Thread: Best adi powder data

I was also going to make some comments.
I load for a 358win using 308brass. With a 225 gr projectile I have a max load of 49 gr by book data for velocity in the 2450fps range.

So when I look at data saying a max of 45 gr under a 150gr bullet I'm going to ask questions. That's a lot less. (Yes I get that the smaller bore means less bullet to push on)

I also know that with the brass I'm using 48gr is a slightly compressed load let alone 49 or even the 51gr I gave seen suggested of AR2208/Varget in a 308win family case.
So as everyone else has said, look at multiple sources for your reloading data and until you have an understanding of the pressure effects of a longer bearing surface or a thicker copper jacket or solid copper bullet work with data that tells you exactly what bullet they used and use the same bullet.
