I had started out using Hybrid 100V but I'm getting quite a bit above max published load data and not getting where I wanted to be. At almost 2 grains over max, I'm still not to 3100FPS, even though I'm not showing any signs of pressure...need ejector Mark's not sticky bolt.
So I picked up a 5lb jug of R-22 to give it a go. So far I'm a little over max Nosler data but not much without any pressure signs...looking like I'm within a couple 10ths of the next noid but still shooting pretty decent.

This target was shot at 500 yards yesterday with a mirage so bad that it looked more like a flag than a target. So I didn't even bother with a 5th shot. Kind of wish I had...of course you couldn't see the holes in the paper in those conditions, so I didn't know until I walked down to pull the target.
The wind was acting a bit crazy too! At the bench the surveyor tape was showing the wind at 4 o'clock, basically coming over my right shoulder, but the surveyor tape at the target was from 9 o'clock...I'm guessing is was bouncing off the 400 yard berm.
With 53.7gr of R-22 I'm pushing Nosler 130gr RDF at 3050fps average the SD 15 and SD 25 (IIRC)...it looks like I might get closer to 3100fps and the next noid before I see pressure signs. Normal disclosure on working your way up to my results.
Anyone found the magic recipe to break the 3100fps mark with R-22?
