Has anyone used speer hotcore bullets in their tenders for deer? I've read somewhere that they will expand at lower velosities then other softpoint bullets. I just got my 12" 257 Raptor from Gary Reeder and would like to try the 100gr speer and the 87gr hornady sp varmint bullets for deer hunting this season.the 100gr bullets should be getting 2300-2400fpc mv. Still working up a good load and I don't want to have to order nosler bt's. Thanks for any info.
