Like others advised / Hodgdon is making Winchester powders now .....so I would use their data. Between Hodgdon's / Rainiers data ... what they are suggesting is 3.7 Min / 4.5 Max .......

Its your gun / your eyes, your hands ...... but most everyone on here responding to you has suggest you start at the Min / not the Max ....

I would recommend you drop it to 3.7 gr / load 3 or 4 shells at 3.7 / same at 3.8 and a few more at 3.9 / a few more at 4.0 / and last, a few more at 4.1 --- and test fire them for accuracy and how they cycle the gun. I would not go past the mid-point of 4.1 for any reason ( but that is if it was my guns, my eyes and my hands ...)...

By the way, for test firing -- I would only put 2 rounds in a mag - then fire 1 round at a time ....make sure the slide seated properly with the 2nd round / then clear the round from the chamber by racking the slide. Then repeat / 2 rds in mag / firing 1 round at a time. Then check for accuracy....
