With my 6.5's I've found myself using Speer Hot Core's again after years of Hornady spire points. Used Speer 160gr Hot Cores in a 7mm mag years ago, great bullet! Now I have hot cores in my 6.5's and they are shooting better than I need. First I've heard about "Speer Impact" bullet's. I believe we really don't need new type bullet's as even the bullet's I don't choose to use work much better than needed. I suspect Speer might be simply looking for something new which, if they work well, will bring them a bunch of new business! Most all bullet's have a similar trait. Place them right and they simply kill things dead right now! I suspect the only projectile not in a modern hunting rifle is a 20mm RPG round! of course different bullet's do have different qualities and different thing's appeal to different people. Two thing I'd like to see if Speer is simply looking for a new sales product would be a 130gr 6.5 bullet and if they made the hot core bullet's with a mag tip I'd be a happy camper. Some people will find a couple thing's hard to believe. Rem core locks still kill things as dead as they ever did and you can only kill an animal so dead!
