[QUOTE="brianwinzor, post: 64152, member: 1067"] Reed, Interesting to hear that the Sierra 80 grain Matchkings are vapourizing at 3650fps in your 22/243. Most people who shoot 80 grain bullets in the 3600+ fps range say that the 80 grain Sierra Matchking is the only one they can rely on to hold together. Makes me wonder if you possibly may have a worn area in your barrel that is engraving the bullet sufficiently to make it fragment down range. I found that with the Sierra 69 grain Matchking in my 224 Clark, even at 3900 fps it gave good accuracy and no sign of vaporizing. I was excited yesterday to read on another forum that Sierra announced at the 2005 Shot show, that it is introducing in Mid April 2005 a 90 grain VLD style Matchking bullet. The ballistic coefficient of this bullet is stated to be .504, compared to .420 for the 80 grain Matchking. The introduction of the Sierra 90 grain bullet, together with the JLK 90 grain VLD, and the Wildcat 85+ grain bullets will now make life much easier for wildcatters (such as I) who want to experiment with 224 bullets in the 80 - 100 grain range. Regards, Brian. [/QUOTE]
