I only use IMR 4350 for my 8mm mauser. Originally I used 4320 and found a sweet spot with 170 grain spitzers. But they discontinued it. So I switched to 4350 and I primarily use 200 grain ones now. It's giving me a pretty stable and accurate grouping so I'm happy with it.

My .270 Win and Sierra Game Kings in either 130gr or 150gr seem to love IMR4350.

The only thing I don't like about 4350 (and 4320 for that matter) is that it's powder is not spherical. Sometimes it causes my measure to be a few 10ths of a grain off, so I'm never loading max weight.

I don't have an automeasure, just a couple of Lyman 55 measures. I tinkered with my process at first measuring individual charges until I found a pattern that was consistent for me. 3 raps with the knocker every time.

On the other hand, I rarely shoot for max load for the exact reason you posted. I've found that max weight doesn't always equate to better accuracy.
