Of the speer line the only bullets I have used have been the hotcor in 25cal 120 gr 270 130 gr and in 30 the 150 and 165 gr. I have only recovered one a 150 gr hotcore from my 3006. It weighed 75 gr or 50%, whitetail buck at 125 yards. The rest have. gone clear thru and I found them to be one inch or less at 100 yards..I like them and think they are a very good bullet, but their marketing does suck. They are extremely difficult to find in Canada, and if Speer are trying to kill their handloading supply business they are doing a good job.
