I wouldn't use the maximum load at first of course. Does anyone have a Speer reloading manual that has data for 150 gr hot cor bullets? (.308) I only have a Lyman manual right now. Help would be greatly appreciated.
You will never be able to match all the components exactly. Manuals are not recipes, only a set of guidelines. That is why they list a "Start" and "Max".
Do not go below "Start" and do not go above "max". If the data lists one charge only, that is considered "max" and the "start" charge should be 10% less. When someone says to drop the charge down by 10% , they do Not mean 10% of Min/start, they mean 10% of Max.
It is perfectly acceptable to use load data with Same Weight and Similar Construction from different manufacturers and designs. So, with your Speer copper jacketed cup-n-core bullet you can use data from other copper jacketed cup-n-core bullets.
It is best to gather as much data as possible from as many sources as you can find.
For the 308 Win with 150gr bullets with BLC-2 I found this.
Lyman 48, Start-44gr...Max-49gr
Speer #13, Start-40gr...Max-44gr
Sierra #5, Start-43.6gr...Max-48.4gr
When I find an odd duck in the mix like the Speer data above, I usually drop that one. I keep it in mind and I don't forget it, but I kinda ignore it when working up a load.
That said, With the above data, I would start at 43.5gr and work up towards a max of 49gr in .5gr increments. Three of each.
