Shot a few groups this morning, but wind got so strong I couldn't keep anything on the bench and ran out of heavy objects to hold down the light ones so gave up. Got to 30.4 gr. and was doing 3180 FPS no pressure signs, but would need to work at getting much more in the case. Had a little vertical in the groups but got it out with seating depth. Not really any better than most other powders I have used, but is very clean! Will test more when the weather warms up more.
