What lead mix and cooling method is best for expanding boolits?

[tayous1]

So looking to make some HP boolits for my 45 LC and 45 ACP and instead of trial and error I thought I'd come here and see if anyone can help me out!

Only advice I was given so far was to air cool but they never answered if they are cooled slower would they expand better? I was also told to just use the range scrap I have and throw in a pound of pure lead.

Thanks for the advice now just need help with load data for the 275 gr 452. Boolits for my 45lc.

20:1 is my choice for most all my HP hand gun casting. That I want to see expansion. I also Powder Coat.

I would just use the range scrap you have , should be soft enough , air cooled is fine , water dropped or quenched is to add hardness , as to load data , it boils down to what powder then do your load workup . I have gotten away from big and heavy in my 45 colt as I am shooting the Uberti 73 revolver and rifles and the Blackhawk is doing rest and relaxation . Steves reloading data pages has 275 grain 45 colt http://stevespages.com/451p_3_275.html

Your range scrap might work fine just as it is, maybe not. you won't know until you try. You can always add some pure lead, if needed. Here's a good link on hollow-pointing:
