I've ordered some Sierra 155 Palma bullets and have been looking over the various loading manuals. I've got plenty of AA2230 on hand for 5.56 and I see it's used widely across the velocity spectrum for .308. Anyone out there like or dislike it?

2230 falls within the acceptable burn rate range for the M-14.
Why not give it a try and let us know how it goes?
Between 3031 and 4064 is the generally accepted range for this rifle and on the burn rate chart I looked at 2230 is closer to 3031 than 4064 so it's on the fast side of acceptable.
Probably a good thing for the bullet you are using.
Either way, good luck.

I have been loading 2230 with the 168 gr. HPBT Custom Comp Nosler bullets and I love it. Great accuracy with no signs of running pressures.

Accurate Arms shows a max load of 43.0 grains with the 155 grain Sierra loaded to 2.775". Note some of Accurate Arms load data can get a bit warm.

Thanks guys. My bullets showed up in the mail today so I'll get going on developing some loads. Will post results when time allows.

I did not know about that acceptable powder range. Thanks for posting it!

I took a look at Accurate's latest loading data and it shows both AA2230 and 2460. It appears that the max pressure is about the same for both 2230 and 2520 but 2460 is somewhat reduced. It does not show data for a 155 grain bullet but I imagine I could use that shown for a 150 grain and go carefully from there. I've got a small amount of 2460 on hand. I could try that too.
