If you were starting from scratch with a blank canvas and were designing your ultimate LR varmint rig for coyote/red fox (Aust). What Calibre would you choose and why? It would need to be an effective one shot killer from 100yds to at least 750yds or greater. Please go into detail with barrel length, twist rate, stock setup and if it can be done accurately enough with a factory rig or would I require a fully customised rifle. Then suggest optically a power range that would be suitable to see these small critters at extended range along with reticle choice. Im not asking for brand names as I think we all have our preferences, just the technical requirements to make an extremely accurate and deadly varminter. /ubbthreads/images/graemlins/smile.gif Regards, Duovid.
