Ball powder meters great, stick not so well, though there is quite a variance between them due to the size of the kernels of various powders.
Here's how I look at it. For high volume, ie pdog rifles and loads, I use ball powders and make sure the load is safe in the summer as that's the only time I usually shoot them. I would also use them in the winter if need be, as in reality 100 fps loss isn't going to make that much difference at normal ranges. Testing would need to be done, however, to determine any loss of accuracy.
For lower volume stuff that's used for "more important" hunting, the Extreme line from Hodgdon is hard to beat IMO. Powders like Varget, Benchmark, H4350 and most of the Hodgdon stick powders are supposed to be really insensitive.
Like Rock Knocker, I really like IMR 8208. It meters well for a stick powder, and is more insensitive than ball powders. Benchmark would be another that is very similar to 8208, they both work well in the 223 class of cartridges.
