Fun with Chonographs

So out to the range I went today, with my new Competition Electronics ProChrono chronograph and my "enhanced" Ruger 96/44, to test some new loads I'm working up.

This is the first time out with the chronograph, and I was admittedly impressed with the ease of setup: put a battery in, put the skyscreen stalks in the slots, turn it on, and shoot through the "V", remembering to aim high to compensate for mechanical offset due to the optics being a few inches above the bore because a low shot that "looks right" through the scope has taken out countless chronographs over the years. Then just read the bullet velocity. Easy, peasy.

I fired five shots for this first test, as I'm working up a new .44 load with a 300gr. Hornady XTP over Titegroup. Today's test load was 8.5gr. of Titegroup, each round hand-measured.

On the plus side, I only had a deviation of 7 feet per second between the fastest and the slowest round in the group, with the slowest being 1053fps and the fastest two both clocking in at 1060fps. So consistency is definitely there.

ON the downside, I was going for subsonic loads, with the maximum velocity sought being 1050fps, and these were just a touch too fast, each one giving off a minor sonic crack that was still comfortable to shoot without ears, but also still audible enough to get the guy on the adjacent rifle range to ask me if I was shooting .22 shorts. I can do better. Next test loads will be half a grain less, and we'll see what we get from those.

The rifle: A Ruger 96/44 lever-action with an integral suppressor done by SRT Arms.

Very quiet with the right loads. And who can't appreciate a silent .44? I just have to do my part and provide ammo that doesn't break the freaking sound barrier, even by a few fps.

Shhhh....It's Range Day

And this time it was out with a rifle that I've had for a bit but not blogged yet for some reason.

This one started life as a basic Ruger 96/44 lever-action rifle in .44 Magnum, a nifty little rifle that Ruger saw fit to discontinue making some years back.

I had to shop around a bit to find one, but when I managed to snag one a couple of years ago, I sent it out to SRT Arms in Arizona and they modified it a bit by fitting it with an integral suppressor tube.

I also added a Bushnell Trophy Red/Green Dot optic to the rifle. It's a nifty little zero-magnification red-dot that offers a choice of four different reticles in both red and green light.

The end result is a rifle that, with the proper ammunition, throws a .44 bullet downrange with the report of an air rifle or .22 short.

With my early test loads using Winchester 231 and 240gr. Hornady XTP bullets, I had it shooting "minute-of-feral-cat" until I ran out of test loads due to my exhausting my supply of Win 231 and my inability to locate any more due to the current hoarding that's still going on.

But now I have a new load, using 300gr. cast lead bullets over Unique powder, and today's test-firing indicated that these start to go supersonic right at 8.5gr. of the Unique, so a bit less powder in the next test batch and I should be right where I need to be to throw these bullets without a muzzle report or sonic crack.

Even with the sonic crack, this rifle can be fired without hearing protection, but without that crack, the report sounds like a loud hand`clap and it's quickly drowned out by the louder sound of the bullet impacting the target downrange.

Yeah, I'm happy with this one. One more batch of test loads to lock in the powder charge and then it's just a matter of adjusting the optic for a 100-yard zero and learning my hold-overs for longer ranges.
