Hunted with 12ga for 40+ years. I bought a deerslayer 3 years ago.I wish I had gotten one when I started.6 deer so far and 3 dropped,the others didn't run more than 30 yards.I use Gold Partition but have heard the lightfields work well also.They do run about $10.00 a box though.I THINK THEY CLAIM 3 INCH DROP AT 200 YARDS.I sighted mine in about a inch high at 75 yards.They go where I shoot.
