Executive summary: Inside 600 yards, the 168 gives up (almost) nothing compared to the 175 loads. The trajectories are close enough it matters little.aw25833 said:I have a question about the weights of bullets. I am just getting into long range shooting and trying to get set on a load to use. Obviously 175 grain slugs will carry a little better over longer ranges than 168 will, but how big a difference is it? It looks like the 168's are more common and a few dollars cheaper per box (speaking for the federal gmm), so for someone just shooting for recreation like me they might be a better choice. If the 175's are significantly better though, it would be worth it to get them. Any suggestions?
