have all 3 caliber impacts 30 uses quite a bit more air and around the house a bit too much out in the country if i had yote problem
or coon issue then the 30 Cal would be my choice in 600mm.
my 25 M3 600mm is my preference over .22 also 600mm barrel is good in the brush vs swinging a 700mm those imo are best for bench shooting.
slugs have come a long way in 25 imo i feel they shoot just as accurate with more wallop, in competition for points .25 they're at a disadvantage
25 makes a bigger hole than 22 so imo that's what makes the .22 more popular.
more power just as accurate bigger impact same price imo.
