I've recently found a youtube channel that has been conducting ransom rest accuracy testing with a Gen 3 vs a Gen 5 Glock and many types of ammunition.
I've found it to be very interesting and recommend checking it out. Specifically I found a post by the manufacturer of the Ransom Rest regarding the fact that many semi auto's throw a flyer on the first manually loaded round. I remember Mas Ayoob talking about this in an article once, but I was hoping PF.com may have some ideas of why this occurs? Mas had a name for it if my memory serves me right, but I can't remember what it was... something like 4+1 syndrome or 9+1 syndrome meaning you get a flyer the first shot.
Found this video and read comments wow this is good stuff.. and Jimhans1 is correct but if We can elaborate. We have learned also for basically all semi auto rifle and pistol when you hand rack or even drop the slide release the forces applied to seat the round is not the same as when round fires and when firearm auto cycles. You only see this repeatable in a proper test in a Ransom Rest. Cold bore shot yes but even after 16 rounds it will still do it to a degree. Therefore it is the manually loaded round. Each firearm and ammo combination is bit different but we have seen consistency in this, sometime the firearm and round will throw that first round repeatedly to the 9 clock position some combinations throw it to the 6 or 3. quite interesting some at one inch some 2". We don't see this in revolvers or bolt action. some operators lift machine off battery position in recoil direction to throw first round above target in the berm when testing semi autos. That's only if you can if your berm is high enough. You can in some situations with care, leave last round in chamber from the settling rounds and carefully change mags and continue your test. If you have to change target make sure rest is pointing up and not down range. Care and safety is always needed around firearms of course. This method can also be recommended because we have also had a few semi autos on the last round prints slightly different as well, possibly due to slide locks back and vibration, forces or barrel pressure, or gas cycle. it is interesting. Please comment as well. And I love what AmmoSquared is doing here.I myself like to know what those flyer rounds do and in most cases when you find the right ammo to firearm combo, the flyer, hand rack round can sometimes become minor or miniscule. It still may be a flyer but may not be 1" off it may only repeat at half inch off. And knowing which way that firearm with that ammo may fly to is very valuable info. Thank you great video AmmoSquared
It explains it pretty well, but does this occur even when firing offhand? I can't imagine Bullseye shooters could tolerate the first round from their string being that far off. Any thoughts/info is appreciated.
