Redhawk, I think you will be fine. That 444 case is very stout. I would suggest making sure there is no lub on the cases and the chamber is free of any oil, grease or lub. I have some wooded q-tips that I swab the chambers with acetone to remove any of this. From what I have heard the 444 case is so strong it will compensate for excessive pressures. You just need to do you part and make sure the chamber is clean and dry, to reduce rearward thrust.
I'm sure someone else will chime in. Good luck, jh
