I have casts many calibers- using Lee molds. Any issue I had, I was able to correct. What is new to me. Lyman mold for 223 which is cast iron, I believe, compared to Lee's which are Allum.
This is my scenario--
1- new mold, different material.
2- First time I have used a spray to assist with bullet drop- Graphite type
3- Brin. scale of 35 using Lee tester, dimple measured .4 to .45
Theses are my problems;
1- Tiny thin burrs at the top and side seams of bullet, I can scrap off with finger nail, but they should not be there.
2- all bullets are speckled, none are shinny like I'm used to having.
3- So-SO to poor lube grooves at the bullet base.
4- Lead sticks to spur plate. never seen that before. I had to actually poke the lead hole from the back side...even after spraying the cutter
What is right--
1- Bullet base has perfect cut off.
2- Top 2 lube grooves are very cleanly cast.
New Mold was properly prepped prior to use. I tried lead temperatures of 800, 700 and 600 same results.
Questions. Is it possible that the graphite on the mold doesn't allow it to seat 100% Is my extremely hard lead causing an issue? AmI missing something I haven't thought of, like maybe I'm just too old and senile to do this any more
PLEASE give me your thoughts
