We can theorize about hypotheticals all day long, but magazine fed, semi-auto rifles and/or pistols seems to be the weapon of choice for spree killers. Whether or not they could be as effective with a pump action shotgun, single action revolver, bolt action rifle, or any other such non-ban item is immaterial, because these are not the weapons spree killers prefer. I expect the body count would have been lower with a weapon that has a slower rate of fire due to not being magazine fed. Spree killing would still be possible, but perhaps not as severe. It's hard to imagine someone with a pump shotgun killing dozens of people before they can flee if they have to perform a cumbersome reload every 6-8 rounds.
