Hey guys & gals, another wild idea: Just picked up a box of Speer Gold Dot 40 Cal 180 gr, and fired a few rounds from my G22. Lined 'em up with a couple other HPs I have, and made a discovery. The diameters of the hollow points are all different! Now, Mas rates Gold Dots second only to Ranger T's. Golden Sabres are supposed to be fairly good, with WWB JHP a weak 3rd. (At least that's my impression of the last 2) Most effective = largest diameter Least effective= smallest diameter So my question is can the diameter of any hollow point be taken as a predictor of the potential effectiveness (i.e. "stopping power") of the round? An interesting sidelight: Usually when I shoot at a block of firewood lengthwise, it stays put. This afternoon, the Gold Dot's consistently blew the wood right off the stone it was resting on! Granted, the wood was dry punky cedar. I think. Later, I'll split that block and check on penetration.
