read just a little about these.  i have some and plan on shooting them in a 14 twist 6 BR, esp for varmints.  they have a large space ahead of the lead core.  i hollowpoint match bullets and these should be quite explosive.  anything specific about them as to jam or jump?  do they have a powder preference?  are they a "here today, gone tomorrow" bullet?  thanks.
