As Reactive Targets, Billiard Chalks Are Fun and Challenging

AccurateShooter Billiard Chalks targets

Reactive targets — whether balloons, steel gongs, or clay birds — always add fun to a range session. But precision shooters may want something more challenging (i.e. smaller) than a clay bird when shooting inside 300 yards. For a change of pace, try shooting at inexpensive pool cue chalks. Less than 1″ square, these will test your marksmanship skills.

Pool Cue Chalks — Cheap, Fun, Dramatic
If you’re looking for a small target that makes a nice big cloud of color when hit, try pool cue chalks — those little blue cubes you use to dust the end of billiard cues. Measuring about 7/8″ per side, billiard chalks make very challenging targets at 100 and 200 yards. When you hit them, if you nail the circular “dimple” in the middle, they disintegrate impressively, tossing blue “smoke” in all directions. Billiard chalks are inexpensive. You can buy a dozen chalks online for about $3.00 — just 25 cents each. And the prices drop with more quantity. One gross of chalks (that’s 144 pieces) costs just $19.95 at ozonebilliards.com.

To see actual hits on chalk at 100 and 200 yards, watch the video above. (WARNING: Soundtrack is loud and advertisement may play before movie.) The movie-maker, Phil of the Random Nuclear Strikes Blog, cautions that: “You’ll notice (in the video) that some of the hits are ‘wiffs’ instead of ‘poofs’. If you look at the picture above, you’ll see the 1/2 inch dimple in the cube face. If you don’t put the bullet in that dimple, it’ll ‘wiff’ on you.”

CMP Armorer Explains Garand Headspacing Procedures

M1 Garand head space

Garand matches are among the most popular and well-attended of the CMP competition disciplines. When obtained directly from the CMP, Garands are fun to shoot and affordable. However, with these classic battle rifles, you need to ensure that the headspace is set properly to ensure safe function and good brass life.

Garand WWII posterIn the archives of The FIRST SHOT, the CMP’s online magazine, CMP Armorer John McLean has written an excellent article entitled: “Everything You Ever Wanted to Know about Checking M1 Garand Head Space.” We recommend all Garand shooters read the article.

McClean explains: “Excessive headspace will cause the brass to stretch more than it should and increases the likelihood of a case failure. Insufficient headspace may contribute to slam fires, light strikes on primers, misfires and more wear on parts due to the additional force needed to chamber the rounds.”

Garand Head Space Gauges
McClean writes: “Both Forster and Clymer make fine gauges but we have found that there are differences between the two companies’ gauges that make the Clymer gauges best for use with the M1. The headspace that the original manufacturers of the M1 considered correct can be determined by checking new or nearly new rifles that we have here at CMP. With that information we have determined that Springfield Armory and the other manufacturers of the M1 used gauges that were very close to the Clymer dimensions… and therefore we use, and recommend using only the Clymer gauges.”

How to Check for Proper Headspace
In the article, McClean goes on to show how to properly use the “GO”, “NO GO”, and “FIELD” gauges. You’ll want to read the Complete Article. One of the important points McClean makes is that the ejector can affect headspace reading. Accordingly, “the bolt must be disassembled and the ejector removed, or clearance notches must be made on the headspace gauges so there will be no contact between the headspace gauges and the ejector.”
