My girlfriend's dad gave her a rifle for last Christmas (I should have such parents – then again I'm not from Texas and her family is; go figure.) And she loves to shoot but isn't completely familiar with all the basics and various trivia and ephemera that tends to build up in the brain of the dedicated firearms enthusiast.
But she cornered me with a question regarding barrel twist rate vs. bullet weight the other day that I couldn't answer. Her rifle is a new Remington XR-100 in .223 and we were plinking away the other day and she wanted to know why the rifle had a 1:12 twist rate.
After I explained how faster twist rates lend themselves to better accuracy with heavier rounds and slower twists work better with lighter rounds, she asked wouldn't a heavier round be more accurate at longer distance (and since this rifle is advertised as a entry level bench rest rifle) why doesn't it have a faster twist.
Guys, she stumped me. Why exactly is 1:12 so common for .223 long guns? I know a heavier round will buck the wind better at longer distances so why not a faster twist straight from the factory?
Help me out here; I have her convinced that John Browning, Gaston Glock and Eugene Stoner and I hang out all the time talking guns and that I personally am the end all and be all of firearms knowledge.
I'd hate to break the truth to her!
