BC of the Kindler 30 Gold is .270 if I'm not mistaken.
Blaine's using a .100 short .17 PPC he dubbed the .17 DT (dog terminator). Getting a tad over 4,000 with Todd's 30's in it. He killed 80 coyotes with it this winter, including a few long ones, but the long ones are definitely not the "norm". He's using a 10 twist too, by the way. Was talking to him on the phone last night, gots me all worked up to build a large case small caliber for predators and medium long range chucks (400 - 600). Dan Clements' .17 Predator gets the same kind of performance on a .378 bolt face in a repeater too. I've REALLY got a woody for one of those. Same old problem for me, too many wants and too little cash!
But getting back to 500 yd. p-dogs, in good conditions, just damn near any accurate rifle will do. When the wind gets bad, damn near nothing will!
