Before my wife went to shoot her red deer, I took her out a few times shooting feral goats,with the 708 she was going to use on deer, however I loaded a mild load with 120 gr NBT, It had enough to flatten a goat at 300 yrds but mild enough that it didnt frighten her nor beat the crap out of her either, shes only little too.
When it came to the deer hunt, she carried rifle I carried magazine and ammo, rather stout load pushing a 140gr NBT, because of the added adreline and focus of the "HUNT" she paid no attention to what ammo she had, or the added recoil etc.
Concentrated on getting the job done, and she did! first deer at 240 yrds, not along way but I know plenty of men that have cocked up shots half the distance.
So what Im getting at, do a mild load with say a 120 gr V max or similar for pratice and getting used to the feel of the rifle ,then move her into the full blown hunting load.
BTW I never told her, oops
Just another option for you to consider.
