I don't think either have enough power for slugs unless you Modify them , I had 2 impacts in 30 and I have a wildcat ,I think for $1300 the wildcat is a better buy ,
I love wildcat to carry it is light and quick to shoulder ,I am not a fan of the impact for .30 caliber , even the .25 cal does not have the power it needs for heavy slugs I have not tried the latest regulators maybe they will give it a boost ,
I am not sure of power of the wildcat in 30 cal , I seriously think it will be under powered ,especially with slugs ,unless it gets modded
I had same issues with .30 impact it was great with pellets but no power for slugs . but even with pellets gun had to be maxed and could of used more power
You are basically paying extra for more shot count , bigger magazines .
what do you plan on doing with either gun ? like if it was a hunting gun in thick stuff id get wildcat , if i needed 100 shots per fill Id get impact
I like the wildcat in 22 only and crown and impact same
