Nope I aint 12 and 70 pounds. But my daughter was 12 and around 70 pounds just 8 years ago. And at 12 she was shooting my .270!!! The recoil of a 7mm.08 is nowhere NEAR 40 to 50% more than a .243 I know because I HAVE one. I dont have to compare it on paper. As I said TWICE now, recoil suppression technology reduces FELT recoil. Im not a young wippersnapper myself and Id just about bet my knowledge of firearms is well within your range as I was trained by some of the best in the world (marine scout/snipers) and do know just a smidge about this subject. Felt recoil verses true recoil is 2 completely different worlds. Its like comparing a single shot to an Auto loader. Which ones gonna kick the hardest? You have suppression in different ways, I.E. An auto loader will take a good bit of the recoil. Then you have Gun Weight, then Recoil absorbtion in kick pads. Many ways to lessen the Felt blow of recoil. At the chamber is where they come up with all this data that people read and think because it says it in a reputable magazine then it must be gospel. But that aint the facts here. Yes if you put up 2 identical rifles, one chambered in .243 and the other in 7mm.08 then yes there is a small difference. Now you take that 7mm.08 and put a kick pad on it then put it on a kick scale and see what you get in the difference. Its FELT recoil that is the killer and it is easily reduced. A .243 is a wonderful calibre for deer but say in a year or 2 PoPs wants to take her on an Elk hunt. You think he is going to want to have her out for a Bull Elk with a .243? It would kill it with the right bullet but it would sure be undergunned. Now say he got her the 7mm.08...Load that puppy up with some 145's and go wailing!!!
Ironwood you completely missed my point as far as using REDUCING technology so that the 7mm.08 would be a viable and more productive chambering. While yes I do love the .243 for kids, as All mine started with, the 7mm.08 is a more viable and powerful round. With todays recoil suppression there is just no need to limit her to the smaller .243 when there is a better choice! Its that simple. And as far as you thinking I havnt shot something big sir. Try on the M107 Barret .50cal then come talk to me about KICK!! Or even better, Come take my Mossburg 500 pumper with a deer slayer barrel on it and 3 inch lightfields and sight it in for me. I'll bet your shoulder will WISHING it had the same stock my .300 win mag has on it.
