Re: 270 wsm
Cartridges are designed to do a certain job within a certain range. Most accomplish that as well as can be done and when used within it's parameters there is no need for anything else.
Anytime a "new" or "better" cartridge is introduced it usually does one of three things.
1. It equals the performance of similar cartridges in a smaller and more efficient design.
2. It exceeds the performance of similar cartridges and allows a good cartridge/caliber to become even more versatile.
3. Both of the above.
In each case someone somewhere felt it necessary to improve on something they already had to suit it to their needs. Usually it is to enhance performance by making a cartridge faster, more efficient or so different that it stands out from similar designs..
Very rarely if ever has anyone came out with a new cartridge solely based on affordability. There are no free lunches if you want to have the performance you are used to AND a little more, then you pay for it.
I don't think anyone of us could argue that if our only criteria for owning hunting cartridges in Pa was affordability we could all get by with and never need anything but a .22LR, 30/30win, and a 12ga. Pick the cheapest load for each and all you have to do is get close or closer to harvest any game in the state.
Fortunately there are many, many, many other choices out there to do what we want done. Anyone that is satisfied with what they have is just what they need then so be it. Anyone that has something that already works but is looking for something else either newer, bigger, smaller, faster, fatter, whatever, then so be it.
That is what separates us and keeps the ammo guys in business.
Usually need and want are the two factors that it comes down to when making the decision on what your first, next or last firearm is gonna be. 95% of it is want or we would all be shooting 30/30's in deer season.
Our forefathers didn't bury their guns. They buried those that tried to take them.
