The Hornady 6th shows reduced loads 2000fps to 2300fps for their 220-225gr bullets using SR4759- 34.4gr start, 42gr max, H4227- 35.6gr start, 38.1gr max(2100fps) and AA5744- 40.5gr start to 47.7gr max. WLRM primer, Win brass, COL 3.340" for the #3705 FP and 3.555" for the #3706 SP.
A few loads that have worked well in my Whitworth .375 H&H are: 46.0/IMR4895/225Cast; 67.0/IMR4064/250SptBt Sierra; 41.5/SR4759/225Cast; and 64.0/IMR4064/235Speer (all with Fed215 primers and Winchester brass).
I've found the 235gr Speer hot core on top of 69 grains of RL-15 to be very accurate and comfortable to shoot. Haven't chrono'd it, but you should get about 2600FPS out of it. Sight in 2.8" high at 100 yards and you should be about 3" low at 250. I'd guess this would kill most medium to medium-large game very dead, and the terminal performance of the Speer hot core should also be good at these medium velocities.
My Charles Daly 375H&H weighs 9.5lbs with scope and has a good recoil pad. Calculated recoil energy is around 26 ft-lbs. This sounds like a lot, but it's less than 2/3 of the energy and recoil velocity when shooting max loads with 300 grainers.
While the Rathcoombe article was a good read...and maybe hydro=dynamic might be a better descriptive word...the use of HYDROSTATIC as a descriptive word used in a specific sense is well understood...and will continue to be used as such...in the vernacular of hunters. It is also the way word meanings are changed or definitions are added to existing words.
Anyone interested might do a Wikipedia search for "hydro-" which refers to water for more thoughts on the subject.
Besides...one man's opinion, even scientific sounding or developed, doesn't really count for much unless it is or has been scrutinized thouroughly by his peers. A look at scientific thoughts over the years proves that conclusively.
Hydrostatic shock means one thing to me. It evokes vivid pictures of many events I've seen and the results of those events. I really don't care what some quasi-scientific person blowing smoke or spouting "group talk" who may not have ever killed a mammal or seen mammals killed...all kinds of four legged AND two...decides to expound on trying to disprove what I know to be true. I choose to call it HYDROSTATIC SHOCK, you can call it what you like, but the results are understood.
Or...am I blowing smoke? ??? ;D :
Oh, sorry, got all worked up....In my older years I tend to pick large calibers with the heaviest bullets for that caliber at modest velocities...they seem to kill quicker and you can eat right up to the bullet hole. Plus you never know what you will encounter out in the woods and a BIG SHOOTER will handle ALL the chores. I load my 375 H&H with 270-300 gr bullets around 2300-2500 f/s. Any loading manual will give you several loads that fit that category...pick the load and bullet that shoots most accurate in your rifle and go enjoy.
Hey Esoxlucius, want proof, shoot a gallon jug full of water , observe what happens, that's exactly what happens when you shoot a blood filled animal. That's what turns your meat to jelly, call it what you want, I call it hydrostatic shock.
NFG echoes my opinions exactly. Rathcoombe argues semantics and definition not actual occurance. I'll continue to call it "hydrostatic shock" also as it does exist. Real hydrostatic shock actually doesn't occur until 1900-2000+ fps impact velocity. However a slower moving larger diameter flat nose bullet or a fast expanding bullet can move a lot of "hydro" out of it's way and cause considerable collateral damage.
One yr. I shot 2 bucks just a few days apart. One at about 100 yds. with a .338 Mag and a 250 Sierra spitzer at 2700 fps. The other from about 75 yds. with a .44 mag Super blackhawk and a 240 gr. jacketed flat pt. Both hits were the same, behind the left shoulder and out thru the right shoulder. The one hit by the .338 hit the ground like he was hit by a truck and stayed there. The one hit by the .44 ran about a 100 yds. leaving a huge blood trail in the snow. The interesting thing was there was more blood shot meat from the .44 hit than from the .338. Just the opposite of what would be expected. While the shock didn't appear to be as much, the HYDRO whatever destroyed the meat even at that low velocity.
You take something still and wet, you hit it with something fast, the energy is transfered through the medium disrupting it. Remember newtons third law? As the bullet slows down the energy has to go somewhere, it goes into the animal.
By definition, it exsists, I have seen it, we all have seen it.
REAL hydrostatic shock depends on surface tension of the medium. When the shock is enough to break the tension holding the tissue together, that is where you see the evidence... the hydro part once again because the energy is transfered through fluid. The bullet is going to damage the liver or lungs much more than it is going to damage muscle, because the surface tension of the muscle fibers is much greater than that of the softer organs, and the organs contain more fluid, better transfering the energy.
Now what you see is evidence of hydroshock, the shock actually extends beyond the damaged area, as the energy drops below the level which will break the tissues tension, you no longer see it as clearly evident further away from the wound channel.
Bigger bullets which carry MORE energy don't do as much damage, because they don't slow down as much, meaning the tissue is not absorbing as much energy. The smaller faster bullets are slowing down more, thus transfering that energy into the tissue.
I've tried the 235 grain speer but couldn't get them to group as well as I liked. Never shot a deer with one of these bullets only paper. Thinking of trying reduced loads with cast bullets for this some day. The 375 is my favorite deer gun and I use the 260 and 300 grain nosler partitions. Overkill maybe, but it gives your hunting buddies something to talk about in camp
