[QUOTE="comfisherman, post: 2678835, member: 8394"] Last 15 years has taught us modern components allow for us to get away with more pressure than our pressure wives tales would indicate. Nosler doesn't have a load that breaks 4k I think hogdon does with ramshot hunter and blc-2. Hammer bullets are no more mythical in performance than any other 55 grain bullet, and no more than moly, boron, Teflon, etc that came before. Weight and pressure, can get more velocity one way or another but no free lunch. The miracle is in the unknown, it's the same reason so many wildcats are so successful up until someone slaps a pressure sensor on it. 243 runs at 60k, similar more recent cartridges like 6.5 creed do 62. My guess is you can hit much higher speeds, with more pressure. We know in higher pressure rounds varget scales pretty good to the mid 60s, so 4200 at 62, or 63 is probably doable. And factoring in modern brass and primers go Un noticed with our finely tuned 100 year old pressure sign wives tales. [/QUOTE]
