The Krag wasn’t a crap rifle, it’s just that the Mauser had the better loading system and magazine. But the US chose the Krag out of a number tested for selection which included Mauser.Again, very interesting, thank you.
And again, the choice of rifle made no difference to the outcome of the war, the side with the crap rifle still won.
(Which leads us to a totally irrelevant and side issue, did any side armed with Mausers ever win a war?)
I think your argument about the winning side and the rifle it has is not the point. It’s one of testing the rifles to assess whether they do what they say on the tin and with the features you want. Eg for the UK, SLR was selected but without the full auto, oh and should we have a scope fitted or these or those iron sights. Let’s test it and see, and by the way how much will it cost.
Having the best rifle doesn’t guarantee winning the war since there are other factors such as the levels of training, skill and doctrine of the opposing armies, but it helps.
In the Austro-Prussian war, Prussia had the better trained army and won. But it also had the breech loading needle gun whilst the Austrians still had muzzle loading rifles forcing them to still stand to load whilst the Prussians could kneel or whatever and had a higher rate of fire. The casualties on the Austrian side was very much higher because of this. Same for when the Prussians went up against the Danes who also had muzzle loaders.
In the Franco-Prussian war, the French had the better breech loading Chassepot but lost because, well, they were French.
In one of the many Russo Turkish wars, Russian infantry was mown down when they came in range and the Turks picked up their repeating Winchester rifles.
Having the better rifle, doesn’t mean you’ll win the war, but having one that is as good as or better than your opponents, meets your needs at the price you want certainly helps.
E2A: After the Krag, the US developed the Springfield 1903, based on the Mauser, for which they paid a licence, and with which they went to war against the Germans with, twice. And when in WW1 they couldn’t get enough Springfields made for their rapidly expanding army, they ramped up the factories that were going to make the P14 for the British but had them chambered for the US cartridge, which was also based on the Mauser action. So the Mauser did win wars. I’m sure there’s likely to be others.
