I am getting my POI/POA with the Winchester using the Speer 130gr FN load. These bullets landed 28" above where the 180gr SPs would have.
On the first shot you can see what I think is oil from my barrel. Even though I run a clean patch down the barrel before firing, there is a bit of residue that the bullet picks-up on the way down the barrel, then it leaves a vapor trail on the way to the target.
Anyway; I like this load and think I am going to load for it most of the time. (I still have some 110gr FMJs I got to get rid of.)
