Well, I cast some bullets, lubed and sized them, took them out and shot them. Ran 12 moons thru it and it looks like I'll be ok. Some traces of lead but nothing extreme.
I haven't cast bullets for 40 years, I forget what a mess the lubing part is especially with bevel base bullets . I'm liking the powder coat idea more and more.
I mounted a red dot to test for accuracy and was pleasantly surprised with the results. Two inches at 20 yards...... works for me. Looking down the bore, the rifling looks almost non existent, I'm surprised it shot so well.
