Sometimes things simply amaze me. And this is one of them.
I've got the 395 HH fine tuned in the 375 AM at either 3118 +/-3 or 3128 +/-3 which turns out to be about 3123 with an ES of 16. I can't figure out why 3 shots will average 3118 and awhile later the same load produces 3128 FPS.
At 300 yards velocity difference makes no measurable difference. At 1126 yards it makes no noticeable difference. When the driver is in the "zone" the largest group sizes at that distance are way more than acceptable.
With this fine tuning I was confident I could place the bullet into the media container.
My first attempt was disgustingly unsuccessful as my over confidence allowed me to take a shot in full value highly variable 20 MPH wind. I learned that the 395 HH with my input G& bc of 0.460 does get moved my the wind. No much but enough to just miss my goal.
So that night I cheated. Waiting till about 8:30 PM when the wind died I launched another projectile in that direction.
This one was at 3118 FPS reaching the target media at ~2200 FPS & 4190 FPE.
I took the tools necessary to detect bullet parts and pieces where ever then ended up in the media.
Well!!! So my surprise the hit blew the **** thing apart. I shot into it at 300 yards with the 270 with no adverse effects. However the 338 RUM at that distance busted it up significantly.
I modified it by hinging the bottom so that it could expand like a clam shell upon impact. Filled it with media of the proper wetness, place the plastic lid over the top and wrapped it with a loose fitting bungie strap. All of this to allow it to flex upon impact.
Flex hell... Blew the back completely off, broke off a large chunk of the left side. There was no bullet parts or pieces to be found. The media had sat for a couple of days and had become a bit solid. About a coffee can size area of the right rear remained in chunks. From the front to the rear except for that right rear area the media was as though it went through a blender. I on pick the consistency of the media may be seen on the ground with one of the chunks.
That bullet did more damage at 1126 yards than the 300 Berger @ 2735 did at 300 yards. Steve, are you sure you didn't put some tannerite in those things?
I'm thinkin' that if a frontal shot was taken on a elk at a reasonable distance the hide would be split along its back and brisket.
I'm headed for 1660 yards to confirm bc before going on to a mile and beyond. I'm going to video it this time. I sure would like to see what is happening.
However, I'll first have to rebuild my fixture. Going for more volume this time.
