I don't understand why the difference between kids deer gun and a grown man deer gun.
I pack my 6mm Remington more than anything and have no issues killing deer.
85 grain Sierra SP has been used most in it for about 40 years and flat kills.
Some 100 grain stuff has been used, 80 grain, 95 grain, it all works without much drama.
In the 22-250 I have used all styles and they work but the best was the 60 grain Partition. Broke shoulders with no problem and was a very quick killer.
Be hard not to recommend the 6.5 CM as you can load light bullets with reduced powder for smaller or more recoil sensitive shooters all the way up to over 140 full power loads get the full potential of the round.
My buds boy started with the CM and 100 grain Barnes, been killing with it for about 10 years now and won't even entertain the idea of a different cartridge or bullet.
