IF you don't mind picking pellets from the bank. You're kinda stuck using someone else's idea's for bullets. At my range there's a whole lot of shooters so picking pellets dont' take forever. I can pickup 4" in a bucket in half an hour and barely carry the thing to the trk.
Lee's 6 cavity molds only cost $37, plus $13 more for the handles. In all, $50, then IF "as cast" don't do it, I'll slug the barrel and order a sizer die 1-2 thousandths over bore size for another $8-10 and be in business.
I've found most all recycled bullets are of a good hardness and won't lead a barrel even with extended use. BUT: you cannot exceed about 2300fps or they will lead the bore. I cast and shoot cast bullets by the buckets full and don't get too excited about cleaning my guns overly often. When I'm done shooting is the time to clean them. Unless I'm going out again within a couple days, then it's likely I won't even clean them then UNLESS it's the black powder stuff, then I WILL clean right away and clean a second time within a couple days, plus oil it up lightly too.
Best bore cleaner I've ever found is that fairly new stuff: Blue Wonder Gun Cleaner. I just fill a bronze brush with the goop, run ten strokes, take ten minute break, ten more strokes and patch a few times til it's cleaned out. Then oil it up good so it don't flash rust. That stuff will take everything out of a barrel. Lead, copper, plastic, bird droppings an even spider webs IF you've got em. Don't know as I've tried to use it on mud dauber's work yet or not. But, I'd bet it would work there too.
Long as you cast bullets are hard enough you can't mark it with a thumb nail, and is a little bit over the bore size, not loaded to max jacketed velocities you shouldn't have any problems with them shooting well, or leading a bore either one.
I've got a whole lot of scrap bullets from an indoor pistol range. That's the ideal source for me. Free for the shoveling up and all I desire to haul off. This range produce's two 5 gallon buckets a week.
When melting down, I put a screen over my kettle, scrap on that and melt it with a second weed burner. That way all the high value copper jackets aren't ruined with lead melt mixed in it. The scrap yards around here won't buy that kind of mess, but, they will pay a good price for clean jackets. $40-50 a bucket full isn't wasted time IMO.
Oh yeah, I shoot those 115gr RN 30cals in my '06 with 4-10 gr Red Dot. That's a great loading for teaching women and kids how to shoot the big guns without hurting or scaring them with the recoil and blasts.
Good shootin,
George
