I have to admit, I couldn't fool my daughter for very long. After about her third deer with that 308 she ask me about the "different" bullets & I said, well I did tell you they were lighter, 170 gr cast vs 150 gr Hornady but I didn't say they kicked less.
She said I noticed that they kicked more but it didn't matter, by then she was a very good shot & her confidence in that gun & load was very high. From the sitting position with a sling she was & is deadly.
