I have really been trying to absorb as much 10mm knowledge as possible. Here is my dilema and some questions.... My wife likes autos and will be getting her carry permit soon enough. I carry a 3" Ruger SP101 357 Magnum. It is awesome and even put two deer on our table this past winter. I have been looking to get out of revolvers and into Glocks in favor of their ease of carry, faster reloads, and ESPECIALLY their utilitarian ugliness. I am also about to start reloading. I was thinking of trading around and getting a G29 for each of us so that I'd only be loading one caliber for two guns. I like to use ONE gun for everything....hence deer hunting with my SP101. (yes legal here) She has shot my sp101 with full power loads and can tolerate the recoil getting a nice group....but doesn't like it. Question 1. Can I shoot lead at near full power exclusively in a factory barrel? Some say that the hexagonal rifling isn't good for lead. I plan on trying to settle on a 200 gr bullet at 1200 ish fps....maybe less. I might even settle on a 180 gr cast bullet. Is that attainable or even reasonable in a short barrel G29? This will be for my personal gun for all uses Question 2. What is a good load with very mild recoil...similar to a 40 S&W load with the same bullet? 800-900 fps?? Something that she could shoot well and feel comfortable enough to want to practice with. 10mm performance is not the goal here. Just having one type of brass, one caliber, and hopefully the same lead.....I am a simple kind of man. Queston 3. If I were to buy an aftermarket barrel, which is better? Lone Wolf, KKM, Storm Lake???? Question 4. What lb recoil spring would be most appropriate for Shooting 180-200gr lead 1100-1200 fps. Question 5. If I decided to use a 135-150 ish lead bullet for her, what would be a good ballpark velocity to get her to 40 caliber type recoil?... Thanks in advance for advice. I am glad to have a wife that loves to shoot. The last time out, she had shot 30-40 rds of 38 specials when I asked her if she'd try magnums....She shot a cylinder full of magnums with exactly the same group size as the 38's with no flinches.
