When I first started handgun hunting about 4 years ago, I was only interested in jacketed bullets. Well, today I was able to sneak off to the range for about an hour with a hunting buddy who is also on this forum. I brought with me a box of handloaded 180 grain Cast performance bullets loaded over 12.9 grains of W-296. This is a new load for me, especially after last year's results with the 165 grain corelokt ammo. I also had some 170 grain Speer GDSP loaded over 15.4 grains of Li'l Gun. I must say, I am impressed with the CAST bullet. I do not have a chrony, so I cannot speak of the velocity, but I really like this round. Shooting my 6" 686, I found the load to be loud, but the pressure and recoil was noticibly less than the jacketed loads. I only shot a couple dozen rounds of the cast, but my best was a group of 4 in about 3" at 50 yards, with open sights. These bullets have the gas check on them, and my barrel did not show any signs of leading, whatsoever. I think I'll call CPBC and buy some more bullets...I am sold!
