Do larger calibers really compensate for bad shots?

[QUOTE="PATGARRET, post: 1706884, member: 69157"] I decided to answer to this permanent question by a real test in SAF, 48 gnus reserved, I selected 3 calibers, a 375 HH (Blaser), a 416 REM Mag (Blaser) and a 458 Lott (Mauser K98) and for each caliber two weight of bullets, light and heavy. This test took place with Mark Dedekind, PH, at a same shooting distance of 200 meters, full side shoulder shot, the objective was to answer to the double question : . is a bigger caliber more efficient, . is an heavy bullet more efficient than a light. THe bullet used were GPA's bullet which forms 4 petals to increase the lethal efficiency with the rear forming a final solid core for the penetration. All the shoots have been recorded and the animals autopsied...great work. The result was : . the key factor is the placement, more important than any other in reasonable limits, . the terminal speed is the second key factor with a blast effect on the animals due to a large temporary cavity, . the weight is determining factor for the penetration, important factor for big 5 heavy animals, Elephants, Rhinos, Hypo, Buffalos... So if I had to resume : . select a caliber with which you are able to sustain less than 1 MOA on [U]field[/U], . select a bullet giving a final speed of 800 m/s at shooting distance, . select a bullet structure allowing a wide temporary cavity with a core allowing a long pemetration, . try to limit you to 2 rifles in order to know their ballistic performances ! In these conditions th 375 HH did perfectly, the 416 REM mag was a little bit slow, I would have prefered the 416 Wby, as far as the 458 Lott is the perfect caliber for the big 5 even if a perfectl shoulder shot in 375 HH is the good medecine for the first right shot on a buffalo's. In these conditions I did 85 % of my animals with one bullet, which is my average rate of success on my present hunter life, the accuracy of my rifles beeing very close to .5 MOA which give a high level on confidence !
