The slip fit design is great but you have to fire a squib load first in order to hold bullets in barrel that is a pain in the ... if you clean your rifle every night after a hunt because the next morning you have to dirty up the barrel again this is no problem if firing a cap at say 3 or 4 am before you get to your hunting spot otherwise sabots you can load and keep loaded if you want to risk rusting barrel if moisture gets in there so some considerations to make ? But it will be a great rifle once you dial her in !
