I saw a PH shoot a wounded eland with a Factory Rem 100 gr. 243 in the rear end and the bullet was recovered in the front shoulder perfectly mushroomed, I would not have believed that if I had not seen it...by the same token I have seen the 6mm's fail on deer more than several times??? so I will pass on them myself and use a bigger gun that leaves a better blood trail.
The only reason I wanted some info is that Midway has them on sale for 35 dollars for 500. I typically use Hornady 87 grainers or Sierra 85 hpbt's. Surprisingly I often get complete penetration and good exit holes with these bullets. I have no problem using them within their limitations and consider them quick killers. I shot some 100 grain corelocts at the range a couple of days ago for the brass in my 6mm rem. and got an average accuracy of 1 1/8 inch. Pretty good for factory loads. I wanted to know if hey open fast enough for rib shots to make the quick kills I am used to.
I have witnessed 6 deer shot from a .243 using factory 100gr.Corelokt bullets. All descent bucks,all one shot kills, all with exit wounds, all broadside shots, none fail in there tracks except one who apparantly didn't no he was dead so he kept feeding until he fail over but none ran over 60 yards roughly.
I've heard good reports also on the Rem factory load(100gr). I saw one buck run away but this was due to poor shot placement by the shooter, he aimed for the neck on a forked horn. We never recovered that buck, this was no fault of the bullet but the shooter. I've heard of really impressive reports on the 95gr Nosler Part. but of course you pay more too. sure-shot
