I've been out varmint hunting with my favorite rifles. 243 Ackley Improved, 1lbs Jewel HVT trigger, 28" Krieger Barrel, H&S Precision Stock with aluminum bedding block that I had milled and than steel bedded into the action. Action, bolt, recoil lug, and barrel were trued and tuned perpendicular to the bore. 85gr SGK, 3100fps, 3.5-15x50 NF NSX. Coyote/Dog Hybrid, called in with woodpecker in distress call. 190 yard shot placed reticle on his nose and blew off his jaw and punched into his chest.
223 Weatherby, factory trigger tuned to 2#, Marine Tex and Steel Bedded rifled action. 53gr V-Max 3250fps, 24.5 grs IMR 3031, 2.5-10x44 Vortex PST.
Coyote spotted sneaking away at 100 yards, 1st round in the left hindquarter. Spun him around and follow-upped with a 2nd round through the right eye. Internal pressure popped the left eye out of it's socket. This has been my primary varmint rifle the last 2 years. But, the 243 AI is in the game now!
I guess the pain in his *** wasn't as bad as the poke in his eye!
The 243 AI, I built sometime ago. I Fire formed factory Winchester 100gr ammo while building up enought brass to reload (500 pcs) I recently bought a Redding Competition Die Set and a neck sizing bushing. Worked up a several loads, tested then, and settled on 36.6grs IMR 3031, Coal: 2.627, 3100fps, groups at 100 yards .37 to .45 5 rd shots. So in the past three weeks I've taken 5 coyotes from 100 out to 350 yds with the 243 AI. All one shot kills.
