I'm not sure if you're serious in your posts or not.
We're not talking SWC's for conceal carry...we're talking SWC's for practice and target shooting.
I carry hollow points or frangibles in my conceal carry guns.
When people spend a lot of money on a firearm for accuracy, they tend to want to shoot the most accurate load possible...and shoot a lot of it.
In competition, that extra tight group will earn you more points...1/2" can move your round into a lesser scoring ring.
I handload 185 and 200 grain SWC's for less than a dime a round.
That means I shoot a LOT, so when it comes time to shoot 230 grains, I shoot it VERY well.
It also means that should I need to use my CCW, I'll have more confidence in my shooting and accuracy as result of shooting tens of thousands of rounds of ammo of ALL sizes and shapes for the last two and a half decades.
I DO reload, and have reloaded tens and tens of thousands of rounds of 38/357, 41 mag, 44 mag, 9mm, 45 ACP in the last 26 years...since I was about 20 years old.
I have loaded RN's, SWC's, WC's, hollow points, cowboy loads, etc., and I always keep an open mind to what ballastic experts have to say about bullet choice.
I don't handload a bullet because other people do it, I handload various bullets to find out the best accuracy, recoil, and simply because its fun.
I also handload a tremendous number of 230 grain, but I'm one of those people who believe in having choices, and not having other people dictate what is the only ammo I should shoot.
Firearms manufacturers are designing semi-autos with a larger throat just so they feed various types of bullets.
It's pretty obvious you're new to shooting if this is only the second forum you've ever seen SWC's discussed...and it's obvious you're new to shooting if you think handloaded 357 rounds didn't work because they are made "cheap."
Instead, I'll tell you I've loaded tens of thousands of 38/357 with no problems, as revolver cartridges are pretty idiot proof.
Maybe the fact that you bought the bullets "cheap" is an indication of why you had problems.
Once again, do a Google search on .45acp swc and see how prevalent it is.
Not sure what your analogy on the dune buggy truck thing was, as many pistols are designed by the manufacturer from the ground up to shoot SWC's...your truck wasn't.
Try taking up handloading before you enter into a discussion on handloading, by the way.
