Because of the "gap" that will be there when shooting a shorter shell....Also, I will be shooting the slugs out of a rifled slug barrel. I did find on the Lightfield slugs website under FAQ that they also state that you shouldnt shoot 2 3/4 inch slugs out of a gun that is chambered for 3 1/2 inch. But 3 inch would be "ok". I'm just alittle confused.
You want to know why Lightfield councils the use of 3.5" slugs? Because they make a heck of a lot more money off them. The production cost difference between 2.75" and 3.5" slugs is a few pennies per shell, but they'll cost you a little over $3 a box more for a box of five, 3.5", Lightfield slugs.
I'd challenge Lightfield to produce pressure test results demonstrating any significant pressure differences between 2.75" shells fired in 2.75", 3" and 3.5" chambers. In fact, I'd wager that, despite the "gap" issue, the peak pressures with the longer chambers will actually be LOWER because of the extra freebore length. Again, I wouldn't sweat it. If you're going to shoot sabot slugs in a rifled barrel, the sabot is plastic and will easily give way long before pressure becomes a problem. The worst side effect you MIGHT see from shooting 2.75" slugs might be less than optimal accuracy. Otherwise, they are perfectly safe.
