My thought is I trust my hand loads but for SD I prefer factory ammo.
(and I always shoot a box out of the lot I am going to use)
That way in case I ever needed to use it, nothing could be brought up about using special "killer" hand loads.
Distance to target could be established if necessary, etc.
Should it make a difference, no, but if it might it's not worth the risk.
Lots of different feelings on this, but that's my take.
off thread but
wrench459, not the saw, the BFG9000.
I remember (years ago) the pink monsters used to scare my 6 year old niece to death (had to leave the computer and the room and come get me) until she found the saw and could saw them, then she was good to go.
The pistol was tough when deal with the pink monsters,shotgun was better, but the saw was best
