I started out with cup and cores in the late ‘60’s......308 Win. and .375 H&H! Went to Nosler Partitions in the late ‘80’s....in a 270 Win. Then to Barnes X Bullets in the early ‘90’s. The only bullet that I considered a “bullet failure” which exhibited utter and complete “disintegration” was a 300 grain Sierra from an H&H, at well under 2800 fps impact velocity. And, 2 of the three were small big game....the other an elk! Those 300’s when fired into a test median right beside a 270 grain Hornady.....again failed miserably, while the Hornady performance was very impressive! I could not find any remnants of the Sierra.....perhaps if I had used a “screened box”, I may have found some bullet material. They were however, pretty impressive when used on prairie dogs! memtb
