Lyman bullet sizer guide

[wheelgun]

Anyone know the correct top punch number for .40 cal round nose 180 grain pistol bullet for Lyman 450?

Can not find lyman catalog on line and I have to order out of province.

You will find the number with the bullet moulds and they don't list a round nose.

If you can't find the right number, you can use any larger RN top punch, as the nose will centre itself, any other top punch will probably damage the bullet. Some folks maintain that this type of arrangement, where bullet centers itself in top punch is actually more accurate, I tend to agree IMHO. Sometimes you have to experiment.

I am using Magma Engineering moulds with the crank type caster. No lyman information is listed with these moulds. Thanks.

I will try the larger round nose as suggested. I have an assortment. Thanks.

Here's pictures of about all of Lyman's bullet designs:

Here's a cross reference from molds to Lyman top punches (go to "Moulds" at the upper left, then scroll down to "Lyman Top Punches"):

If you want your bullet forced all the way down into the Lube/sizer die, you will need a top punch smaller than .40
