To add some more data/experience to this issue.
I've used Hornady 75 gr HPBT bullet for 6-7 years now and over 40,000 of them in that time.
For the past couple years they were all shot through a 24" or 26" 1:8 barrels with a load of 23 gr of 8208 in an ar15 based 'spacegun'. The barrels were all either from WOA or Green Mountain [finished by a smith]. Never chrono'd the load, but it would probably be in the mid to high 2700. Never a blow up.
This winter I've started using a bolt action with 26" barrel and 1:7 twist. The barrels I've used so far are Shilen with 6 groove rifling. Chrono'd the load today - 2820. Through a little over 1000 bullets from a lot made in 2018, one disappears about every 20-30 rounds, sometimes several close together. Through a couple hundred bullets from a lot made in 2019, none have blown up [yet] - including ones with 23.4 gr of 8208 - which should be 2860 or so.
Over on the National Match forum, someone sectioned a H75 and a S77 - the jacket on the S77 was, as I remember, 20% thicker. I think the thinner jacket along with the jacket thickness varying from lot to lot causes the problems with Hornady's bullets - at least with the H75's.
I have two barrels with 5R rifling and am anxious to try them out as soon as my new action shows up.
