I have a Lyman mould #456192.. All I know is it's a 45 caliber.. Paper work from lyman is dated 1956.. Mould appears unused..no marks or rust.. thanks for the help to id this mould.

Bob,
My old Lyman books don't list a 456192, but they do list a 457192. They say it is a 350grain bullet originally designed for 45-75 Win and 45-70 Govt cartridges.
Looks to have 3 grease grooves and no real crimp groove, plain base.

Bob,

My Lyman manual dated 1953 only shows that #456192 is a 45 caliber 350 grain plain base, flat nose with three grease grooves. Was probably intended for 45-60, 45-70 or even more likely the 45-90 as it was the express round of its day and used 350 grain bullets. When used with a stiff load of black powder this diameter bullet would slug up to groove diameter, but would still fit in a slightly fouled chamber.

Hope this helps.

Elk hunter.. I think you are on the money. I have a winchester model 1876 chambered in 45-60. I didn't know the bullet wt/grain.. or if this mould was for this gun. My father in law passed away in 98 and i got this gun from his gun collection.. thanks for the info..

The older Lyman and Ideal moulds that I have had have cast large. Nominal may be .456, but I'd expect that mould to cast .458 or larger from WW.
