[QUOTE="Ian M, post: 127, member: 25"] Yotebait and you other guys, Just to muddy the waters here is an intersting shoot (I hesitate to use the term "test" as the sample size is too small) I did on a tough media with a variety of premium bullets. No accuracy evaluation, just wanted to see how they compared into a uniform target. I wanted to find out just how tough some of the premium bullets really are. I had five large tightly wrapped bundles of very hard, stiff cardboard sheets, about 8”x10” that I had to get rid of. So why not see how bullets penetrate such a hard medium. Results are impressive, not too scientific, but a heck of a test as cardboard is tough stuff and tells me which bullet to shoot if I ever have to kill a cardboard critter. By comparing the number of sheets penetrated I can determine how one bullet penetrates compared to another. One strange thing occurred, no bullets exited when the bundles where butted one in front of the other. I wanted to get a second bullet, so I placed the five bundles side by side (not butted in a straight line) and shot each one in order. Every bullet completely penetrated and exited the freestanding bundle - maybe the first shot loosened my bundle or something. Firearm: SAKO 75 Barrel Length: 24 3/8” Firing Distance: 100 yards indoor Bundles of 150 stiff cardboard sheets, wrapped in brown wrapping paper, were placed in a single line on the concrete floor, each bundle butting against the next. One .300 Winchester Magnum factory load was shot into each bundle. None of the bullets penetrated a bundle fully. As each round was fired the bundles were rotated forward so that a fresh bundle was always foremost. Shots were fired from the prone position and aimed to strike the center of the bundle, approximately 5” above the floor. The paper wrapping frequently split on a front seam, but all bundles stayed intact. The paper wrapping was then cut open, and the sheets separated to expose each bullet. Care was taken to determine the most forward position of each bullet. Bullets were removed and the penetrated sheets were counted and recorded. The bullets were carefully examined and all visible cardboard was removed with tweezers and a sharp pin. The bullets were then weighed on a reloading scale. Just for interest I added the retained weight and the number of sheets penetrated to get a "score". The little box I am typing in is causing the numbers to go wonky, hopefully they will look better when posted. If not the numbers are: retained weight, % retained weight, # sheets penetrated and the combined weight/sheets number.

(Tactical) 124.8 (75.6%) 091 215.8 Notes: ..all bundles were of equal weight and wrapping ..this test allowed a direct count of penetrated cardboard sheets ..only one round was fired per bullet type ..the TOTAL number is only for interest ..the recovered Winchester bullet was a classic Failsafe profile ..the Sako bullet shed the core and the jacket was tightly packed with cardboard ..the Speer bullet shed the core and was loosely packed with cardboard ..the Nosler peeled back to the inner belt in classic Nosler form ..the Trophy Bonded bullets looked very similar and were excellent mushrooms ..the Woodleigh bullet mushroomed nicely ..did not have factory loaded Barnes or Swift A-Frames - too bad Warren, this is not scientific, just an interesting little comparison that may or may support opinions on what different brands of bullets do.
