Since I hand load, what I'm going to try to do is try to build a load that gives me zero @ 100 yards with the sights as they are.
If I can't go that low with the powders I have on hand I'm going to try to emulate the 'torped' loads so the brass disk info will be correct. With mine the disk says '1' so that's 3.5"high @100 meters.
I'm going to buy dies this weekend and I have some Hornady 140.0gr on the way. They're flat base but should work OK. I've had great success with Hornady bullets in other calibers lately so I'm sticking with them.
I'll make sure to post back with results.
I have a few old imperial 160gr that I'm going to run over the chrony in the mean time next time I go to the range just for reference of what the factory loads do.
I think tailoring a load to suit the sights might be more fun than changing them, that could just be me though.
I hope I'm not hijacking the thread, just want to add! I love the old 6.5,just haven't toyed with it in years.
