I just received some 357 max brass I ordered and was going through some load data using 175gr through 200 gr cast. Several powders recommend using CCI450 small mag rifle primers. I understand the use of small rifle primers due to the generated pressures, but I have approx 2000 winchester standard small rifle primers. and was wondering if there would be a concern using them in place of the mag primers. Not all the load used mag primers though. More towards the heaver boolit weights using 2400,Rl7 and h4227.. I will be sending my 12" T/C 357 mag bbl to Bellm for rechambering to 357 max.
Thanks for the help
