PBE Felix and Deagle Boltface Patches On Sale Now!

  A while ago we had a thread about high-speed photography and such. I think my friend and I took some curious pictures today, not sure how interesting they will be, but it was enlightening to learn what a DSLR could do in this kind of situation.

The camera in question is an Olympus E-510 with a Zuiko 14-58 F2.8 lens, a little dated and nothing special to begin with. In the midday sun, we were able to get a fast enough shutter to be able to capture bullets. Because of how these kinds of shutters function, the bullets are still quite blurry and faint but they're still visible.

Video is related to explain how the shutters typically work, to explain why the bullets weren't exactly as crisp as one would expect from shutter speeds of 1/4000th of a second, and why they're blurry in a slightly asymmetrical way due to a "rolling shutter" effect.

Also these guys shooting a giggle-switched AR-15 was adorable, great footage as well.

This image is definitely more grainy as we had to close the aperture down quite a bit to have enough depth of field just to get the chance of getting a bullet anywhere near the focal zone. Since we wanted a fast shutter and we couldn't make the sun any brighter, we had to bump up the ISO.

Since we don't have any fancy triggering equipment, we had to do it the old fashion blind luck way, so many images are just brass in the air and like a butterfly off in the distance.

The E-510 can take four or five images per second for a few seconds, my buddy can shoot about that fast, so we tried to line things up. We took turns shooting the gun and trying different angles to get a good chance of landing a snapshot just at the right time, so this led to magdumping over 600 rounds and taking 500 pictures. Most of them aren't really any good, but we did catch a few bullets and had fun emptying mags.

The Shadow 2 really did make this kind of "test" enjoyable. That SAO flat trigger is a thing of beauty.

Don't get it if you want a lightweight pistol. It's a beast of a frame with a pretty small slide so recoil is maximum soft. The stock aluminum grip panels make it thin for a double-stack too, so despite the weight it's friendly for the vast majority of hand sizes. I would highly recommend the SAO flat trigger, but if you don't mind DA/SA the Shadow 2 is still obviously fine. Apart from the small slide, all the controls are pretty much spot on. Being more of a blue-collar person I don't mind the small slide at all.

I think it's one of the best choices for a steel 9x19 double stack fullsize SAO in the more range/target flavor without being a full racegun. There are other great choices as well, but the Shadow 2 has a huge aftermarket and is a common firearm so there's plenty of info out there for tuning it up or fixing any issues.

Thanks for the pics and webms PP, they're rad as fuck.

Thanks mang. I prefer heavier handguns to cover up my shit technique, so I'm fine with heft. Think I'm interested in the SAO version, mainly because I already have a Pre-B with an amazing da/sa trigger, but I've got a buddy that recommends Tanfoglio Stock 3 over a CZ, so I'll have to compare the two personally before I commit

Also, went shooting yesterday, got some new footage

>Tanfoglio Stock 3 over a CZ, so I'll have to compare the two personally before I commit
I personally went with the CZ because it's more common, and seems to have a bit better aftermarket at least where I am. Obviously this is dependent on your personal situation and comparing them side by side is the way to go as the Tanfoglio 3 and the CZ are very similar but not identical.

webm unrelated, just a bit more footage of the shorty SVT-40 in action.

How's the recoil sensation on the shorty?
The full length SVT's recoil is surprisingly mild, but how's the shortening affected the perceived recoil?

>How's the recoil sensation on the shorty?
From my experience, all else being equal (apart from a small weight difference), a shorter barrel firearm with a muzzle brake has a bit less recoil. From what I understand, the gas exiting the shorter barrel is at a higher pressure, and therefore flows through the muzzle brake with more energy, exaggerating the muzzle brake's effect.

This actually leaves me to avoid muzzle brakes with ports that divert gas upwards. In the best of cases, I find they actually push the muzzle down too much when a proper shooting stance is employed. The standard SVT-40 has a long barrel and doesn't have an in-line stock. The ports are cut to divert a bit of gas upwards, but the effect is very small. In my opinion the regular barrel length and the muzzle brake angled cuts are well matched to reduce recoil without pushing the barrel down below the target.

However, when the barrel is shortened to 19", the muzzle brake angled cuts do kick the barrel down. The recoil is even more mild than on the regular length barrel from what I can feel, but I've had to modify the ports on the muzzle brake.

Webm here >>102730 shows the shortened SVT-40 before the modifications to the muzzle brake. The webm here >>105690 shows the modified brake as the rifle is now.

tl;dr it's a very short shooting rifle, even more than before.

You need something with a bit more thump, like a light 18.5" barrel 45-70 firing hot loads that make Garrett's warm-loaded lever action boutique ammo sweat. Bullet torque actually becomes lightly noticeable when flirting with this kind of thing.

Just got some 500 gr Hornady DGX bullets for it, they'll be sitting on probably 45 grains of H4198. Last time I had that going the 500s I was trying were chronying 1800. That load provides 47.6 ft-lbs of recoil at 19.9 ft/s to wake up the shooter through an advanced high speed tactical recoil mitigation system called the "steel buttplate".

For reference, a .308 Win. firing a 150gr bullet at 2800ft/s from a rifle of the same weight yields 15.8 ft-lbs at 11.7 ft/s.

Or just an 8lbs shotgun with a 3.5" chamber.

A few manufacturers make 2 1/4oz turkey loads (984 grains) at 1200ft/s.

Might not look like too much is going on due to my personal enjoyment of such situations, but this does net 70.8ft-lbs at 23.9 ft/s. I've fired more of this ammo than I like to admit.

To compare, a .458 Win Mag from a 9 lbs rifle sending a 500gr bullet at 2100ft/s provides 62.3 ft-lbs at 21.1ft/s of delicious recoil. Close enough for the raifus I go out with.

I bet the muzzle brake helps soften up the Vepr recoil. I went with a 1919 because the stock is in-line with the barrel, you can see here how the muzzle stays relatively tame despite the bare muzzle. It's pretty fun to see those slugs race out past 40 yards too, lookatemgo.

Ignore the xbox scope, it's all I had after the QD mount was kill when recoil made it shit its guts out from under an Aimpoint.
