What is Parallax?
Parallax is the apparent movement of the scope’s reticle (cross-hairs) in relation to the target as the shooter moves his eye across the exit pupil of the riflescope. This is caused by the target and the reticle being located in different focal planes.
Here’s a good explaination of scope parallax. This video has been watched over 790,000 times.
Why is it Important?
The greater the distance to the target and magnification of the optic, the greater the parallax error becomes. Especially at longer distances, significant sighting error can result if parallax is not removed.
How to Remove Parallax
This Nightforce Tech Tip video quickly shows how to remove parallax on your riflescope.
While keeping the rifle still and looking through the riflescope, a slight nod of the head up and down will quickly determine if parallax is present. To remove parallax, start with the adjustment mechanism on infinity and rotate until the reticle remains stationary in relation to the target regardless of head movement. If parallax has been eliminated, the reticle will remain stationary in relation to the target regardless of eye placement behind the optic.
S&W Model 617 now has a 10-round cylinder, but early models were six-shooters.
In recent years, the ranks of first-time gun buyers have grown dramatically. Millions of Americans have purchased their first-ever handgun. With so many handgun options (from derringers to Desert Eagles) many first-time buyers have trouble making a choice. What should those millions of new gun buyers have acquired first? Perhaps it should have been a rimfire revolver. Here is why…
The Argument for a Rimfire Revolver
Some years back, a close relative contacted this Editor. Wanting to get started in handgunning, he sought my advice on purchasing his very first handgun. “Should I get a Glock?”, he asked. “No” was my response. “Well how about an M&P?” he inquired. “Better ergos” I said, “but ‘No’ is still my reply.” “OK, how about a KelTec, they’re cheap…” “Absolutely not”, I replied.
I could tell he was getting annoyed, when he said “OK, Mr. know-it-all, so what handgun should I get?” Calmly, I replied: “Get a .22-caliber rimfire revolver. You will never out-grow it. You will learn sight alignment and trigger control. You can practice with inexpensive ammunition. A good .22 revolver will be considerably more accurate than 90% of the self-loading pistols you could buy. If you get a Smith & Wesson, you will keep the gun for the rest of your life and pass it on to your kids. If you or your heirs ever wear out the barrel or cylinder, Smith & Wesson will replace the parts for free, forever.”
First Handgun Choice — Consider a .22 LR Wheelgun
A very good choice for a first handgun is a Smith & Wesson .22 LR revolver, such as the S&W Model 617. The model 617 is extremely accurate, with a crisp trigger and good sights. Choose either a 4″ or 6″ barrel. The current model has a handy, 10-round cylinder.
This Editor’s first really accurate handgun was a .22 LR Smith & Wesson Model 617 that could easily stack ten shots in a dime at 10 yards. It remains my favorite and most-used handgun. What can we say about the Model 617? The single-action trigger pull is superb, and the accuracy surpasses most any semi-auto rimfire pistol, except for a few, very expensive target pistols. We like the 6″ version for the longer sight radius, but the 4″-barrel 617 is also very accurate, and it balances better.
You can learn all the fundamentals with this ultra-reliable handgun, shooting inexpensive .22 LR ammo. The model 617 is rugged, durable, and can give you a lifetime of shooting fun. Once you have mastered the basics of shooting with a .22 LR, you can move on to larger caliber handguns suitable for self-defense. Below is a slide-show illustrating a S&W model 617 ten-shot, with 6″ barrel. S&W also makes a 4″-barrel version of this revolver. (See: Shooting Demo Video with 4″ model 617.)
Another .22 Revolver Option, the Smith & Wesson Model 63
The current S&W Model 63 is a J-Frame .22 LR with 3″ barrel and fiber optic front sight. The Model 63 is compact enough for comfortable carry and well-balanced. The older Model 63, aka the “Kit Gun”, is an appreciating classic.
