I regularly shoot 50 grain bullets from a 7 twist at 345,000 rpms and have never had one not arrive at it's final destination intact

These 62's were designed to be spun up fast since they have a bearing surface length comparable to something in the 85+ grain weight range, so I'm sure it's a nonissue.
Edit: I'd like to add that I listened to the engineer from Hornady on their podcast as he said these are at home in a fast twist barrel and not your average varmint twist 10 or 12 like guns in the past. He recommended the faster twist for these and also went on to say they are not for 223 gas guns (ar15's) unless you have a fast twist and would single load because they are too long to run at magazine length.
