Make shotgun into a rifle - Remington 23inch CL 870 Express Barrel Fully Rifled

There is a area I hunt that states you must use a shotgun with slugs. I have shot numerous deer with rifled slugs, but they are only good for about 100 yards. I have seen many at longer distances and had to pass them up. This rifled barrel with a shotgun scope will make that possible. It took me 15 shells to sight it in. It is very accurate. Grouping about 2" at 100 yards. I use Hornady SST 2 3/4" Sabot shells. Hold it tight to your shoulder and make sure you have a scope with good eye relief. I am almost 80 and was able to shoot 15 of them and not be all shaky.
