^, ^^, ^^^ Same boat. I do seated calf raises with the weight sitting directly on my legs in the power rack, and can grind out a set of 8 with 515. Calves are 15.5". FML. Also full squat 315x5 with 25" legs. Haven't PL squatted in a while, but probably close to 475 if my squat/DL ratio is still the same (just hit 5 plates).
My legs stay very lean compared to the rest of my body, though, so that may have something to do with it. Abdominal skinfold right now is 27mm, and legs are 8mm.
Just gonna have to put in the extra work, that's all. As soon as I reach my current goal, I'm going to start focusing harder on legs. Only working them once a week ATM, but I'll probably go back to two or three times a week (hopefully soon).
