Free: Contests & Raffles.
I've never shot the ELR put the original powerbelts had terrible terminal performance on wet newspaper and plywood. If you want to know what the ELR's will do I suggest making up a bullet trap with wet newspapers or old test books and maybe throw in some plywood to simulate bone, or anything else you might have around. This will actually be better to gain knowledge about performance than anecdotal data from hunting scenarios because hunting scenarios very by many more factors than you can account for. Compare 3 or 4 bullets at different speeds (you can change distance or just powder loads) and you can at least have a good comparison of bullets your interested in even if your bullet trap is ideally suited to match an animal.
