What % was your case fill at 92 grains?I'm going to revisit all the sweet spots from both powders here shortly! Need to clean a barrel and process brass, then I'll be back on it. Those N570 groups were looking

Not certain, but I would say close to 100%. At 93.5 I started seeing it affect OAL without the drop tube.

were you thinking about trying n568 also?

Funny you should ask because I was just talking to another 300 NMI guy about N568. It usually works great with the lead options, especially 225/230/245's I've shot in the past. N568 would likely yield about the same velocities as N565* (edit), however take more powder to get there. So I imagine it will shoot well, mostly would come down to case fill. May not be able to pressure up before running out of case capacity.

In the heavier bullets I've had some amazing ES/SD's with it! That & H1000 might be contenders depending how these other powders pan out
