Well, I started to cast my own last January after hunting season '08. I was dissapointed with my 300gr SST's, yes they dropped the deer in its tracks but al I ever recovered was a copper cup. So I bought me a Lee C452-300-RF bullet mold. I tried some loads with different wieghts and sabots and finally after much frustration I found a load that my TC Encore likes;
-Harvester E-Z Load Premium High Pressure sabot, 45 cal 300gr or more.
-110grs Triple 7 FFG powder
-PR Bullet Vari-Flame Primer adapter (Federal Match small rifle primers)
and the Lee cast bullet.
At 100yds my groups are just under 1"
, I recovered some and they mushroomed nicley so my lead mix is good, lets' see a "smackdown" on a deer this fall
I am also using an MTM Predator rest and a Nikon Omega 3-9x40 scope
