Got me another "new" mold- it's an old version of the 225415, an Ideal, single cavity, without vent lines. [smilie=w:
Somebody here once commented on the differences over the years in the manufacture of various molds, and the changes in cherries, etc.- this is a good example. I don't know how old the Ideal is (before Lyman bought them?), but the Lyman was made under 20 years ago (educated guess).
Cast from my mix of Lyman #2, which is about 12 BHN, and throws very close to the factory specs-
The new version weighs 56 gr. with the gas check and lube.
The old version weighs 51 gr. with gas check and lube.
Diameters were very close in comparison, too- both cast at 225 to 227 in overall roundness. :smile:
There is an obvious difference in the length and nose shape- the older is shorter by the length of the gas check, and more truncated.
I think I like the looks of the older version better, and it should do well in my 22 Hornet- this will fit the clip much better also. No need to seat as deeply, and is more near to the 225438 mold I have in final weight. The 225438 did very good this past summer in accuracy tests. :smile:
Don't know how good it shoots yet- that won't happen until spring now. Next break in weather temperatures will have me in the shop casting lots of the older version! [smilie=p:
