I think that Barnes just runs any blems with some polishing compound and then they are not blems anymore. I have had good results using Nosler BT or sometimes Sierras to work up loads and then switched to Barnes which in most cases shoot to the same sight setting.

I think there is a slightly higher chance of a Nosler PT failing than a Barnes but the percentages of either failing is about like getting struck by lightening. Others would reverse the two, especially the pencil through boys.
