I don't care for the hard wax lube either.
In fact, I recently found an old box of cast bullets and promptly relubed them with my own softer alox blend.
I load SNS cast bullets for my coworker. It's a 230 RN non coated bullet.
It has a hard wax lube but that's ok because I'm loading it to just barely make major.
Maybe about 740fps or less. At that speed you could use the fat off your leftover pork chops. 😂
(Ps. Yeah, I've done something like that before. I call those my "anti-jihad" bullets)
But getting back to the op, for back porch plinking you can't go wrong with a coated 230 round nose from SNS, blue, bayou, etc.
Properly loaded, they should feed and function any gun at fairly low cost.
My observation has been that bullet availability, in general, has been pretty good nowadays.
When the coated lead boolit craze began, I was attracted to it, but, I was getting such excellent results from my soft lube, I just continued.
But, the ease and ability to coat many at one time, rather than my, one at a time, method,.... was an itch I couldn't scratch!
Lately ( that past year, or,so ), I have been experimenting with MOLLY coating (in a vibrator) my cast lead, like I do with my 30-06sprg copper jacketed loads. I haven't had any negative results with lead /molly/ coatings, but, I never set up some extensive,serious loading / shooting, to get to a more definitive conclusion. Maybe, this conversation will reignite me!!
Especially, since lately I have been rebuilding my cast boolit stock,.... and, when I start loading them, maybe I will get more serious about moly coating,... thanks for the thought!
