    ? Same point of impact or not ?

    At this moment in time i am useing VV N150 38.9 grn in Lapua Brass neck sized.

    This gives me 2600 fps

    I am changing to VV N560 But dont have time to do a full load develpoment if i use the load that will give me the same fps eg 46.5 grn 2600

    Will i get near as dam the Same POI. Or will i need to start a gain.

    Different burn rates and pressures will move the POI, maybe not by much but it will, you HAVE to check it.
