I've been shooting Berger 140's out of my 6.5-284 over 52.5gr of 4831sc. This combo works great!

I was doing some load development yesterday with the 139 Scenar's and 4831sc, and got some interesting results. Every load I tried was showing a lot of vertical. I kept throwing more powder to it to reduce the vertical, but I got to a point where I wasn't too comfortable! I got up to 53.5 gr of 4831sc, and still didn't have pressure signs (slight machine marks on the back off the cases, but no ejector marks, or primer cratering/flattening, also no shiny markings). I was NOT shooting over a chrony during this session, so I'm not sure of velocity. All I know, is that the vertical was reduced every time I went up with powder, so I wanted to keep going up. I was meeting/exceeding 6.5-284 Shehane loads in a standard case/standard chamber, which made me question what I was doing, so I stopped at that point.

Anyone have any thoughts? I know the Scenar's are typically smaller in diameter when compared to other bullets in the same caliber, but does that make enough of a difference to go that much higher on the powder charge? I know, I need to put the chronograph up and see what I'm getting in terms of velocity, but does velocity matter if vertical is reduced, and pressure signs are minuscule?

Thanks for any info/advice,

Walt
