I’m going to see how the recoil is with the billets I picked at around 1800 FPS. If it’s not bad then I’ll have her practice with what she’ll hunt with. other wise I’ll work it down.I second the lighter load for practice and separate for hunting. My oldest two kids both practiced with a 22 until they pulled the trigger on a 243/270 on their first deer at 8. Since then, they've both went on to practice with a 243 and 270 without issues and have killed a few deer since. My youngest now 8 is practicing with a 243 w/o issue after watching the older ones.
My 11yo son drew a muzzy elk tag in NM this year so he's going to start getting some muzzy experience. I haven't worked up any loads just yet though, but may do some lighter for practice or just let him shoot standard loads from the lead sled.
