I agree that it is not a good practice to let others load for you, but if this is someone you can trust, well do what you believe is safe and right.
I use Federal #215 magnum rifle primers, but CCI #250 primers are said to be very similar in burn rates.
I also use Reloder 22 powder and 110 grain Nosler Accubond bullets. Load is 65.5 - 69.5 grains, 3298 - 3471 fps.
Trim cases to length. Seat bullets to give a long OAL for better accuracy. Just be sure they fit into your magazine and feed well.
Good shooting to you!
