Have used 139 Hornady, 140 Accubond both with h-4350 with good results. Rifle likes the 120 bt's real well with varget but I haven't shot deer with it [yet]. Remington 700 SPS stainless.
Im not sure what size groups youre getting with the H4350, but if you happen to have any Varget or RE15 lying around, Id try one or both of those with the Accubond and 139 Hor. I load anywhere from 40.5-41grs of Varget with the Hornady in a couple of buddies rifles and it plain rocks. Ive loaded H4350 and wasnt impressed.
