Never had a problem with loads for my balckhawk and Henry 357 match up. I mean one load would tend to be more accurate on one or the other but they'd all cycle fine in the henry.Its not always easy getting a load for both platforms. Because of bullet ogive.
Same with my 629 and ruger 44 carbine.
I mean....this really isn't a problem......if I seat them a tad lower to cycle right in the winchester it won't effect functioning in the 629.
