I will tell you with mine that if you were shooting 45 colt then switched to 454 then you probly got it real dirty and you should never switch from small to larger cases without cleaning.Extreme pressure will result as the lead builds on the cylinder where the lil ramp is and creates serious pressure issues as the bullet is allready in contact with the lead build up.
I have noticed this same thing with mine ,push the cartridge extracter out and there is prolly some biuld up under it clean it out and the rest of gun and should be fine.

one more thing..the 454 takes small rifle primers not pistol primers.... factories do make mistakes...i just saw a lot of winchester 300 short mags that were blowing out primers. buddy called it in and sure enough there was a recall on that lot number...they were smokin hot.
