A 15" encore will get a 900 grain bullet up to a little over 1600 ft/sec with a 600 nitro round. Gotta hold on tight though!

The shorter cheaper 577/450 case with 600 bullets will be more efficient with the shorter barrel and the powder options without filler right?

SafariKid/Boomie- Go all the way to a rifled NEF pistol in 12GaFH. No wussy 900 gr bullets when you can shoot 1100gr slugs. Just put a pistol grip on a NEF and you have the Howdah from Hell! Integral brake or unbraked its still a 16 inch barrel and because the action is so compact not to big to haul around! Probably wont weigh much more than a .600OK Encore either! Just think of the fun you'll have with 1100gr bullets at 1750fps. No one has built one yet! You'll want to get up close, but remember the muzzel flash will be so intense it could cauterize the .73 inch entrance wound!!! Quadracones? Be the first to take out 2 or more Buff with a single shot from a handgun! Now we are talking Knock down power 7K-ft-lbs from a Handgun! At least you know the gun wont blow up! Thats gotta be Max Paynes next handgun! If you see it in the movies look for my headstamp!-Rob

Sounds like a Hoot to me!!
"Quadracone"?! what the heck is that,sounds Fierce!

SafariKid - Go to the 12GafH thread and see what they look like. 4- 250 gr brass conicals designed to disperse rapidly at 1750fps from a 12GaFH case. Oh IT REALLY REALLY WORKS! I need you or Bigdoggy700 to shoot this thing. I Knows my limits!-Rob

I used a .450 Marlin which is very close to a 45-70. Here is what I posted in the lever section.reflex264

Heart and lungs:





bullet # 1 broke the leg bone and got the front of the lungs before lodging in the offside shoulder.
bullet # 2 took out the heart and lungs and lodged under the offside skin, actualy in the skin.
bullet # 3 is an unfired 420gr Crater



I am back. The buffalo was shot at 50 yards after chasing them around for 4 hours from our first contact. I had to shoot it on the move. The front leg towards me was about as far back as it could go during walking when the bullet struck it. The bullet punched through the hide, broke the leg bone, entered the rib cage, destroyed the front end of the lungs, exited the rib cage then entered the front shoulder doing enough damage to stop the buff from walking. It would stand but the leg wouldn't go. I then eased up about 25 yards away and put one right through the heart. The blood stream came out like a fire hose. The buff began to stagger then went down. The second bullet after going through the heart and lungs exited the ribs and lodged in the hide on the off side. I couldn't be more pleased with the performance of the gun and load. reflex264

Note: This water buff weighed 1800lbs. It didn't show any aggression but its budiies did. Fortunately I didn't have to shoot one though. There were some gents there that have hunted cape buffalo and were present during the autopsy. They told us that this animal was as heavily built and as large as any cape buff they had ever seen.

reflex, what was the weight of the bullet?

Is this an actual civilized 45-70/DG thread

BTW the 577/450 case necked to 600 pretty much is a 20 gauge from hell. just uses a 620 vs a 615 slug. could use either bore size though.

Rob, the 600 nitro encore handgun weighs 5lbs 9 oz on my scale. I think I would needto tape up wrists and fingers on shootin hand to try a pistol gripped NEH 12g. from hell handgun!! Cool to think about it though. I think I will let Max shoot it first. The 600 is about my limit in a handgun!

The bullet was a 420gr launched at 1785fps. In my testing before going after the buff the 420gr at 1785 left a larger wound channel than the 550grs and penetrated nearly as deep in my ballistic buff. It penetrated just a bit less than the .375 H&H but with a much better wound channel. Is this load the ideal fight stopper? Probably not but it was certainly adequate to penetrate all the way to the off side skin after snapping the huge leg bone. The heart shot left a hole that shot blood about 4' away from the buffalo. I will find one of the pics that shows this before we cleaned it up for pics. reflex264

Here you go. reflex264

Has anyone used a 460 S&W on buff? If so, what were the particulars? I ask because it has crossed my mind

One more thing that might interest you is a bullet I am working on for use in the .450 Marlin. This bullet wont work in the 45/70 Marlins due to the bullet diameter in front of the case mouth. I haven't settled on a weight as of yet. Preliminary work was with 500grs but I am probably going to try to get it perfected around 400grs. I have the nose profile that I want. This bullet will alow 4000flbs safely from a .450 Marlin. The rifle in the pics with its Brockman extended tube will hold 7 of them. The Jacket is .10" thick and the meplat as of now is .338" which keeps it safe in tube magazines. reflex264

In testing penetration with the 525 cal WLFN shot from the 500 Linebaugh and a 50 Alaskan revolver the addede speed did not increase penetration. The 50 Linebaugh at 1091 FPS penetrated 50 inches of wet pack and the 50 Alaskan penetrated the same 50 inches at nearly 1600 FPS. The bullet from the 50 Alaskan deformed thus the deformation ccaused the bullet to not penetrated farther. Of courxe with a mono metal solid of proper nose shape would penetrate farther at the higher velocity in my experience
The Asian Buffalo that I shot with the 500 JRH with a 425 Grain Flat Point Hard cast with a Meplat that is 78% of bullet diameter at 1380 FPS broke the onside support bone in the shoulder and exited the offside shoulder

I had better luck with velocities in the 1700-1800 range when big bones were encountered in my ballistic buff. As long as wet paper was teh media the 550gr crater at 1500fps was the boss. The 420 at slightly higher speeds left a much better wound channel. reflex264

Here is an example of one of the beef knuckles I use in testing. There is a metal bracket in the front of the ballistic buff that holds the bones in front of the media. reflex264

A beef knuckle shot with a Terminator 12 Guage slug at 1200 FPS




Damage to the wet pack





The Terminator Slug

John Ross is marketing a performance center version of S&Ws 500 Mag that can take a 720 gr. bullet... (Oh, this is a bad idea... but 500s are actually very nice to shoot...)

Ranger Rick produces 700 grain bullets for the .500 and guys have been shooting them in out-of-the-box .500 Smiths. Seems like a bit too much of a good thing if you know what I mean!

If you think a Terminator does alot of damage try a 12gaFH/NEF at 7000-ft-lbs. 1085 gr FP/ reversible HP Darwin slug at 1750FPS. Thats the light load. Same Bullet can be driven over 3000fps from the Borchardt. -Rob

I bet it does do a lot of damage and penetrates a long way as long as the bullet is up to the velocity.
