Use the 55 gr SP w/ cannelure all the time just got done loading 1000 of them. Worked up a load in 223 Mil brass for my M700 VS cross checked them in my DPMS Oracle , MP-15 build/PSA upper and my R-15 also work in my HOWA truck gun and M77 ss boatpaddle. FL sized them, trimmed all to min, VLD chamfered inside, regular chamfer outside. charged the cases seated the bullets .Then I ran everyone of them thru a Dillion case gauge to eliminate any problem ones from use in my AR's. Least expensive 224 bullet out there and they shoot well. Around here they can be had for $90/1000 bulk buy them by the 100 count and you end up bleeding down the backside of both legs. My everyday working bullet in the 223 and 22-250. MB
