Re: Low Recoil 308 loads, need help
Another vote for the Limbsaver.
I have them on all my hunting arms (12ga 870 slug gun, .44Mag M94 Carbine, .30-'06 M70 featherweight), and even on my M700 VLS .223 (to add LOP). They reduce recoil to the point where confidence is restored and practice is not a chore.
Going for 1000yd with a .308, the proper approach is to use the 175SMK with an appropriate load, then work on reducing the <span style="font-style: italic">felt</span> recoil.
In addition to the Limbsaver, strategies which increase the working mass of the firearm make better sense than trying to wimp down the load. The .308 won't tolerate such tactics and still shoot well to 1000yd.
Using the Lead Sled (or something similar) approach has merit, and also has the advantage of allowing the mass to be gradually reduced, acclimating the shooter to recoil in small increments. Eventually, she'll benefit from that.
From working with youth, I also find that hearing protection makes a difference in perceived recoil; all that noise can also instill a flinch. Youngsters will react even to the noise of a .22. Muzzle brakes may help, but this is one area where they can be counterproductive unless really good hearing protection is employed.
