May make some diffrence as to the caliber & bullet weight. My recent testing Not exactly Apples to Apples was with a Bolt action 24" Grendel pushing 123 Gr SST's VS 129 GR Interlocks & in this case the SST.s experienced jacket separation. The core lock held together, mushroomed wonderfully & retained weight was great on Water jug test. Interestingly I was experiencing greater velocity from the 129's by 100 FPS or more.
