MedicAJ Posted December 29, 2017 Share Posted December 29, 2017 So... Hypothetical...1 1/8oz 7.5 going 1300fps or 1oz 7.5 going 1350fps. Physics tells us that velocity has more effect on energy than mass, but what's everybody's practical experience? For either clays or KO steel.

RJH Posted December 29, 2017 Share Posted December 29, 2017 (edited) I feel for steel heavier/slower loads work better because more total weight to start with and lower velocity generally leads to denser patterns. faster loads generally seem to spread quicker so there could be an advantage there on clays. This assumes all else equal, and is what I have experienced Edited December 29, 2017 by RJH Link to comment Share on other sites More sharing options...
HCH Posted December 30, 2017 Share Posted December 30, 2017 I like heavier loads. Link to comment Share on other sites More sharing options...
Paul49 Posted December 30, 2017 Share Posted December 30, 2017 Kinetic energy is equal to 0.5 times mass times velocity squared, but kinetic enegy doesn't have a real directionality to it. Momentum is the product of mass times velocity and it assumes the mass is moving in a straight line. So momentum may be more relevant to knocking things over. Many pistol shooters who are trying to flip an MGM spinner go to heavier loads, probably for the higher momentum. Looking at white box Winchester 9 mm: 115 gr at 1190 has a muzzle energy of 362 but a momentum of 136,850 (gr x ft/sec) 124 gr at 1140 has a muzzle energy of 358 but a momentum of 141,360 147 gr at 990 has a muzzle energy of 320 but a momentum of 145,530 And I once saw a guy shooting .45 ACP wearing a Tee shirt that read "sometimes fat, slow and heavy gets the job done".......
