140 GR. SFT SP COL: 3.280"

H4350 52.0 2870 50,400 CUP


Keep in mind, this is the MAX powder charge. Start about 10% below and work up.

For my Tikka T-3 using 140 accubonds (should be same ballistics for Partition) is 58grs(max load). H4831 cci 200primers, win brass, 3.337 col. Getting sub 3/4" groups consistantly, with the occasional 1/2'' group.

Nosler #5 lists IMR 4831 as the most accurate powder in our test barrel for 140gr bullets. Starting with 49.5gr (most accurate) and 53.5gr being the max load. Start low and work your way up carefully.
