Just got myself a Master Caster last week and am trying to develop an alloy to shoot out of my Glock 35 and make major PF
I'm using a Magma 185 gr FP FB that weighs out to over 190gr
My current attempts at the following alloys came out as follows:
1 WW to 1 Pure Lead Water Quenched = 22 BHN
1 WW to 2 Pure Lead Water Quenched = 17 BHN
1 WW to 3 Pure Lead Water Quenched = Waiting 48 hrs for results :popcorn:
( 1% tin added to all of the above; all BHN measurements where made after 48 hrs after casting )
The reason for using pure lead and quenching is that my pure lead supply is triple if not more than all of my other alloys.
The powder I'm going to use will be Red Dot. I have over 16lbs that my dad got from an estate sale. I have used it with 180gr plated and jacketed bullets and have had great results.
Quick Load puts 3.9 gr of Red Dot with a 190, LEADEx FN 18TC04062C CFPRS COAL 1.135" out of a 4.6" barrel @ 920 FPS Giving a PF of 174.8 well over the amount I need.
I plan on loading thousands of these so I can practice and compete all with the same load.
So my question is will the BHN soften enough after a long period of time to cause leading or effect accuracy?
I'm guessing that using a smaller amount of wheel weights will decrease the effect of age softening; and with my final BHN alloy will probably be around 12 and a decrease of 1 to 2 BHN shouldn't be a problem for the lower velocities I'm using????
