I ended up with the Interbond purely by accident. I use the Hornady's for my big bore practice ammo as it's much more "economical" than Swift A-Frames. But to my disapointment my beloved Swift's would not make my desired velocity due to Deeper seating of the Swift's and the 21" barrel on my new Lott. To my surprise my "practice" ammo reached my desired velocity of 2225fps without the dreaded powder compaction so common in Lott's... Well to get to the end of this long explanation, I fired the new Interbonds into a dirt bank and retrieved two bullets. I know this is not the most sceintific of tests, but the jackets peeled back like Barnes-X and the bonded lead stayed with the jackets all the way... My next buffalo with the Interbonds will be the true test.. BTW, factory Hornady Lott ammo velocity was 2210fps in my shorty gun..450D
