to say 708, 308, with pistol bullets and the SEAFIRE BD loads and you will be in business.

I gave a friend a slight modification of his loads for her small recoil "SENSITIVE" son and the deer wnt less than 35 yaRDS AFTER A 110 GAIN 30 CALIBER RNSP went through the proper plumbing.
357 Mag/Max in the Handi oughta work also!

Start with MANY low noise, low recoiling practice rounds and with the time till season opens she can shoot most anything.
Good quality EAR PROTECTION is a MUST to get a new shooter acclimated to shooting.
