The longer the barrel, the easier they are to shoot more accurately
This statement is 100% true. The problem is.....it's only true in theory, or as they say, "on paper." I have found that I shoot most shorter barreled revolvers better than the longer barreled guns. I have tried to wrap my brain around why this may be the case and here is what I have come up with:
I hold the shorter barreled guns more steadily due to the "center-mass" of the gun being closer to my hand(s). Also, I think this may be happening: What if you flinch/pull/ or jerk your guns, even if only just ever-so-slightly, when you fire them. Most of us do. So, I think of things in this way:
Think of a 10 incher vs. a 5 incher. A bullet will be in the 10 inch barrel roughly twice as long as it spends in the 5 inch barrel. Even though we are talking about minutely small fractions of time.....it is still SOME amount of time. I figure that this small (yet longer) amount of time that the bullet stays in a longer barrel can be enough to throw off your accuracy.
Think of it this way: If during your normal flinch/pull cycle you move the gun a total of 6 degrees. Maybe you are only getting to 3 degrees of movement with the shorter barrel before the bullet is well on it's way down range. Perhaps with the longer barrel example you are able to reach the full 6 degrees of movement before the bullet leaves the muzzle. Couldn't this happen?
I know that I just opened up a huge can of worms. However, while there are tons of other factors that will effect accuracy, I believe that the scenario that I have just stated could hold some validity as well. Sight radius and higher muzzle velocity seem to always come up when people talk about longer barrels. However, I'm not so sure that these two factors add much real world advantages to accuracy as some folks may claim. Each gun shoots differently but some principles seem to hold true.....most of the time.
Another reason that I belive my theory may hold some value is because I notice better accuracy with faster loads sometimes. I feel that the slower rounds are staying in the barrel for a longer amount of time thus allowing more time for the flinch/pull deflection to take effect on the bullet, which may be throwing off it's intended point of impact. Who knows?
TMI? Perhaps. Just don't count out the short barreled revolvers for ranges between 50 and 100 yards. We all have our little "ideas" as to what may be happening when we shoot. No matter what really causes our shots to miss our marks sort of becomes a moot point to some extent. I say this because I'm going to shoot my way and you are going to shoot yours. I saw a guy shoot a small balloon at 200 yards with a FA revolver, with a barrel that was shorter than my pinky finger, chambered in a 22 lr. Even a belt-buckle novelty gun can be shot well at longer distances with the right amount of practice.
Just get yourself a gun that feels right to you and learn to shoot the crud out of it. You simply can't go wrong with any Ruger revolver. This is especially true when it comes to a gun that you intend to use as a shooter.
