Reviving this almost dormant thread....
I just got a new tool for my load testing.... I've used regular chronographs for velocity measurements when working up loads... this is relatively new to chronographs.... it's an actual doppler technology radar unit. It's supposed to be quite a bit more accurate/consistent than the conventional types.
The best part is that you set it on your bench without having to set anything up downrange. Use it for 10 shots, then stop it. Start it back up later if you wish, without having to wait for a range cease-fire.... (plus it's cool looking :cool:)
I plan to try it out in the next few days.... this pic is what it looks like.... just a generic web pic... I'm much better looking than that guy in the pic... :ROFL:

Nosy question that is really none of my business and you can tell me to mind it if you want to.

How much did that gizmo set you back?

I almost stole it. Brand new, I think they sell for just under $500. The guy I bought it from bought a really nice carrying case (think Pelican quality) and he got the little orange tripod that I guess doesn't normally come with it.. He bought it and never used it... he decided to go another direction... I think he got a smaller one...
Anyway, I got it for $250.
My last chrono, the "old" style with sky screens, cost me just over $100.... so this new whiz-bang one seemed a bargain at 250....

this is what the conventional chrono's look like. You mount them on a tripod, and set them out in front of the shooting bench, about 10-15 feet away. You have to align it with your line of fire and the target, so that you shoot across the top of it, lengthwise, through the skyscreens.
It's not difficult to do, but it takes about 4 or 5 minutes, depending on how lucky you get when aligning it.. minimizes the walking back and forth.. other shooters that are waiting for the line to go "hot" again sometimes get a little antsy....
Also, it is fairly common for people to forget that the line of bullet travel is a couple of inches below the line of sight... when they try to shoot too low over the sensors, they end up perforating the chronograph... that usually makes them not work too well anymore...:ROFL:

So the method you had before worked about the same way as how I checked the top speed of my new electric bicycle a couple weeks ago. Two mile markers and a stopwatch. And your new one works more like a radar gun.

Shooter. I thought that was a Russian thing. The only place I ever heard people routinely referring to guns as shooters was in stalker: road to pripyat - a video game set in Russia. But on that forum everyone was calling guns shooters.

So are the people in that Forum, or at least that thread, mostly Russian? Or what is the demographic for calling guns shooters?

I'm trying to work up a good load in my new-to-me Ruger SFAR... a smaller frame AR in .308. Full .308 goodness out of an AR-15 size (and weight) platform. Good stuff.
Also, an AR-15 in 6.5 Grendel. It's a really neat little cartridge, with a little more power than the 5.56mm.... this one should be great on deer/hog size game... if I ever get to go hunting again..

By smaller frame AR, do you mean short action chambered for 308?

The 308/7.62 by 51mm sounds ideal, why didn't the military go with the 6.5 Grendel to upgrade the 5.56?/?
Cheap brass seekers want to know?!:unsure::unsure::unsure::coffee:

Mr Alexander had a shot at it, but I imagine that big contractors had more sway with the decision makers.
Brass is a fortune though, isn't it?

It's kinda like the previous ACU camo. Things don't always make sense from a practical point of view.

That new .22 sounds like a nice find.
It's about the only ammo left that's reasonably priced for practice. Those h&RS are probably the best looking.
Congratulations on the purchase!

Bill Alexander designed and marketed the Grendel to the US military for their .556 replacement.
It's a longer story and somewhat interesting. I'm just having trouble pulling up the details right now.
Surprisingly, the heavy hitting Beowulf became more popular with hunters and plinkers, so he focussed more on that and his latest cartridge. This video gets into it a little.

Yes... just smaller all around for a .308
The receiver will accept nearly all parts for an AR15....
The AR10 is considerably larger and beefier, which makes for a heavier rifle. My AR10 weighs probably 10 pounds, perhaps more...
My SFAR weighs right around 7 pounds... both of them have 20" barrels....

ah, yes.... I should have known that... my old age is showing... those are really slick revolvers, if I remember correctly the articles I've read about them...
Do those eject spent brass, or just extract it?
