This post is actually on topic, but it might not seem that way at first, so just hang in there.
When my wife fired a handgun for the first time in her life (at a Florida indoor range), the availble rental handguns at the range included a number of .22s. I picked the largest, heaviest revolver of the lot that could shoot .22 shorts. I bought a box of shorts and long rifles. When she fired her first shot with the shorts, she said "that was fun and very easy. What's the big deal with recoil?". Then she fired the long rifles, which she also found fun to shoot and very low recoil. Then she fired normal-power .38 out of another heavy revolver. She said "far louder and more recoil, but still very fun to shoot". Etc., right up to .38+P out of a five-shot revolver with a 2" barrel.
My wife's experience with long guns consists of her firing our now useless 7.62x39-caliber semi-auto. That gun has an adjustable stock. She found that rifle very pleasant to shoot and she was extremely accurate with it.
Neither she nor I have ever shot a long gun that does not have a butt stock. She has never fired a shotgun, but I have shot some clays with a 12ga O/U in my youth.
Now back on topic. I'm seriously considering buying a 12ga(!) Shockwave for my wife and I want her first shot with that gun to be as close as possible to the experience she had shooting that .22 in Florida, which I know is impossible, but you get my drift.
Before she fires the shockwave, I intend to wrap the grip with hockey-stick tape, and maybe even the pump. I'd like to install one of those recoil straps on the grip, too.
My question is simple. Which 12ga ammo has the absolute least possilbe recoil? BTW, if we buy a Shockwave, I intend to install an Op sol mini-clip and shorty's will probably be the only ammo we ever shoot. Of the shorty shells, which has the absolute least recoil?
If you have any other suggestions in this situation, I'd appreceiate reading them. I've seen several Shockwave videos which demonstrate various firing positions, but I'd like to hear suggestions on the best position for her first shot. I'm not concerned about her accuracy. I just want her to experience the recoil without being put off by it to the point where she does not want to fire it again.
Thanks.
