My Featherweight 06 really likes Nosler 165 grain BTs loaded 100 to 200 fps below maximum with H414 or IMR 4350. It shoots OK with max/near max loads, but really key-holes with the slightly milder loads. I'm going to try to achieve the same results with 165 Accu-bonds. Early results again indicate that less than max level loads are going to be the key. The gun also likes 150 Rem core locts loaded pretty hot.
