Hunting season is underway now across the country. You’ll definitely want to zero your hunting rifle before the hunt, and you need to know how your shots will impact with a cold barrel.
Commonly, hunters won’t have the ability to fire one or two fouling shots before heading out on a hunt. Therefore it’s important that a hunter understands how his rifle shoots with a “cold bore shot”. Both the point of impact (and possibly velocity), may be different with a cold bore than with a barrel that has been warmed and fouled with a series of shots. In this video from the U.S. Army Marksmanship Unit (USAMU), you’ll learn how to determine your cold bore point of impact (POI) for a rifle that just been cleaned, as well as the cold bore POI with a barrel that has already been “fouled in”.
SGT Joe Hein of the USAMU shows how to plot cold bore POI with both a clean bore and a fouled bore. Note that the “cold bore” shot from a fouled barrel was closer to the follow-up shots than the cold bore shot from a clean barrel. This is typical of many factory barrels. SGT Hein provides a simple way to understand your rifle’s cold bore performance. Hein’s advice can keep you from missing that long range shot at that big buck on opening day. A little time spent on the range before that critical first shot will help ensure you have meat in the freezer this season.
Do you find that the crosshairs in your scope get blurry after a while, or that you experience eye strain during a match? This is normal, particularly as you get older. Focusing intensely on your target (through the scope or over iron sights) for an extended period of time can cause eye strain. Thankfully, there are things you can do to reduce eye fatigue. For one — breathe deeper to take in more oxygen. Secondly, give your eyes a break between shots, looking away from the scope or sights.
In our Forum there is an interesting thread about vision and eye fatigue. One Forum member observed: “I have noticed recently that if I linger on the target for too long the crosshairs begin to blur and the whole image gradually darkens as if a cloud passed over the sun. I do wear contacts and wonder if that’s the problem. Anyone else experienced this? — Tommy”
Forum members advised Tommy to relax and breath deep. Increase oxygen intake and also move the eyes off the target for a bit. Closing the eyes briefly between shots can also relieve eye strain. Tommy found this improved the situation.
Keith G. noted: “Make sure you are still breathing… [your condition] sounds similar to the symptoms of holding one’s breath.”
Phil H. explained: “Tom — Our eyes are tremendous oxygen hogs. What you are witnessing is caused by lack of oxygen. When this happens, get off the sights, stare at the grass (most people’s eyes find the color green relaxing), breath, then get back on the rifle. Working on your cardio can help immensely. Worked for me when I shot Palma. Those aperture sights were a bear! The better my cardio got the better and longer I could see. Same thing with scopes. Try it!”
Watercam concurred: “+1 on breathing. Take a long slow deep breath, exhale and break shot. Also make sure you take a moment to look at the horizon without looking through rifle or spotting scope once in a while to fight fatigue. Same thing happens when using iron sights.”
Arizona shooter Scott Harris offered this advice: “To some extent, [blurring vision] happens to anyone staring at something for a long time. I try to keep vision crisp by getting the shot off in a timely fashion or close the eyes briefly to refresh them. Also keep moisturized and protect against wind with wrap-around glasses”.
Breathing Better and Relaxing the Eyes Really Worked…
Tommy, the shooter with the eye problem, said his vision improved after he worked on his breathing and gave his eyes a rest between shots: “Thanks guys. These techniques shrunk my group just a bit and every little bit helps.”

To avoid eye fatigue, take your eyes away from the scope between shots, and look at something nearby (or even close your eyes briefly). Also work on your breathing and don’t hold your breath too long — that robs your system of oxygen.
While some shooting disciplines have moved to electronic targets, most shooting matches still use paper targets, which must have precise dimensions for the particular distance and discipline. If you need correctly-sized targets for specific shooting disciplines (such as NRA Smallbore, F-Class, and 1K Benchrest) check out the links in this article. Precise, dimensionally-correct competition targets are produced by a half-dozen specialty printers. In this article we provide links to the leading target sellers, with a chart showing “who’s got what”. Look for your particular discipline and the vendors will be specified.
Sources for Official Shooting Competition Targets:
AccurateShooter.com offers dozens of FREE, printable targets for target practice, load development, and fun shooting. We also offer a few of the most popular NRA Bullseye targets. One or more of these printable targets should work for most training purposes. However, some readers have asked: “Where can we get the real targets… exactly like the ones used in NRA, IBS, and NBRSA shooting matches?”
All these vendors carry nearly all the NRA High Power and Smallbore targets, including the smaller F-Class targets. National Target has the F-Class and High Power targets, including 100-yard reductions of the 200, 300, and 600-yard military targets.
Here are some of the air rifle, smallbore, and High Power targets at Creedmoor Sports:
Orrville Printing currently sells IBS targets for rimfire (50 yard) benchrest, short-range centerfire Benchrest (100, 200, 300 yards), Hunter BR Rifle (100, 200, 300 yards), plus the official 600-yard and 1000-yard IBS targets. National Target Company also has most of the IBS targets. NBRSA short-range, 600-yard, and 1000-yard benchrest targets are available directly from the NBRSA Business Office.
