Obviously you want to work up your own loads in your own gun carefully. But here is what I have found so far with my HH .223. I tested both the VLDs and the SMKs on paper at 300 yards and the VLDs actually showed a better grouping than the SMKs. 2.5" instead of the SMKs at 2.8". One variable was that I used a new batch of VLDs that had a much more uniform meplat than the batch I tested at 100yards that gave me a .8" group. I have a feeling that the new batch of VLDs will be comparable at the .4" range at 100. I also believe that my 300 yard groups can be better there is just some "me" in there spreading them out. I will be testing the 75 grain AMAX with varget as soon as I get ahold of them... The COAL w/ C is just my comparator length so you can ignore that. Hope this helps!
