All I can say about that subject is OUCH...I was at a friend's house to sight in my Ultra Slugger and he asked me to run a couple boxes of ammo through his slug gun to check his sight zero. He has a Mossberg 695 bolt action slug gun and a Eotech holographic sight mounted on it. He handed me two boxes of Winchester Partition Gold sabot slugs to shoot. While walking back to his shooting range in his backyard, I took note of how light the Mossberg was...At this time I did not correlate the light weight shotgun with the high speed sabots that he wanted me to shoot. Well, when I pulled the trigger for the first time, I made the connection right quick...OUCH. I have never been kicked so hard by a shotgun...I ended up dialing in his slugger but I vowed to never shoot that beast again...He can have it. I sighted in my Ultra Slugger right after the Mossberg and what a dream that was. I shoot Lightfield Hybreds and my slugger does not kick half as bad as my buddies. The combination of a heavy slugger with a slower speed round is the combo that I am going to stick with...
I learned my lesson...and it still stings.
