resizing 6.5 grendel to .243 LBC

[hydrotech]

Wolverine,

can you shoot heavy 6mm VLD's with that .243 LBC? like over 107 to 108 grains? and also, How do you know when you are .070 (thats 70 thousandths right) from the bottom? why cant you run it all the way through the die? I am guessing that would bump the shoulders at the top of the case back? thanks, i have only been reloading a few months.

Myself and a buddy are the ones that designed the 243LBC. I have a 6x45, and love it, but wanted more speed, was thinking 6PPC, then decided on more case capacity and decided to lengthen the PPC 70 thousandths, and use necked down Grendel brass with 6PPC dies.

I had never even heard the name Robert Whitley, until the first discussion with our reamer manufacture, he brought up his name, and that he was doing something similar. Mr. Whitley has done some awesome work. and has probably forgotten more about wildcatting than I know.

I did not do this to compete with anyone, I did this because I wanted one, and it has kinda taken on a life of it's own.

I am not sure where the 85gr at 2800fps came from, but I am getting over 2800fps with a 100gr Partition out of a 20'' barrel that has to be loaded to 2.195 OAL because we designed the 243LBC with a VLD chamber. I am getting no pressure signs, and have plenty of case capacity left to work up more speed, but the accuracy is so good, I have not tried for more speed yet.

Hydeotech, you do run the case all the way into the 6PPC die, it is full length resizing all but the last 70 thousandths of the case at the web which is the strongest part of the case. One of BHW Prostaff has 12 reloads on Lapua brass and has had no problems, that same Prostaffer is getting 2965fps with a 95gr VLD out of a 20'' barrel.
