not sure if the .355 bore using a .357 bullet is going to be an issue so bullet selection I feel is a moot point.Winchester really just reintroduced the old 351SL but rimless and a bit longer .The 357 max I do like in my modified 1910 win and a mate for my DW .

The rimless case with the body taper should not be an issue unless people get carried away with oversizing the case ,just my opinion as there are numerous straight wall semi auto pistols and carbines on the market that seem to run
