I'd be curious to know the difference on felt recoil between the 6.5x55 compared to the 7mm-08
with the same bullet weight.
Since you are in the Yukon, and animals are large and potentially want to eat you; i would think that the .284/7-08 should be a minimum. I have a very light T3 in 30-06 that recoiled like a 300 wm with the factory hockey puck. A Limbsaver for about $55 tamed it to 243 level.
hmmmm. Lots of great advice! So get the stock fit right, get an excellent recoil pad, practice her up with light loads from field positions. As for the stock fit, is more drop at the heel advisable, in general, for women? Her 1st (and last, so far) center fire was a marlin 36 in 30-30 but she found the loading through the gate too hard for her small thumbs. She goes out grouse hunting a lot with her .22, and is an excellent shot. So is the mercury recoil reducer more of a gimmick in a situation like this?
Google 'gun fit for women' and click the link from shotgunworld. It's a pretty long article, and is geared towards shotguns, but the same principles apply to rifles. It's written by Rollin Oswald. It's the most comprehensive breakdown I've been able to find on the internet.
7-08 120 tsx loaded to 3050fps with varget/h4350 would be a good 100m elk/moose load IMO. Very mild on the range and very effective on deer sized game in the field. Stay with what you have working and adjust the load to suit, load down a bit to 2900 fps or so. I also hear very good results for the 120gr Nosler BT in the 7-08.
Keep the ranges sane and you will fill the freezer just fine with that lil 7. my 2c
