Iv'e been handloading for many years.
When Iv'e loaded .308 (for my model 700) I've used a factory round for length set up, or a dummy I made from a factory round.
Iv'e misplaced both.
Iv'e tried the seat method where you run the bullet down just before it touched the rifling, using dry erase marker or soot from fire to see the lands. I never had much luck doing this. seems like a real pain.
My Speer book has a COL cartridge over all lenght spec. I got the calipers out and ran a dummy round (150 grain) 2.80". This seemed awfull long :hmmm: Foreget it when the 130gn is used, that comes up way short. :insane:
I soppose I could run the COL and mark the bullet with dry erase and try to make sure I'm not getting rifling contact, or just go .10 or .20 below COL?
What do you do?
