Are you using Rifle Primers?
They are stronger than other primers.

If you are shooting a lot of shorts, ie 38s in a model 40 or 44 mags in a 445, you could be getting a carbon ring in the chamber from the shorts that us preventing the full size SM cartridges from fully seating into the chamber. If they are a bit proud, the case head will protrude and drag on the recoil shield and cause issues similar to what is described.
ÂÂ
A good cleaning with a brass brush in a drill and some solvent (non flamable kind) will remove that ring. ÂÂ
Anything worth doing is worth doing well.

If a man designed it, and a man built it, then a man can fix it.

Exactly what I did before the shoot because I was shooting 44S and 44Ms.  This was 2nd shoot since acquiring it.
I think I need to take it apart and polish/sand the firing pin as it has a slight mushroom on the tip.  Do I sand back to a fine point?  or make sure the tip is flat?

 Am I wrong thinking the firing pin head is rounded?

I think you're correct in thinking it is a smooth radius, a point would pierce the primer,YIKES!!!!!!!

Yeah, piercing the primer would probably create a bad day.

Could be primers, there is some difference in hardness between brands. Can't offer suggestions on brand as I've been out of the game for ages.
