Yes I agree, its all about bullet placement, which in combat is not always possible. I hunt in Australia with a Custom Sako L461 .223Rem with a old German PECAR Fixed power 8X43mm with a fine cross hair. I hand load Winchester 64Gr Power Point (Lite skinned Game Bullet) @ a Nominal Velocity of 3175 FPS to 3200 FPS depending on which Primer I use at the time? My Game that I hunt are Feral Goats, Foxes and Feral Cats "Of the household kind" that are wild in their thousands in my country from the deserts to the tropics" my 223Rem does it all , it has also hunted Hogs. I Have the 64Grain load as well as the 62Gr Mil spec SS109 FMJ Load Zeroed for just past 250M point of aim ( about 275Yards or there abouts) my favourite shot on goats is the side on shoulder shot and with this zero up close and personal its a case of hold it were you want it to go and @100m I put 3/4 of the goats shoulder above the cross hair and it drills a nice dead centre hole in the shoulder but all of this comes into its own further out given that I have a diner plate sized killing zone with this shot 200m and 250m shots are simply a centre hold on the shoulder and pull the trigger which results in a mild muzzle report mild recoil and a VERY Satisfying Whack as the bullet breaks both shoulders of even the biggest of Goats @ 250m leaving a .50Cal Exit whole on the far side leaving me with my hearing in tact and a very dead Goat EVERY TIME, At 300m I put the cross hair on their spine an have all of the shoulder to drop the bullet into this system works out very well for me but the goats don't like it one little bit. The goal here is to hit bone on the way in, It then takes out the lungs and heart and the shoulder bone on the far side on the way out, It makes for a VERY EASY OFF HAND "ONE" Shot Kill. ** NOTE**now while the Winchester 64Gr P-Point Pill is Not the best grouping pill from my Rifle ( 23" Fluted 1-7 Twist ) what it lacks in its paper punching prowess it more than makes up by being by far the Best Constructed bullet for the job at hand with a 100% kill rate with the fore mentioned shot placement, the 60Gr Hornady HP will NOT exit a average female nanny goat @130m with the same powder charge and 95% of hits are effective 1 shot kills but the Hornady HP bullet comes completely apart under the far shoulder blade, Now the FMJ 62Gr MIL:SPEC Bullet is some thing different and this story go's some way to answering the original thread question as to why it is so that the 223Rem kills every thing but soldiers are unhappy with it? I was given some of these years ago, Live Australia Issue 1991/2 year head stamp these have have hardened steel penetrator in the nose and a lead core in the rear both core meet at the cannelure it is a unstable bullet that is made to fly true by over stabilizing it in a very tight twist if 1-7 Which I have and my rifle was chambered for it "SS109" Deliberately as I was a soldier at the time. I one used 14 of these to shoot a group of 10 young Male goats in a Stalk some of the shooting was done up close and quick just like a combat engagement and the last of that group were at range with a rest to lean on while puffing like mad( the heart rate was sky high) the longer range shots were all good 1 shot each including a full length body shot that went in the left buttock and out the front of the rite hand shoulder at about 150m distant, but the up close shots placed very quickly on multiple targets left 3 wounded goats, Now I had a Delmor I had all 10 goats down( Hunting on foot on my own) having missed two shots in the heat of battle with the up close goats, I had two rounds left and 3 wounded to dispatch( remember we are talking here 62Gr FMJ mil Issue ammo) these three were scattered around a little so back tracking a bit I located the first an dispatched him found the second one was were Id left him and I was in luck he was in the last throws of expiring from a through and through chest shot leaving me with one goat and one round, being pumped at this time and over confident I fired my last round at a range of about 30m with a angled shot from rite rear to front left of the chest, this goat having a quite nasty bullet wound already but still being quite active and bleeding quite a lot upon being struck with my last round simply got up and ran away flat out leaving me stunned, so I followed him up and every time I got near to him he would run again and again. Frustrated I left my rifle behind and followed him further and noticed that this tough little goat was finely slowing some so as I go closer I rushed him and had to tackle him to the Ground and dispatched him with a Knife, the last round had passed clean through hitting nothing vital nor any bone, Now goats are about the same as human in chest density and while I have a good kill rate on goats with FMJ's in other engagements, Even I have had failures in this case shot twice at close range and not fully down but on the run for a while. The conclusion from all of this is this, 1.BULLET PLACEMENT IS ALL IMPORTANT, 2.TRY TO HIT BONE ON THE WAY IN. 3. ALWAYS GO PREPARED THERE IS NO SUCH THING AS A QUICK WALK WHEN THE HUNTING STARTS, 4. IF YOU THINK THAT 1 HAND FULL OF BULLETS IS ENOUGH? THEN TAKE 2 HAND FULLS. 5. YOUR QUIRIE MAY HAVE A STRONGER WILL TO LIVE THAN YOU THINK? AND LASTLY GO WELL EQUIPED AND KEEP SHOOTING TILL YOUR QUIRIE STOPS BREATHING PARTICULARLY IF IT CARRIES A AK47 THIS LAST POINT IS TO OUR MILITARY BROTHERS IN ARMSgun)
