If I'm being an idiot, please feel free to call me names as long as you give me the answer! :?

It's really pointless as the bullets I plan to load are 24 BHN but I would like to know how to figger this if I need to someday.

I have read Iowegan's posts on this numerous times and still have no idea. :|

And another thing, some of the loads I looked up were rated in PSI so now I'm really cornfused! :?

I don't know how much help this is to you.Bullet hardness is measured in "Brinell Hardness Number" (BHN) where a low number indicates a softer alloy. Someone came up with a formula for obturation that works well for all revolvers in all calibers when lead bullets are used. It is: BHN = Chamber pressure divided by 1440. If you know the bullet hardness and need to know chamber pressure ... Chamber pressure = BHN times 1400. The max powder charges for standard loads will run very close to 14,000 psi. In "Ruger Only" load charts, the high end powder charges produce about 25,000 psi.

I'm going to get me one of those Lee hardness testers For when I start casting my own bullets. I guess from reading the Lee catalog they have a conversion chart that tells you the CUP for your bullet.

I may be misunderstanding the question, but 1422*.90 = 1279.8......doesn't matter which method you use.....Deadeye said:

Deadeye, your calculation is wrong......it is not 1422.9....it is 1422 * .90......which equals 1279.8.....Deadeye said:Well I ran the math backwards both ways, at BHN-24 multiplied by 1279.8= 30,715Cups, 1422.9= 34,149Cups. :?

I never understood that Pie R Square thing either, my mom always told me Pie R Round, Cornbread R Square!

I got to thinking about this whole thing last night & it seems to me that unless your load data is for the exact gun, barrel length, primer etc. its kind of pointless anyway. :?

Thanks fer stratnin out my cypherin anywho! Things are gett'n so fer beyond my edgecasun now days! I thought I was good with just bee'n able to do my guzintas but now I gotta relearn it all becuz some eggheads want to be diffycult! I knew I shuda give'm Danebramage back when I wuz tak'n there lunch muny back in grammer scool!

i'm still on the 5x5=25 myself...............

don't guess i speak the computer lingo too well............

Its still the fault of the Eggheads! If * is for spreadsheets then they should leave it on the damn spreadsheets & give us X! That MBC webpage is not a spreadsheet!!!Terry_P said:That is the symbol is used in spreadsheets for multiplication. 5*5=25.

Maybe we could still find one & take his lunch money! It would make us feel better anywho! :twisted:

P.S. Thanks guys for all the info!

And since I'm really showing my nerd side, there are only two states of a computer.....it is either transmitting an electrical impulse of it's not....i.e., it's either on or it's off. So, everything you do at the keyboard does nothing more than transmits an eletrical impulse, or it doesn't.....see, computers are easy to understand..... :lol: :lol: :ugeek: :lol: :lol: :lol:
