I have not had a chance to try out the hornady 178's yet. I saw the advertised B.C. today and will give them a try. Just curious if anyone has any thoughts on them. Most everyone I shoot with run smk's and berger. I had some great results with the 208amax on my 300wm. I just ordered a box to try out. I will be running these in a 700sps 20in barrel.
