NOE 314 198 SP From wheel weights

I have been casting the NOE 314 198 SP using wheel weights and salvaged range scrap mixed together, using a 5 cavity mold. My bullets weight around 210.3 gr instead of the 201 gr as specified. Which alloy would allow me to get closer to the specified weight of 201 gr or 198 gr instead of the 210 gr?

If you look at the bullet drawings, it shows the weight with the alloy.  Usually the NOE drawings feature the weights using a WW alloy.  Any softer and the bullets are going to be heavier.

Ok, so a harder alloy would be necessary? I musy also add that here in South Arfica our wheel weights might have more lead than the ones used elsewhere like the US. So what is the alloy composition to cast 201gr NOE 314 198 SP bullets  instead of 210gr bullets?

U.S. current (older alloy was harder) clipon wheel weights average 3% Antimony, .5% Tin and .25% Arsenic, balance lead.  Source:  bumpo628’s alloy calculator available at http://castboolits.gunloads.com/showthread.php?105952-Lead-alloy-calculators.

Thanks for posting that, I was going to look for that same calculator to help him out but you got there first, high five!

Not a problem, we should note, though,  that with cast bullets seating depth is more important than exact weight as far as pressure goes.  That is to say, don’t get hung up on what your alloy makes a bullet weigh, what matters is how much of the case it is filling.
