Indeed it is IMO , and if your so inclined it can handle higher pressure loads than the marlins , it's debatable if it's needed and still won't turn it into a 300 yd ctg but it does give one that option To load to "+p levels" Neither me or the deer I've killed with it knew the difference between a Rem factory corlock or the couple times I've loaded beyond book max . So I load for accuracy as my main goal these days with cast .
