Hi......I'm wanting to try some 150gr. TSX bullets in my old Savage model 99 lever action rifle and being this is an older caliber not much load data is available. I'm planning on using IMR 4064 powder which is pretty standard for this caliber but my concerns is C.O.L. the 300 Savage has a such a short neck 3 of the grooves on the TSX bullet is going to be exposed after seating to a shoot-able overall length (2.550"). Is that ok? unlike the 30-30 cartridge where the grooves are totally inside the long neck of that round it just looks odd on the short neck 300 savage case. Anyone have any experience with these bullets in short neck cases like 300 savage.
