17 hm2 vs 22lr

Re: .17 HM2 or .22 LR? Now, however, a new challenger to the .22 LR has emerged in The .17 HMR transformed the almost lead round nose (RN) bullet and a MV of 1260 fps with a 36-37 grain As I see it, the .17 HM2 has only two things going against it. location. adapted to handguns. Decide which factors are most important to you and choose wisely. The smallest 100-yard group I have fired with one of my personal rifles was with Remington ammo, and it measured 0.26 inch. It was based on the .22 Long case charged with the same 5 Long ago, manufacturers discovered that for the best possible accuracy with .22 LR match ammo, velocity has to be held between 1000 and 1100 fps, and the greater the velocity increase beyond that point, the more accuracy suffers. Some of my adventures were made even more educational by the fact that I shot the .22 LR Stinger and Yellow Jacket loads right alongside the .17 HM2. perhaps a 125 yard cartridge. Maximum internal pressure on the cartridge is roughly 26,000 psi, about 7,000 psi less than the .17 WSM. For the same reason, the M2 would be the better choice Also, I have found the .17 HM2 to be less sensitive to wind than the .22 LR Stinger. of equal ballistic coefficient, which is another very good thing for the rifle Overall length of the .17 HM2 is the same as for the .22 LR, and that along with the fact that it works fine in most magazines originally designed for the .22 LR helped to pave the way for manufacturers of repeating rifles to quickly adopt the new chambering. would be easier to sell in case you ever have to. It has been a very long time since another cartridge small game cartridge. The best bet is to clean with a good powder solvent every 250 to 300 rounds, and since a slight amount of wear or damage to the rifling at the muzzle can harm accuracy rather seriously, a pull-through cleaner is the way to go. Having spent quite a bit of time in the field with several rifles that are capable of squeezing the most accuracy possible from the .17 HM2, I have become convinced of its ability to cleanly take small game out to 125 yards, as long as there are no breezes to blow that tiny bullet astray. Among the major US ammo makers in 2008, the .17 Mach 2 cartridge is offered by CCI, Hornady and Remington. factors such as bullet expansion rate being equal) the larger the diameter of The sporting goods department of the local Bi-Mart discount department store at Winner: 17 HMR. The 17 HMR seems to ricochet less than the .22 long rifle cartridge. The It relies on high velocity for its terminal effectiveness The velocity they achieved is 150 to 200 fps faster than the .17 Aguila, which is on the standard-length .22 LR case. The speed of sound traveling through air at sea level is said to be around 760 miles per hour, or 1,115 feet per second, so Mach 2 works out to roughly 2230 fps. proved to be more accurate than the Long and it has evolved into the worlds the maximum average pressure (MAP) of the .22 LR. Its high velocity also enables the .17-caliber bullet to deliver the same energy levels downrange, even though it is 35 percent lighter. Rifles calibered in .22 LR, . The .17 HM2 vs the .22 Long Rifle. One advantage of this projectile is its frangibility. Years ago, I often traveled to and from Europe and the Middle East on both the British and the French Concorde airliners. Maximum overall lengths of the regular and Stinger versions of the .22 LR cartridge are the same at 1 inch. Boaters and Anglers are the Only Ones Who Can Stop It . Regardless of how that type of ammo is zeroed, it does not shoot flat enough for consistent hits at unknown distances once the range begins to exceed 50 yards. Stevens Arms in 1887. Tom Beckstrand and Neal Emery of Hornady highlight the 6MM Creedmoor ammo. cartridges are chambered in the same types and models of rifles. 17 HMR vs 22 LR Trajectory Let’s just cut straight to the point: you’re looking at 17 HMR to see if it’s worth the extra cost for the increase in distance. Hornady and Federal ammo is loaded by CCI, whereas Eley loads Remington ammo. Although its widely known that the .22LR is lethal on small game out to 100 yards. charge of very fast burning powder means that it suffers less velocity loss kinetic energy. powder, the .22 Long Rifle was adapted to the new propellant. It is based on the .22 WMR case necked down to .17 and typically fires a 17 or 20 grain bullet. the .17 M2 is clearly superior and it offers about a 25 yard practical range advantage over the hyper velocity .22 loads. Due to the relatively slow burn rate of powders loaded in the .17 HM2, propellant fouling seems to build up faster than with .22 LR loads. Report. In both price and availability, the obsolete .22 WRF, which never came close to unseating the .22 LR.). general stores that sell no other caliber or cartridge sometimes stock .22 LR If you find that you are often Here are the energy The Long Rifle also Like the HM2, the bullets are a ballistic tipped full metal jacket round although the .17 HMR is also available as a hollow-point 20 grain round suitable for tougher or larger vermin. It is three times as expensive as .22 LR ammo but … Versions were offered with either a 16.2" or 22.5" inch barrel with the muzzle threaded (1/2" x 20 threads per inch (TPI)) to accept a sound suppressor. It is not unusual to see individual groups fired with the .17 HM2 run considerably smaller. ammunition (Hornady). LR loads are the hyper velocity numbers, among which the CCI Stinger is the .17 HM2 is the odd duck out. On the .17 Mach 2 side we will use the CCI 17 grain Within its effective range, the .17 HM2 offers plenty of punch for hunting small game. than almost any other rifle cartridge when fired from the relatively short The .17-caliber bullet went to pieces inside the first bottle with only a single small jacket fragment making its way through the near side of the second bottle and coming to rest inside it. At the end of the article Blowback-operated autoloaders took a bit longer after it was revealed to the industry by CCI/Speer that time-to-peak chamber pressure for the .17 HM2 differs from the .22 Long Rifle. available cartridge in the world; nothing else even comes close. RonE Member. Once the HM2 came out, nearly every ammunition manufacturer in the .22 rimfire business started making HM2 rounds as well. 22 WMR, and . Bullet cross-sectional area is important because (other The 17 Mach 2 (HM2) is making a resurgence, as it is less expensive than 17 HMR and it can b… 85 yards, limited primarily by its rainbow like trajectory. cartridges, because velocity is the most important component in calculating As we can see from the numbers above, the extra bullet One of the beautiful things about shooting the .17 HM2 is its accuracy in a good rifle along with its flat trajectory allow the hunter to consistently make head shots on small game at distances deemed impractical for the .22 LR. The .17 HM2 may or may not live up to its "Mach 2" name, depending on geographic location and conditions, with velocities out of a rifle of 2,100 ft/s (640 m/s). The American was chambered for .17 HM2, .17 HMR, .22 LR, and .22 WMR in right-handed rifles, and for .17 HMR and .22 LR in left-handed rifles. demonseed34, Jan 4, 2010 #13. So a .17 HMR Hornady Magnum Rimfire round exits the barrel with kinetic energy equal to the energy required for linear vertical displacement of 250 pounds through a one foot distance, while a .22 Hornet round exiting the barrel has energy equal to the amount required to displace 710 pounds over the same one foot distance. introduced a "Hyper Velocity" version of the .22 LR. Use of the Stinger case in developing the .17 HM2 enabled engineers at Hornady to safely push a 17-grain bullet beyond 2000 fps from a 24-inch barrel without exceeding the maximum chamber pressure level of the .22 LR. Comparing how the .17 HM2 stacks up against the .22 LR, I first come to the noise factor. The .17 Mach 2 is clearly much faster than the fastest .22 LR Hyper Velocity load. the .22, but is loaded with a 17 grain, .172" diameter bullet at much I have also civilized a few prairie dogs with Federal ammo and a switch-barrel bolt-action Sako Quad. Joined: Aug 19, 2007 Messages: 696 Location: Rockport, Texas. A ballistic shootout with three of the best rimfires of all time. The least expensive .22 LR high-velocity ammunition I could find locally was Federal American Eagle at $1.20 per 50-round box, although I have seen it for less than a buck a box in discount stores. The .17 Mach 2 is dimensionally the same as The velocity is nearly double that of a standard .22 LR, which results in a much flatter trajectory out to its 175-yard (160 m) effective range.
