Lead Alloy Ratio for a Moder 92 Winchester

[terryt]

Hi:

What would be a good ratio of lead & tin for a Model 92 Winchester in
32-20 Made in 1901.

Thanks,

2% tin is pretty typical to add to a mixture of Pb and COWW. Your mixture of Pb and WW is a little more dependent on which boolit your planning to shoot.

Read the site that was suggested above. The 32-20 was never meant to be a barn burner. It was used for small game hunting in the woods of the EAST. It's a fun caliber to shoot with lead bullets that are in the 20-1 area up to say Lyman 2. This range will cover your uses as pointed out by Glen Fryxell, the barrel fit needs to be checked by slugging. Later David

For hunting ammunition in the black powder lever gun calibers such as the .25-20, .32-20, .38-40 and .44-40, with either smokeless or black powder loads approximating the velocity of the original ammunition, only the minimal addition of tin to pure lead to get good castings is needed. 1:75 tin/lead is fully adequate. Harder than 1:30 is unnecessary. Indeed, pure lead may be used with good results in a smooth barrel up to full black powder velocity and will give better hunting performance than harder metals.

A 50-50 mixture of COWW to soft plumber's lead works very well, as does 1 part of linotype to FOUR parts of pure lead.

These same alloys give optimum field results in traditional, non-magnum revolver calibers such as the .32 S&W Long, .38 Special, .44 Special and .45 Colt with either standard-pressure or +P loads producing subsonic velocity, such as in the .32 H&R Magnum or "medium velocity" loads in the .44 Magnum using 7.2 grains of Bullseye or 9 grains of Unique with 200-240 grain bullets, approximating .44-40 loads for the Winchester '92 or .44 Keith Special levels.

One more thing, throats can be a bit tight relative to diameter across the grooves in your bore. I have to strike a very careful balance or I end up with not enough room in the chamber throat to allow for case expansion for release of boolit.

Thanks for the info.
