Re: 162 sst b.c.
Fed 215 primers, 24" tube, loaded on the lands. With this bullet/barrel combo, my speed topped out at 2950 at 68.5 grains. After 68.5 my speed was eratic and got allot of powder fouling. I assumed this was because I wasn't burning over 68.5 effectively with my barrel length. 67-68.5 gave me less than .2 of vertical on a 600 yard ladder test. I then shot an ocw test at 100 and found 67.6 to be in the middle of a node. I then shot different COL's with 67.6 and determined that they shot best kissing the lands. My chrono still reads 2885-2904 at 15' from the muzzle with a e.s. of 19 and sd of 9, so I am very happy with the load even if it is slow, just trying to figure out why.
