How fast are you guys shooting lead bullets and how hard are they? I remember seeing Sir Ron's coated and gas-checked bullets back in the thread, but is anyone using bullets that are only coated and not gas checked? I'm interested in shooting some 18 Brinnell powder coated bullets as fast as I can without getting any leading.
Does anyone have a commercial source to buy correctly hardened, PC and GC bullets? Thank you.
I think the PC paint acts as a sort of gas check on the bottom of a plain-base bullet. And the PC paint also reduces leading whether plain base or gas check. I have several plain base that I use with PC paint and no grease lube. No leading problems at under 2000 fps with those, and I suspect BHN 18 would do OK for that too, though mine are harder. 2200 fps with gas check, PC paint, and BHN 25 works nicely. I need to see if 2500 fps with my 400-ish-grainer hardcast/GC/PC-painted bullets work well too. Still have not done that. So many possibilities.
A .459" cast bullet might shoot OK at less than 1400 fps in a .458 WM. For top performance at +1400 fps in .458 WM with groove diameter of .458" to .459" you must use bullet diameter of at least .460" to .461" it is true.
Have not bought any cast bullets for rifle except some Berry's .45-70 bullets that were .459" greasers, about 405-gr FN hardcast, about BHN 18-19. The SAAMI minimum groove for .45-70 is 0.456", and many .45-70 rifles are .457", or .458"-grooved. The Berry's bullet works best in my .457"-grooved .45-70 rifles at 1400 to 1800 fps.
