[QUOTE="koonazz, post: 2186128, member: 29836"] I'm doing load development for a 257 Wby with the 98 gr Shockhammers right now. What I've learned so far, they don't seem to build nearly as much pressure as conventional bullets. They're very fast. I've seen almost zero copper fouling after shooting them. And so far two different powders have gone WAY over book max before hitting pressure. (like 8-9 grains over book). They don't seem to be finicky about seating depth and they seem to be very accurate. Some of my 10 round .3 grain jump pressure tests a have yielded 1.5" groups. [/QUOTE]
