I’ve been told the REAL can come off of the charge. Not sure about that. Maybe it depends on the lube used?
Some paper wadding can be compressed on top of any lead conical to keep it from coming off the powder charge.
The important thing to be aware that just about any lead conical can come off the powder charge after it's been rammed and engraved.
It's not as much of an issue at the shooting range IF the barrel is kept upright after the conical is loaded.
But anyone who hunts with a conical should seriously consider firmly compressing some paper wadding over it to make sure that it stays on the powder charge.
Some conicals will fit tighter than others, especially sabots because they fit so tight to begin with.
But after a soft lead conical gets engraved, there's always the possibility that it could move off of the powder charge.
It should be a common practice to compress some paper over it just like with a load of shotgun pellets or buckshot.
IMO the compressed paper won't change the point of impact much if at all, and if anyone thinks that it would, then they should be range testing using the same loading method that they're going to be hunting with.
I sincerely hope that most everyone would consider compressing some wadding over their lead conicals, and be sure to make it tight enough to hold the conical in place during all of the bumps and rough handling of an entire deer season if needed.
The position of the conical can be rechecked during that time, but using compressed paper wadding or a similar method really should be a common practice.
