Informative article however since i don't currently reload I'm wondering if anyone has something to say about the HSM ammo. Our local gun shop didnt have the rail or base for my action exactally so I modified the rear base to fit however the I'm doubting my work as well as the ammo because I shoot the fed barnes triple shocks just fine. I added a seal of glue around the bases so at least I can see if the move at all. The feel tight but I still have my doubts> I really need to get better bases but until I can find them i'm stuck with thishere's the article "Optimizing Precision And Accuracy From VLD Bullets"
