I have both 10's in CP and PRI, my PRI's load longer @ 2.305 and the CP's like 2.295. I usually load out to 2.290 max so I can use either mags. I have no issues with either mags and both feed well and have never needed any reworking at all.
On a side note what I have noticed about CP 15-17 depending on the followers are if you experience and feed problems I set these mags aside, clean them and continue to break them in. All became reliable after the 4-5 loadings, and this is with out tweaking the feed lips. YMMV
