All were groups of 3 fired at 100 metres. didn’t want to go much lower because it would leave quite an airspace in the cases, which by all accounts leads to increased deviation in velocities, which by all accounts leads to less accuracy. All loads with Federal match primers,and 5gns trailboss. For those interested, 20 clicks upwards from a “normal” 100M zero on a scope with 1/4” increments will get you on paper. and there’s not much info out there - frustrating.

I also plan to substitute the BR primers for magnums once I’ve found a load that sits just below the barrier. I’ll get back to you on these when I get opportunity to test. not to mention point of inability to stabilise in THAT barrel.

I’ve loaded up identical loads for each rifle using 62gn Nosler Varmaggedons, and these should be much closer to the sound barrier. I was unsure whether these loads would stabilise in the 1:12 barrel. ?! Wouldn’t need to expand at all for easy day-long headshots. by boy-ohhh-boy were they fun to fire, especially in that massive VSSF! And how about exactly 1/2” at 100M. Each of these loads easily exceed the speed of sound. several ballistic calculators will calculate this for you after the parameters are entered. I regard speed of sound at around 1080, but it’s variable dependant upon conditions. Has anyone tried running subs and supers through the same rifle without modifications and got reliable cycling?I’ve just lately started dabbling in this area. This would be a major draw for me if they did cycle and it would help me overlook the hefty prices for this ammo and pistol.

Has anyone tried subsonics in the pistol and had them cycle reliably? Even being a blowback it is still designed to manage and cycle based on full power rounds and could have problems with a suppressor and lower powered rounds producing less force to overcome the springs? I do like the idea of having 50 rounds in the PS90 where the first 10 or so are subs then 40 supers to follow it up or having 3 or 4 subs in a pistol with 17 full power ones waiting to go.

Even a 240gr 300BLK moving the same speed is hit or miss getting through soft armor and it has over 4 times the energy. 22LR size and power so any vest that can be defeated by a. I would seriously doubt any 55gr bullet going 1,000fps would get through soft armor. Has anyone tried running subs and supers through the same rifle without modifications and got reliable cycling?
