Economical is sort of a relative word............

The Hornady 55 gr V-Max or the Nosler 55 gr BT are both pretty good bullets in both my bolt guns & AR's but seem to be best in a 1-9" twist gun..........1-8" works OK too & they will certainly shoot in 1-7"'s but 55 gr is not a 1st choice in a 7 twist for me.
