In 35 years of casting and reloading, I've never seen a reason or need for powder coating bullets. Properly sized/lubed bullets of an alloy suitable for the pressure/velocity they are intended for will not lead. Just MHO.Don
Sure... it's not a need it's a benefit.
The benefit of shooting coated bullets becomes more evident the more rounds one sends downrange.
I shot lead for years and never had a leading problem but it was a lot dirtier than shooting jacketed. Not just the guns but the loading tools and the whole process. Just the benefit of cleaner mags, cleaner holsters, gloves, etc.
Everyone I know that shoots a lot has moved to coated bullets. They shoot commercial brands and they are just as clean as jacketed...maybe cleaner because there is no copper fouling.
No one I know has complained about the change over or plans to go back.
