My dad complained about Hornady's too . Back in about 1972 he and 1 of his loading buddies weighed full boxes of bullets from Serria Hornady Speer and Nosler in 257 and 308 and concluded that they were all within .5 gn of each bullet in that box and within 1gn of what they should have been . After all that we shoot 308 Hornady's 257 Noslers 224 Serria's 357 Speer's . All shoot an inch or so and the Hornady's shoot about 100 fps faster than the book says .
