Women around the world have successfully used much larger calibre rifles, .375H&H as well as some of the .458's. They must have indeed had copious amounts of training and practise.
: There are no women in my family who would be able to handle such a rifle. My wife shrunk from the recoil of her .375 Winchester Big Bore 94, so I now own it. Nice rifle with 2 mose to it's credit now. My younger daughter, at age 24 and 160 pounds likes her .260 Rem. She's shooting 160gr. RN Sierras at 2,300fps and finds it pleasant to shoot. She's yet to fire her 300th round, but can hold 1-1/2" at 100 meters (8 out of 10) shooting off her elbows. this is better than a lot of guys do off the bench. The stray 2 rounds opened her group to 2-1/4". I'm not sure I could do better right now of my elbows.
: Most women are about peaked with .270's, .30/06's, etc. and are much better off with a good 7mm Mauser.
: With good bullets of sufficient length, there is little they (6.5 or 7mm) cannot kill.
: I think a 9.3, of sufficient weight, started with 232gr. bullet at 2,000fps, then worked up in power and bullet weight, might be handled by a women after some years of practise. A standing bench would be most helpful - the type used for regulating & shooting heavy double rifles. that way, the body can bend at the waist and help absorb recoil.
: My .375/06IMP, shooting only 56gr. H4895, and developing 2,470fps to a 300 gr. bullet is beyond most women and many men (average) for that matter. It's 8 1/2 pounds comes back pretty sharply, considering it puts out the same speed as most 30gr. .375H&H factory ammo. I feel it's recoil is less than most .30 magnums, though - not as sharp. For those who shoot heavier recoiling guns without any flinching, this, of course, is not aimed at you. It is a general statement only, so there is no need to jump on the 'protection wagon' and declare how heavy a gun you shoot without flinching. Too - many guys can shoot without ever flinching at the bench, but many cannot do the same from the standing postion, where they should be practising, but don't.
