View Full Version : 32 Winchester Cast loads

12-11-2007, 01:24 AM
Ok my first post on this site, looks like alot of info here. I have a question about some load info for a 170 gr. GC cast bullet in my pre 64. I cant seem to find any info. I have 3 manuals Hornaday, Lyman 48th and the Speer #13. Great info for Jacketed and soft point but not cast. Any help here would be great.

Welcome to the forum hicap.
You can use .30-30 data with cast for your .32. The Lee manual is a good source, but it lists only Hornady powders. The Lyman CBH is an even better source.
It is easy to calculate reduced loads for cast. Look up the jacketed loads, then subtract the minimum load from the maximum. Take the difference and subtract it from the minimum load.
Max load - Min load = Difference; Min load - Difference = Cast Starting Load
Work up from the Cast starting load in 1gr increments. If your groups suddenly start opening up, check your barrel for leading.

Welcome hicap!

If we are talking about the 32 Win Special, E. Matunas gives the following loads in Metallic Cartridge Reloading for a 20in bbl:

165L/20 to 31gr 3031/1300 to 2075fps

Ken Waters, in Pet Loads, gives for the 180gr Lyman 321297, with IMR powders and a 24in bbl:
16gr 4227/1400fps
18 to 22gr 4198/1500 to1750fps
25gr 3031/1650fps
28gr 4895/1700fps
