Caliber would help. I have the last pdf of their data. 3100 was discontinued many years ago 2700 hasn’t been yet.
Exactly, I haven't seen or used AA3100 for 10 years at least. Worked pretty good in 338wm rifles though. Seemed comparable to RL19. OP is probably wanting old data, because he knows 3100 was discontinued.
Yes I know, that link is to AA data version 3.5. Very old. Looked through all my AA manuals never did they recommend 3100 for 264 Win mag. Closest is Sierra using 120 54-59 grains, in 140 it’s Magpro or 8700. 3100 is 4-5 steps faster than 4831, closest is RL19 which is right next door.
Pretty much what I said, but more information for the op is a good thing. I was just going off the top of my head from when I was loading a lot of different things in my 338wm. Back in the late 90's and early 2000's. I used 3100 and RL19 for a spell with lighter bullets (up to 225gr). I actually preferred AA3100 over RL19 back in the day. It was a great powder and I was disappointed when they discontinued it. Since Mr. beretzs commented on the subject, I'm sure he's ran truckloads of 3100 in his 338wm as well. If not, I'd be surprised, he missed out. As for loading it in the 264wm, I'd not try it unless I had some good data suggesting it works well. That's where I'd start pulling out all of my old load manuals and doing some homework... Speer, sierra and Nosler usually listed loads with AA powder.
