The only negative has been related to the rearward position of the lube groove. I designed it that way to be able to load it in 40 S&W brass as shown in the pic; it works well but does give some leading towards the muzzle at higher velocity. No leading issues below about 1150-ish fps. Accuracy is as good or better than any other cast bullet I've tried. I've thought about ordering a similar design, but with a deep crimp groove in the middle of the front driving band, similar to that Mihec bullet on the left of my pic. The crimp groove would be used as a lube groove, without taking up as much space as a standard lube groove.
You should measure the length of those 220gr SWC's; they are probably too long to be of any use in the 10mm. The SWC design is not efficient when powder capacity is limited. My 215 WFN bullet measures about .675" long. The Mihec 220 on the left measures about .710" long. Any longer than that, and velocity potential drops off in a hurry, and the base of the bullet gets seated into the tapered part of the brass, causing bulges and chambering issues.
