Hi all,
Yesterday was the first opportunity I had to shoot my cast boolits (308win) at the range......and I was pleasantly surprised.
The boolits are Lee 150gn 309's GC'd 155gn weighed). They were H20 quenched antimonied Pb and came out pretty hard. I dont have a hardness tester so i estimated they could handle 18000psi. I used Quickload to come up with suitable loads.
Powder was AR 2208 (Varget). I had 4 loads however the 2nd and 3rd showed the best groups of 3/4" elevation at 100m!!!! These were the middle loads of 32.8 and 33gns. The others had 2" dispersion. They shot 10" lower than my standard hunting load behind a 150gn sierra. No windage adjustments were needed.
I shot these groups quite fast as I was in a hurry and there was a small amount of leading present....I think this is due to too little lube. This is something I can live with as it is a hunting rifle and I will only take 5-10 shots before cleaning anyway.
I'm real happy with this and i cant wait to use them chasing deer in a few weeks!
Cheers,
BD
