Thread: Powder for 123 Amax in .260

What powder do all you .260 guys use with the 123 Amax?

nzfubz sent me some to sample and I finally got around to testing them.

I used 2209 and while scary accurate I could not get them much above 2950fps without reaching pressure, that I am comfortable with.
I use the same load with 129/130 class bullets and have them going as fast but with no pressure and a long case life.

Happy to stay at 2950 as I have yet to shoot a group over .3 with the 123 so far. Very happy with that for sure, but would have thought over 3000fps with the Ackley would be expected.
Faster powder maybe, but I thought I would pick some brains before I try to anything else to save some time.

Cheers.
