Our former sales manager Chub Eastman is in love with that cartridge. In fact he has giving african game hell with it....
He is going back in a week for another safari with it and he is writing a story for Sports Afield about it.
Nothing but great things with both the BT and Partition...
Due to contracts can't give that information out.
I can tell you it comes to us raw and we finish the brass. We can actually make this brass better and more uniform on our machines.
Then goes to our weight sorters for boxing. Every box will be weight sorted +/- .5 grain.
The BT should load for the .257 Rob.
The problem most people run in to is the ogive versus the length of the round. You don't get the proper push in a magazine and the bullet falls into the case.
