Thread: Bullet seating depth and OAL issues

Ok, I'm with you now.
Saami (I think that's spelt right) is a measurement to fit all rifles. The people that publish data don't know where your lands are.
Ok, Barnes recommend 50 thou jump.
The powder data oal, will be saami data. You don't really need this, and it confuses the situation because you know where your lands are.
The die set is probably saami as well, don't worry about that either.

Start again, here is what I suggest.
Take a lands measurement. (Touching) Wright that down.
I normally start from ten thou jump to the lands. And during testing seat deeper, if I have no joy. It's safer than starting deep and seating back out, most people wouldn't do that.
If you want to you could start at your 50 thou jump. Whatever you do because your new at it make a dummy round and make sure it fits and feeds in the mag. Also chamber it and carefully extract it. Make sure it does chamber. And check to see there are no marks on the projectile. Which means you do actually have jump, the lands haven't scratched marks on the projectile. Color it with a pen if you like.
From there start loading from min to max. (Check other things like case length, and keep an eye on pressure signs)

Hope that makes sense and helps, good luck.
