Is there one reasonably priced bullet that I can use for both 9mm parabellum and 357 Sig? Purpose is punching holes in targets. I prefer factory loads for carry purposes. After a bunch of searching here and elsewhere, it sounds like I need a flat-nosed bullet for 357 Sig. Glock 26 & KelTec PF-9 (9mm) and H&K compact (Sig 357) so lead bullets are out. Hornady makes a 124 grain "encapsulated" flat nose. Rainier makes a 124 grain "plated" flat nose. Please let me know if it makes more sense to use a separate 115 grain round nose for 9mm. Thanks in advance for advice.
