I am in the process of building a 7mm stw with a 30 in bbl 1 in 9 twist. I am looking at several different bullets to try and want some real world experience from any one here who has tried them. 140 and 168 grain berger 140 and 160 accubond 139 and 162 sst 162 amax I have ran these bullets in ballistic calcs. and with the velocities expected the 140s are flatter and have close to the same drift values out to 1000 yds. The energy is also only slightly better with the heavier bullets. velocity used in calculation was 3600 for 140 and 3300 with 160. Im not looking for opinions just actual experience from other shooters.
