7 mag is just that a magnum with a lot more powder. Like phool said the 7mm-08 is a necked down 308 case using a 284 cal bullet. You get a better bc and it is a very flat shooting round as well, with little recoil.243 will kill anything, good shot placement and a good bullet is all one needs. Heck there is a young lady that just put a moose down with one shot from a 243. I know of one rez hunter that shot probably 100 elk and deer with a 243. Never had any problems with killing power. I do like the bullet choice on the 7mm over the 243. You can get into some heavy bullets for the 7mm and really work them well with some handloads.
Yep what ever floats your boat
You guys keep throwing out calibers. With my 9 year old it was not about the caliber it is about what was weighted appropriatley and the ability to hold the gun up with proper stock length and barrel heavy variations.I had over 12 different "models" in her hands and two stood out dramatically...the tikka t3 (whatever caliber floats your boat) and the youth model 700 (again whatever your ego tells you on caliber). Now this is for her size at 9 yrs old, her arm length, her strength etc...So get your kid in a bunch of gun stores and find the best fitting "model". You all try on boots before you buy don't ya?
