175 SMK and 155 Scenar have higher BC's than the 168 SMK.
155 SMK: 0.450
168 SMK: 0.462
175 SMK: 0.496
155 Scenar: 0.508
You can drive the 155gr bullets considerably faster than the 168's and 175's too.
I'm shooting 155 SMK's at 2875fps and I still have some margin to warm up the load some more.
Once I run out of these SMK's, I'll move over to the 155 Scenars I bought a little while ago.
