I have a buddy that has used 55 grn Hornady and Sierra's for 18+ years in his 22-250. I have used Win 55grn factory loads to kill deer, and the farmers teenage daughter also has used the win 55grn for 14+ deer including a north MO 10pt 200+lb dressed buck.
That said I have my dedicated .223 deer loads with Sierra 65grn right now, and have a 75grn Amax load that shoots well also.
