~ 20 years ago all I shot was 180 Partitions in my 30-06 Win. M670. I had heard of how inaccurate Partitions were so worked at getting them as consistent and straight as I could. The first 5 shot group was covered by a dime. Basically one ragged hole. Similar groups followed. Well I felt I didn't need that much accuracy since just slapping them together produced 1" 3 shot groups and took a lot less time.

The load was 56g of IMR 4350 in Winchester cases and a CCI 200 primer. 2650 FPS
