  • My Remington 700 ADL 30-06, the 150 grain SST is set just above the cannelure (shorter than recommended OAL) and its shooting dime size groups.

  • I also suggested that Hornady's 7x57 LM load (139-grain SST at 2830 fps) could be safely improved to 2900-2950 fps (or higher) with the same 139-grain bullet in a 24 barrel, and pointed out that a number of modern day handloading manuals do just that.
