[QUOTE="Lou270, post: 2525916, member: 5352"] I think hammers probably require more twist to go straight because they blow the front off and end up a tube. The density of an animal is many times greater than air so i doubt any sg value we think of for external ballistics is applicable to same degree but seems like ups odds of not tumbling once front blows off A more traditional lead bullet expands and had a mushroom or some deformation up front along with a shorter shank. Even something like a barnes with a longer shank most of time has a mushroom. In either case the center of gravity is more forward so less likely to tumble than a skinny ‘tube’. Partitions often end up backwards but have no issues expanding as they are pretty soft nosed. Any case, I am intrigued by hammers and have a bunch to try but I dont think all bullets are equal and to get the beneifts of hammers may need faster twist than other bullets by their unique design Lou [/QUOTE]
