One Hornady solid .458 Lott was tested, clocking right at 2000 fps from a 15" Encore (!!!!). Bullet went approx. 50" in the wet paper before exiting out the bottom of the stack.

Some observations on this test. No person selected all the loads to be tested; seminar participants signed up with loads they wished to test on a first-come first-served basis. Time ran out before getting to everybody who signed up; among loads on the list that didn't get tested were the .416 Remington and the .445 Supermag. The .600 Nitro and 4-bore there didn't get tested either, in spite of the hopes of some. All loads were shot by same skilled shooter, Kelly Brost of Cast Performance. Procedure went as follows: each shooter in turn handed weapon to Kelly, he then fired two rounds over chronograph then one round through each of the two paper stacks. Volunteers then broke down the stacks to recover bullets and measure, then put stacks together again. Toughest variable to control was getting the exact same shot placement on the beef knuckle every time with paper in front of it. Some hit it dead center, some a little to the side. The beef knuckle joint is one tough piece to test bullets in; if the bullet survives it there isn't much it won't punch through. A couple of bullet failures in the knuckle joint were simply inexplicable; perhaps a reminder that Murphy WILL stike and the hunter had best be prepared for that possibility. Most all of the bullets shed a lot of weight going thru that joint; about the only ones that didn't were the Barnes solid and the Belt Mountain brass LBT flatnose. That Belt Mountain bullet showed no deformation whatsoever; it may well be the wave of the future for big and dangerous stuff. For those who haven't seen them it features a thick "jacket" that is machined from solid brass; a lead core is then swaged into it from the rear. It is currently only available as a 455 grain .510"; others have tested it in a .50 Alaskan and found similarly spectacular results. Kellye Schlepp of Belt Mountain assured me that a 45-70 bullet was on his to-do list. Only downside: at $2 each they definitely aren't plinking fodder.

mccassill,
Thanks for posting the test results. As you can see, I still haven't posted the emails you sent during the week. My apologies, the fish were biting too good on Sunday and I was trying to load up some rounds for the 411 Hawk on Saturday (also ran 2 bears out my yard on Saturday and moose on Sunday!).

I had an absolute ball out there; John is planning on doing another same time next year. I think a lot of folks here would enjoy it.

SHOT THE BUFFALO WITH CAST PERFORMANCE BULLETS AND THOSE WHICH STRUCK BONE COMPLETELY SHATTERED. THIS INCLUDES A HEAD SHOT THAT BROKE UP ON THE SKULL! I BELIEVE THEY HAVE TOO MUCH ANTIMONY, RESULTING IN THE BREAK UP, I PLAN ON TRYING BEARTOOTH BULLETS WHICH HAVE ONLY 3% ANTIMONY, AS WELL AS THE BELT MOUNTAIN BULLETS.
