a recent camel cull was an interesting comparison of these two rounds. the 9.3 was running 300 gn swift aframes, and the man from swift had told me that there would be no difference between them and the 286 gn version. the 375 was using 270 gn woodleigh pp. while both shooting camels in a mob, there was no noticeable difference . both rifles were producing most shots as 1 shot kills, dead before they hit the ground. other shots had no runs after being hit, and dead very soon after. this was a definite step up from previous hunting with a 7mm stw and barnes bullets. the 7 required much more precise bullet placement, and sometimes produced walking wounded. the 7 was easier to hit with ay longer ranges, but was less deadly, giving it no more effective range than the bigger guns. both bullets were FAR more effective than nosler partitions, being reliable with anything like a reasonable shot placement from any angle. the difference between the swift and the woodleigh only beame apparrent when doing experimental shots on dead bodies. a 375 woodleigh pp shot into the back of a head at about 10 yards did not exit. here is a bullet not suited to dangerous game, where the swift is impervious to that problem. the sporting shooters assn of aust has been involved in camel culling in aust., and they tend to use cartridges like 270 and 30/06. these rounds just scratch camels down, particularly with the budget priced bullets they tend to use. personal opinion is that this attitude comes from mental laziness and miserly thinking, and is cruel. just because you are destroying vermin does not mean that they need to suffer any nore than necessary. of course you can easily kill a camel with a shot just behind the shoulder with a 308, but when you have to kill 20 in a mob you have no time to wait for ideal presentation. both rifles produced texas heart shots, and the little guns cannot do that. our shots were from 100 to 300 yards, and bullet performance was equally effective in those distances. they also killes equally as well large bulls and young females of yearling age quartering and side on. i will not bore you by quoting robert ruark. bruce.
