Not much kick involved in a normal HW 55 at 8 plus pounds. 10M shooters wear a stiff shooting jacket, feels and looks like a straight jacket, a fact not to be lost on us...LOL. It is padded with non slip areas and one puts ones elbo into your side, forming a triangle, The hand forming a fist for the gun to rest on in some cases.... a short front mounted sling forms a loop around that elbo. Barrels move and the mass of the heavy sleeve damps that movement, slows it and is not "pulled" by the trigger as easily. Remember they are all near perfect shooters and need every legal aid. They are very barrel heavy but the jacket holds you in place. They can feel very awkward to the beginner....like me.
Now for fun plinking they are too heavy and much more fun sleeveless or with the lighter sleeves for can poping. I have found a Walther LG 55 DT Tyroloean with no sleeve, made that way, that may be the ultimate plinker. will post when it is all back together.
