Thread: 7mmRM project

That's the amount of powder burnt in the barrel, surprised me that by the slower powder all burnt but it's a pretty compressed charge.

Got that length from your first post, comparator measurements are no use to Quickload it needs to be from tip to base
ADI Manual OAL is 3.290 or 83.6mm

Ok, I think I have figured it out. So those stats are based on the OAL that I provided and then ADI has taken the recommended % off, for good seating depth? So am I right in assuming that I should be able to seat them a bit further back than they are atm (85mm - well on the lands) to 83.6mm? I think thats reasonable, my first pic looks like the projectile is well in the land anyway (second opinion?).

Edit;
Excuse my lack of knowledge here...(hence why I have started this thread)

Whiteboard marker test is showing average of 83.6 CaseOAL. (Projectile pushed into case up to where land marks stop) Guessing I’m missing something? Do I back the round off by a further 10%? *confused face* or leave it?

Help much appreciated.
