[QUOTE="benchracer, post: 842774, member: 22069"] I own a copy of Hornady's latest manual, but I am not in a place where I can get to it any time soon. If memory serves, Hornady breaks the .308 down into separate sections for bolt action rifles and for service rifles. Are you sure you're not using service rifle data? Hornady lists a mv of 2600 fps for their standard match ammo with the 178g BTHP. You should be able to better that slightly with a 26" barrel without much trouble. As for your flattened primers, that is not a reliable pressure indicator. Cratered primers would be a defininte red light. Flattened primers can happen at low OR high pressure. One thing to pay attention to is if your loads are smoking the case necks. If you are getting smoked/sooted case necks and flat primers, that is a pretty good indication of a LOW pressure load. Many factory loads will flatten primers, FYI. As for the bullets themselves, my friend was having issues with the jackets coming apart in flight. He had several of them splatter against plywood backers @ 600 yards. Accuracy was very erratic. I strongly suspect a bad batch of bullets. If they are shooting well for you, by all means stay with them. I have been shooting 185g Berger Classic Hybrid Hunters and RL-17 with very good results. The bc of these bullets is very similar to the Hornady BTHP's and the Hornady bullets are quite a bit less expensive. [/QUOTE]
