I am needing some advice, I did a search on other .30'06 Remington 7400 threads and didn't quite find what I needed. I am going back home for a few weeks to the Texas Panhandle- the Canadian River breaks to be more precise. My cousin has a ranch and is having some trouble with Coyotes marauding his critters. He and I at one time in our youth spent a summer thinning out a bunch of coyotes for his pappy - paid us $20 and found for each set of ears. I used an old Springfield '03 that had been sporterized and had a 3-9X Redfield scope. I made several 400+ yard shots using old 180 gr ball ammo. A good hit was instantly fatal. I suppose I made enough that summer to buy my textbooks there at WTSU that fall in Canyon,TX. There are no seasons for coyotes in Texas- you can kill them any time as long as you have a hunting license - they're considered nuisance pests. Anyway... I was considering a Remington 7400 autoloader carbine (has a 4 round mag)in .30'06 as it is lighter than that old Springfield of Uncle Johns'. I also saw an Eagle Co aftermarket 10 round magazine for the gun in a recent Cheaper Than Dirt Catalog. Anybody got any ideas? I expect the shots will be offhand, prone, and (probably) sitting in brush as camo.The semiauto will help with the running shots and probable follow up shots. I will also pack along my Ruger Blackhawk in 45Colt for the feral hogs that are in the cottonwood copses there. I can taste the bacon and smell the campfire and fresh coffee now as I type this!
