What this is called is "blowby" it is more common with revolvers that do not have the ammo matched to the cylinder chambers. In other words the bullet is say a .452 Dia with a chamber of .4545 in a Colt SAA 45 caliber for example. this allows "blowby" in the chambers. The other reason in a pistol is that the powder charge is too low for the bullet to obturate.
Since you are using a rifle, the possible reasons could be
1. the headspace
2. chamber was cut incorrect.
You could cerrosafe the barrel to tell you more,, or you could size a piece of brass, then place it in the chamber. try to feel for the tension. then begin to place a piece of paper between the brass and the bolt face. This will begin to tell you about the headspace. One piece of paper is good since you want a couple of thousands for the headspace. but if correct length, sized, brass is allowing say,,, 6 thickness of paper then headspace is wrong.
BTW just try to tape a piece of paper with cellophane tape, go slow so that you do not twist the tape off.
The load sounds good. You do not need to use magnum primers with that powder.
