Prompted by a comment the latest Rifle Shooter Magazine which I picked up on Monday as two hour wait at Luton Airport. One of the writers made a comment to the effect that a hunter from 100 years ago would be totally happy using pretty much any modern rifle, whereas give him an iPhone or other piece of digital technology, he might be pretty amazed. Worth pondering on.
Thinking about it not a lot has changed. Bolt action is basically the same, although modern rifles might shoot a little more accurately out of the box. Certainly optics are better, and possibly a bit more reliable, but WW1 era german optics certainly allowed shots at well beyond normal hunting ranges and at night. Straight pull rifles were turn of last century - Canadian Ross being a good example.
And as for ammunition, it will be pretty much the same. Indeed all our calibres were already well established. 22lr, 6.5x55, 7x57, 30-30, 30-06, 375 H&H, 470NE, 45-70etc all still going strong. In the 22cf and 6mm, cartridges such as the 22 Savage High Power, and 244 Holland are now somewhat obsolete, but 50 year old 22-250, 223, 243 etc fill the same niche and offer pretty much the same ballistics.
I suppose the one big change in the last 30 odd years is the wide use of polymers. Many rifles and shotguns from the turn of the last century are still in use today. I wonder if polymer built rifles will still be in use by our grand and great grand children in 100 years time. Not sure if many of us on SD will be around by then.
