My wife is only about 5' 4" and petite. She shoots a Winchester Sporter .300, which is a bit lighter than a Sendero.
Before we ever took that thing to the range, we put a gel filled recoil pad (made by KICK EEZ
www.kickeez.net ) and a muzzle break on it. I ran a couple of my hotter handloads through it and was very happy with the results.
I have a video of her shooting her first shots with the gun. There is very little muzzle climb and she never complains about going to the range.
Hope this helps.
