Hi Guys,
Starting to think of 260AI loads and was wondering what powder, bullets, brass and loads (I understand loads are rifle specific, just curious) are you using. What speeds to expect from a 24 inch barrel?
Thinking of running ADI2209, 143eldx and Lapua brass
Cheers
Couldn't think of a better place to start than what you are planning.Quote:

My barrel was very picky tho.
129 interlock which I still use a lot for reds and shots inside 300ish
123, and 140 Amax were very accurate.
But I settled on the 130 berger VLD hunting and Win 760 powder. I have good case life, excellent accuracy and and velocity with a low ES.
One powder I haven't tried but have heard is good in the improved is RL16. But I am pretty content with how it goes now.

I was using Lapua brass, RL17 and 143gr ELDX for about 2940fps in a 24.5" barrel. I now run RL26 and 147 ELDM for 2900fps, which is much easier on cases than the RL17 was. Mines a 30deg Improved & long throat, not 40deg as per the Ackley design.
Thanks guys,
I am thinking of just running 2209 (cheaper haha) any luck with it?
I only used it for fire forming my cases, didn't try any load development. I wouldn't expect you would attain your best velocity with it but the 2209 is known for its accuracy.Quote:

2209 didn't show it was equal to RL17 in mine. RL17 was faster for less powder.Quote:

I am using Nosler brass at the moment only because I got a fair bit cheap.
Norma and Lapua also went well.
Once you start tinkering you will find out what goes best.

Yeah also think so. Not too worried about maxing out for velocity. Accuracy and a bit more fps will be good enough for me.Quote:

Some guys have the standard 260s running faster than my Ackley.Quote:

I look forward to your results.
If your in the south island I have some powders I have tried and don't use that you could try.
What rifle?

Are you going to neck down 7mm08 brass or fireform from 260rem?
Gonna fire form 260 brass

Mine was running laupa brass and hodgdon superprofrmance powder.
Mine had a 22" barrel and getting around 2900fps I think without looking up my data.
My standard .260 with a 20" barrel is only 40fps behind and just as accurate.

What bullets where you running at 2900fps?Quote:

My Tikka .260imp and my standard Tikka I've run Hornady 143 ELDX .Quote:

My imp had a longer throat and the bullets were seated way out with long mag and bolt stop.
The others are factory Tikka with a long mag and bolt stop fitted.
