About a year ago I went through the loading process on my 30 06. I had 165 gn Nosler partitions and VV150.
If I'm honest I normally plumb for mid powder weights from A manufactures data. So I went in at 52gn of viht 150. Grouped and it was more like a shotgun pattern. Back to the drawing board so loaded with 48 gn. Group was astounding, 4 touching.
So a year down the line whilst chronoing my 243 fox rounds I took my 30 06 just out of interest. The group was still spot on , However speed was only 2500f/s. I'm not going to change a thing, but just felt a bit disappointed.
