1. G1 .357 BC for 100 TTSX.
2. G1 .400 BC for 101 LRX
3. Both are designed to work in an industry standard 1:10" twist.

I'm still working with them out of both my Bob's. One a very custom Pre64 action which will allow me to seat out further. COAL of 2.960" when ogive is touching throat. As suggested by Barnes I start at .050" off the lands for a COAL of 2.910'. Other rifle is a Montana 84M. I can seat at 2.957" with the ogive touching the lands; 2.907" puts me .050" of the lands. BUT the mag length forces me to seat to 2.835" to reliably feed from the mag which means I'm .122" off the lands. I'm not worried about that since Barnes 100% copper bullets can shoot great when say off the lands. Jury is still out. Hoping to pick up where I left off. My new 21st Century expander mandrels are enroute and now that hunting season is over for me, i'll start up a project with IMR 4451, the same powder Mule Deer says he gets little groups with in his latest article about cartridge neck lengths.
