Cast bullet question

[Wildbillz]

Hi All
I was looking at 9mm cast bullets the other day. I saw 115grn cast lead round nose bullets. None of my manuals list a load for this. That got me to thinking and there seams to be a few that are like that. So where do you find load info on these odd weight cast bullets?

115grn 9mm
170grn 40/10mm
185grn 45acp

There seams to be a whole market of them. How do you determain where to start on somting like this?

Thanks
WB

Try the Lyman cast bullet handbook or their reloading manual.

If ya use data for a slightly heavier boolit you`ll be ok within reason though !!

I`m lookin at my castbullet manual now , what powder ya gona try ? too many to type !!

Start working up from the light end of a jacketed bullet or a lead bullet which is heavier.
Lead bullets will not have as much pressure as a jacketed bullet in most cases taking into account length of bearing surface.

From my dirt bin memory of working with cast bullets in several 9MM semi-autos and revolvers. The 124/125 grain cast lead round nose bullets were easier to load and make function more uniformly. I never delved very deeply into the why of that occurance I just liked how much better it was and used it to my advantage. The 124/125 seemed to take the steel plates down a little better and were more consistently accurate from all my hand guns. I don't do much with 9MM now so use the opinion if you like.

I can use Bullseye, Unique or Win 231. Mainly looking at the 9mm 115grn and 45Acp 185 swc.

This is the listing for the 358345 which is a snubby lookin 115gr swc, the aol mite not help but lists it at .997 , I know that seatin depth is touchy subject on the 9mm

The manual says to use WW cases & primers for the 9mm

BE starts at 3.8gr. for 1035fps & 22,800cup -- 4.9gr. for 1200fps & 31,000cup

231/hp38 is not listed !

For 45acp

BE starts3.5gr. for 660fps & 6,00cup ---5.0gr.for 890fps &12,300cup

231 for acp
