[QUOTE="dog caller, post: 101735, member: 5659"] [ QUOTE ] With Varget, the max with 85 grain bullets in the .243 win is around 38 to 38.5 grains (depending on whose data you're looking at) [/ QUOTE ] Dan, Barnes manual #3 lists the maximum charge weight for a coated X bullet at 39 grains of Varget. They don't list a Varget load for the regular X bullet. Other powders that are listed for both the XLC (coated) and XBT (non-coated) show that the maximum is always two grains more for the XLC. Knowing this and knowing that Barnes suggests the TSX can handle one or two more grains than the regular XBT, I deduced that a safe starting load for the TSX would be about the same as for the film coated XLC X's.

None of these shot particularly well but showed [i]no[/i] signs of pressure. After joining here and reading about the Ladder and OCW tests, I thought I would give the combination another try. Since I showed no pressure signs at 39 grains, I just started there to begin the OCW test. [ QUOTE ] It might be that you're too high with the powder charge. Did you have any pressure signs?

[ QUOTE ] One more question: What rifle are you using, and what barrel length? [/ QUOTE ] It is a 22 inch Savage 16FLSS with a 1 in 10" twist. Also, all rounds were shot over a Prochrono Digital chronograph set 10 feet downrange from the muzzle. Thanks, Dan, for taking the time to help me with this.
