![]() ![]() but it appears anything over 1100 fps would be considered "high velocity" and certainly anything over the speed of sound (1150 fps). I guess you could draw the line anywhere you want. Going back to the 22 LR's development, as soon as smokeless gun powder started being used, high velocity ammo was developed that had a MV of 1200 fps (or more) with a 40 gr bullet. I did find a reference concerning the speed of sound (about 1150 fps) that eluded to high velocity but it was just an opinion. Although there were plenty of references for Standard velocity ranging from 1050~1080 fps with a 40gr bullet fired from a 24" barrel, there were no specific "high velocity" ratings. I did a lot of research trying to find what the shooting industry considers "high velocity". See: Federal Premium Ammunition - Rimfire Their AutoMatch Target Ammunition is rated at 1200 fps so it would be High Velocity, despite what retailers may call it. See: CCI Ammunition - Product Detailįederal also makes Standard Velocity 22 LR ammo (Gold Medal) that is rated at 1075 fps from a 24" barrel. Tactical vs Mini-Mag is a slightly different shaped bullet.ĬCI's "Troy Landry Choot 'um" ammo has a 36gr bullet and is rated at 1260 fps from a 18.5" barrel, which is definitely "high velocity". In other words, the only thing different. This ammo will get the same velocity as a CCI Mini-Mag, which is 1235 fps from a Ruger 10/22 with a 18.5" barrel or 1255 from a 24" locked breach rifle. The above CCI Tactical ammo is rated at 1200 fps from a S&W M&P 15/22, which is a semi-auto with a 16.5" barrel. Why? semi-autos rob a little velocity in order to operate the blow back action plus longer barrels will produce slightly higher velocities. To keep a level playing field, the shooting industry rates all 22 LR ammo velocities from a rifle with a 24" barrel and a locked breach action (anything but a semi-auto) UNLESS OTHERWISE STATED. If you go to CCI's web site, their Standard Velocity 22 LRs are 40gr bullets rated at 1070 fps and 104 ft lbs (CCI Green Tag and CCI Standard Velocity) See: CCI Ammunition - Product Detail Case in point: Midway shows the right velocity (1200 fps), the right bullet weight (40gr), and the correct energy (128 ft lbs) for CCI Tactical but "Standard Velocity" is wrong. If you go directly to the manufacturing source, you will get more realistic data. Khe Sanh, You have to be careful when looking at ammo specs because retailers (such as Midway) often "get it wrong". Many manufactures of firearms do not recommend it's use due to possible damage. Hyper velocity ammo is generally the most inaccurate although not always. Probably best for plinking and informal target work it's not the most accurate since it breaks the sound barrier at least once. High velocity ammo is normally less expensive and cycles semi-autos best. This ammo has a velocity rating below the speed of sound so the bullett won't wobble breaking the barrier. Foreign ammo is used primarily due to its recognized accuracy although cci standard is recognized as good stuff the English and German stuff can be expensive due to the detail taken in manufacturing. The addicts and Olympic competition shooters have found that standard 22'S are the most accurate up to 100 yards. Generally, subsonic ammo is used under 25 yards when noise is a consideration. Hopefully, you won't be "bitten" where you pay $20 for a box of 22's in a quest to get better scores with the best ammo it can be an expensive addiction! Lol-Many of the members here are "target shooters" and have been bitten by the "accuracy bug".
