One of my favorite internet auction sites is the EBAY cast bullet section, they have several hundred bullet casting related items for sale or auction.
I found a single cavity .452 Lyman mold with handles for not too much, and wanting something to replace the RB in my 45 Ranger I jumped on it.
This morning I cast some up with pure lead that I also got on EBAY. They came out a little large at 454 but chambered fine in the Ranger 45 without sizing. With pure lead they came out at 195 grains.
I did a fill of 3800 PSI and shot two shots, refilling each time to check my zero established with 420's. I was about 6 inches high at 30 yards with a velocity of 875 on medium power, the two shots went into the same hole.
I readjusted the POI with the little Burris 2x7, filled to 4000 PSI and fired one over the chrony, I was greeted with a meek "Ping", and the velocity was 712 FPS, I fired another and got 875 again, and then fired three more shots of 1033, 1073. 1022.
I checked the pressure and was at 2600 PSI, so I refilled to 3600 PSI and was back at 1066 FPS.
Informal accuracy while doing the chrony testing indicated that at least at 30 yards, this should be a one holer at 500 FPE. With a 70 yard zero, it is never more than 1.5 inches from the POI out to 80 yards where it still has 390 FPE.
I think I have found my plinking load and small/medium game for the Ranger, all in all I only have $50.00 in the mold.
