gc mold to flat base mold

[wayne h]

I converted a lee gc 30 cal 165 gr mold to a flat base mold. I am doing this in an effort to shoot without gas checks. I have 700x/ unique and 2400 powder coming out my ears. What would be a good load to use for plinking that will not cause leading? This mold drops at .309. Thanks. Wayne H.

caliber ?

if its an -06 then go 8g-9g Unique,10g-12g of 2400 or 6.5g-8g of 700X.I have used all three powders.I use LG Pistol primers also.These loads chronograph from 1000 fps to a bit over 1200 and dont typically lead the barrel.You may get a very light lead/carbon fouling in the throat after a few 100 but two GC loads clean it out.
