There are very few people in this world that I know that can hand me a box of reloads that I will actually shoot.
May sound a little anal, but it's the truth.
I'm assuming:
1. You know the guy really really really well
2. You know for a fact that he knows how to reload ammo correctly
3. You trust that he reloaded that batch without distractions and without incorrect data
Personally, I'd at least pull a few to check the charge weight and consistency. Even then I'd use caution when shooting them.
Also, if you can tell us what the bullet weight is, some of us can cross reference it with load data from a trusted source to see where it falls on the charge level (i.e. - light charge, medium, heavy, max load, etc.)
