“Ah-ha!” - Moments in firearms.
In the recent thread about the 6.5 Creedmoor my boy uses I mentioned that it was growing on me as a cartridge. But, that statement made me remember one of two “Ah-Ha!” moments in my growth of ballistic knowledge.
1. Growing up, the standard of measurement when choosing or selecting a cartridge was footpounds of energy. Those were the numbers I read and studied. About 25 years ago, I realized that velocity meant more to me in my world than FPE. Muzzle velocity and more importantly......impact velocity was the defining factor that told me what I could and couldn’t do with a given cartridge. And within that......a particular bullet. Knowing, understanding, and operating within the functional velocity threshold of a bullet where it would do what I wanted or needed it to do changed my way of thinking and therefore.......my world.
2. When I started playing more and more with specialty pistols and short barreled rifles, a new mind altering moment happened to me. I stopped thinking of the cartridges themselves and more about the caliber they launched.........at what velocity. For instance, a .308 Winchester isn’t just a .308 Winchester Because a 12” barreled .308 Winchester is VERY different from a 30” barreled .308 Winchester. In fact, by changing the barrel lengths and altering their muzzle and impact velocity, started making that .308 Winchester perform more like a .30-30 Winchester or .30-06 Springfield (for example). Even though it’s still headstamp Ed a .308 Winchester.
A 6.5cal is a 6.5cal but what matters is the velocity you want/need it to travel at. So, you select a cartridge to launch it from in a barrel length that gives you the velocity you desire.
That last one is a real defining moment for me. I now look more at the velocity an overall package provides and less about the headstamp.
None of this may make sense........but it sure changed the way I think and do business.
Anybody else have defined “Ah-Ha” moments in their firearms world?
