Actually safer than that. I started at the lowest recommended powder load and went up 1 gr each string on my ladder to the top, watching for pressure signs along the way.
Then as I found a relatively close load I would back down .2 gr and up .2 gr to the previous and next full grain load(total 2 different loads before and after the whole grain load) . This worked great with the NAB's, but still haven't found a suitable load for the corlokts. I have only used the AA4350 so far, bc as I said earlier I like to consolidate powders as much as possible for as many calibers as I can. I also used the AA4350 in my 300WSM just yesterday, using the same 150 gr NAB's, and with 64 gr of powder struck upon a nice .655 grouping, again starting from the bottom of the recommended powder load for that caliber. Also got a decent .750 group with 66.0 gr as well. I am happy with the NAB's performance, both in my 06 and the 300WSM, I'd just like to be happy with the corlokt bullets as well, wo having to use another powder. Worst case scenario is that I just stick with the NAB's, which all in all, isn't really bad at all.
