600 Yards with Altaros .22 Airgun

I'm glad you like the video and the rifle.  You probably understand why it is my favorite PCP airgun for many years.

Here is just a few photos from another angle that I made in this summer when I first tested rifle painting. Other photos I have not done yet, since the serial version M24 airguns  we are planning to prepare in the second half of this year . Currently we have a lot of work to complete the semi-auto airgun. Right now its only missing testet each rifle on target for the entire first series of  this rifles and the rifles should be ready for customers. More information about the semi-auto airgun will be given to the newly created section on our website within 1-2 weeks.

.22 LR unfortunately can not by so well used for very long distances because it misses the good consistency of the muzzle velocity.  For repeatable good accurate shooting, is the minimum requirement to + - 3fps. and much more convenient is + - 1.5 fps, and preferably without exception, therefore almost always.

.22 LR  even with the use of the best cartridges (ELEY, RWS), the requirement for such a consistency of the velocity speed does not reach and usually reaching several times worse results.

I have a cople videos  which I need to cut and publish where I measured muzzle velocity consistency for 11 bullets up to 0.5ms (between the fastest and slowest missile there is no difference as much as 0.5ms =  1.64 fps ) and yet a calculated mathematical error, without a shooter error, and regardless of physical reality, which is always worse, it will make a change in impact on a target of 16.6cm (6.5 inches) per 600 yard  for my actual muzzle velocity 263ms. For this reason I want another next prototype M24 improve to reach 290ms or faster muzzle speeds  which will reduce deviation of impact.

For .22LR would be an error affecting this distance, assuming a consistency of muzzle velocity of + - 3ms (about + - 10 fps) about 2m (78 inches). So you would need a target of 2m in order to be a mathematical assumption of a certain hit on the target, only with respect to the muzzle velocity deviation.  If you add a shooter error and the wind that can blow up, you need an even bigger target.

I would also like to mention the SWFA 16x42 riflescope that I got from the USA  before almost 2 year thanks to the shooter who uses the nickname KnifeMaker and I thank him again. This riflescope was a piece of puzzle who missed to rifle to make SWS- sniper weapon system in airgun world. The MIL / MIL system is perfect for the european accustomed to the metric system and the ability to set up to 30 Mrad-100MOA gave the rifle new possibilities. The guaranteed exact repeatability of elevation settings is equally important and works perfectly.  Maybe just magnification16x starts to be a bit inadequate to better observe the impact of the bullet and eventually hit the target.

I got the type for this SWFA riflesope when I watching the great youtube 101 Sniper series from TiborasaurusRex that is  focused on Long range shotign from firearms, but many things can also be moved to the airgun shoting .

Currently I draw additional information from book : Modern Advancements in Long Range Shooting by Bryan Litz where there is also a lot of interesting information that helps me in my development and research  for my projects.

An addition to .22 LR data is true for a fixed speed of about 263ms (the same as I used on video). If, of course, will have muzzle velocity around 320ms, so the difference in height on the target will be much better (difference of about 80cm (31 inches) but still not good enough.

At higher speed I would again be afraid of the transition from supersonic speed to subsonic, which could destabilize the missile. 

.22 LR I'm not shooting, so I'm just starting out from ballistic data and speed differences that were publicly available.

To alamih: thank you for complimenting the appearance of the rifle . Yes, that was the main intention that the airgun looked like a real weapon. In the past, I also made a copy of the Walher WA 2000 rifle in semi-automatic mode and caliber .177. That WA 2000 was the ancestor of the upcoming semi-auto airgun and maybe one day will be the serial production of these WA 2000 .

This is a cutout from a photo of a child's day of 2013, where we every year left for free the children shoot to familiarize themselves with modern airgun.
