusion....I just have seen some different versions on the Ackley improved.
