Im going to no doubt make a lot of you guy's mad at me but, I hunt deer with a 6-284. This is a 284 case necked down to 243 dia. I shoot a 105 gr. Hornady A-MAX, loaded with 54 gr. of RL-22 AND A col - 3.030. This load chronograph's at 3530 fps ave. and the bullet has a .500 BC . I live in Utah and have been an avid hunter all my life. I own a lot of different calibers ranging from a 20 BR up through 300 Remington Ultra Mag. I feel almost embarrassed to say the 6-284 is my favorite deer and elk gun. I'm sure the roof will come down on me, with all this talk about 140 gr. bullets being to small and such but, after 30 year's of killing Deer every year and more Elk than you could load on a flat bed ford, I can honestly say I have never saw any caliber do a finner job at killing animals in their tracks than the load I have worked up for this rifle. Ive got to admit at close range, and at these velocities the bullets tend to come apart, but still leave an exit wound. I think it was P. O. Ackley that refered to this bullet failure as projected missles. When shooting a Deer or Elk sized animal at close range, and watching it drop in it's tracks, it's time to gut. After opening the diaphram the first thing you notice is all the blood coagulated like jello, that is from the shock. Animals killed in this manner dont feel a thing and are dead before they hit the ground.The farther you shoot them the better they hold togeather. If there was such a thing as a perfect load, witch there isnt, Any given bullet would enter the body, preferably at a high rate of speed, and expell all of its energy within the animal with enough forse to break ribs and possibly a piece of a bullet exit wound. Guns that shoot streight through an animal, in my opinion do not expell enough energy in the animal, at times to drop them in there tracks. Well there it is guy's, Ive opened pandoras box, beat me up, I can take it.
