Every time I or someone else shoots my 7/08 I wonder whyothers think they don't kick.I shoot every week with calibers from 223 to 300 wsm and I can notice my 7/08 kicks pretty good.
Any time you can soften the load for a young shooter thats starting out they are going to injoy it more and stay with it longer.The load you came up with should work on deer fine.
I let a friends grand daughter shoot my 7/08 and 260 the other day with the 260 she put 3 shots into a one inch circle,after shooting the 7/08 a couple times she didn't want to shoot it any more.She is 15 yr old.
Hope your daughter gets a big one.
