As a 357 maximum owner I can tell you your not missing out on anything with this bore size nonsense. There isn’t a single .357 bullet in production that is actually suitable for the impact velocities you can achieve with a 350 legend. Not a single one. The closest one will probably be the 180 xtp which is popular in 357 max. This is what happens when you push that bullet to 1990 fps muzzle velocity. The one on the left was shot into water jugs at 20 feet, the two on the right at 100 yards. Still over expanding at 100 yards. This is already downloaded. My 13" 357 max will push them 2200 fps if you really push the pedal.

Now sure if you are just plinking or shooting varmints or something then go ahead and use handgun bullets, but this is really only a benefit if you happen to have a pile of revolver bullets.
The story is not a whole lot better on the .358 side of things. Have you looked at what is actually available in .358 bullets and what the prices are? Almost all .358 bullets are $40 per 100 or more. You really want that??? Plus most of them are too heavy for the 350 legends small case size. 180 is ideal, 200 is starting to push it. Most of them are also too hard to expand decently at the velocities your going to push with this cartridge. The one and only bullet in .358 that is actually appealing at all is the 180 grain speer hot core. Your going to want to push it at least 2200 fps to make sure it will still expand to 200 yards but it would work.
So where are all these bullets that people are just dying to load in there 357 AR Max that they never bought or cared about? What do you think your missing out on? Why can't you buy one of the bullets on sale now that was actually made for the 350 legend? Please explain it to me.[/QUOTE
