[QUOTE="liltank, post: 561136, member: 13275"] The break down: 20 cal Berger 55= .381 .224 cal 55 V-max= .255 53 V-max= .290 Sierra 55 Blitz King= .271 To get equivalant BC of the Berger 55 you need the following: 77grn SMK .371 68grn Hornady BTHP .355 77grn Berger BT Match .376 Your getting the picture here I'm sure. You have to go to a substantially heavier bullet for caliber in the .223 to achieve the same level of the performance of the 20BR with a 55grn bullet. Not to mention the 20 cal is going to be moving at a much higher velocity. Tank [/QUOTE]
