Hi, I only have one rifle in the Denver, it is a custom KMW .308 rifle with a 24 inch 1 in 11 twist Krieger barrel. I have used it to shoot prairie dogs using 168 gr SMK by Federal, however, the PD's do not EXPLODE like the ones in Prairie Dogs Begone. I contacted Hunting Shack if they can load me rounds for my rifle using 110gr Vmax heads. And they said that they could. Will this make a better impression on the prairie dogs? Can I use this on my rifle? What bullet loading would you suggest. pwder, velocity, etc. I know that the .308 is not really a varmint load but I would like to make the most out of what I have. I would appreciate any help that you can give me. Also, I would like to use this rifle to hunt elk. I was told by my gunmaker that it will do the job below 300 meters. Can elk be approached to as near as 300 meters? What ammo do you recommend? I do not have access to reloading so i will need it to be either commmercial ammo or semi custom like HSM. Thank you.
