I have no experience with slug. Never shot them due to the price being so high vs pellets. But I want to try it out. So my question is, is 600mm or 700mm better for slug? I've seen everyone who shoots slugs are using 700mm. Is 700mm necessary? I have the 600mm 25 cal impact. I choose 600mm over 700mm cause its more compact, easier to carry around without worry out bumping the barrel, also dont have to take off the LDC everytime I put it back in the case. So if I want to shoot slugs accurately. Should I just buy the slug liner 600mm. Or buy the whole 700mm kit? I want the best accuracy possible from my impact. Like 1/2 inch at 100 yards.
