Honestly, I never understand the "quickie" mindset.
Even when running my Dillon 650 progressive press, I am fastidious about details. When you factor in the time to assemble your reloads, the time to drive to the range, clean up, prep work for your nest loading, not to mention the cost of components,
why not just use the right bullet? Isn't worth it just to get decent, tight groups?
Heck, I often don't mix ammo for firearms of the same cartridge! Properly label this batch of .38 for one revolver, label another batch for another. The difference might just be the weight of the bullet or (more likely) a .001" difference in cast bullet diameter.
For me, it makes a difference. For others, I will acquiesce, it might sound like a waste of time.
For years, I labored under the commonly assumed nonsense that "for 44 mag or 44 special, you use .429" jacketed or .430" for lead". Turns out, most of the 44s I've used need .432" +/- .001" to get their best results on target. (Not to mention alleviating the leading clean up headache once I got home!).
Once I did that, I happily kissed 44 cal jacketed bullets Bye-Bye!
Elsewhere on this forum, a member is looking into obtaining and fitting a new cylinder for his S&W 1917 because the throats are oversize. Turns out he already owns a mold for 45. The easy solution to his woes is to use a different alloy so he drops slugs of the right diameter. If buying a second mold is too much of a hassle or expense, "why oh why" would getting/fitting a second cylinder make sense?
But, I digress....
Best Regards and Sincere Respect,
Jim
