I reloaded my 270 with the 130 grain SST Interbonds and tried them out yesterday.My groups at 100 yds were excellent .I also shot one into a line of several 1/2 gallon plastic bottles filled with water and recovered it.My reloading friend and I were very extremely pleased with the amount of mushrooming it did (more than any bullet I have seen).It weighed 115 1/2 grains afterwards.I am very impressed that it is as advertised by Hornady.Of course ,I can' t wait to try it out on a whitetail this winter and see if it performs as well on a nice buck as it did on those plastic bottles.
