Home Forums Hunting & Shooting Ask The Gunwriters MagnetoSpeed Chronograph?

I smell what your stepping in!

At the range where I currently shoot, the area immediately in front of the concrete benches drops down a few feet, which means in order to use chrony I'd have to mount it on a tripod that is about 7-8 feet tall, not to mention if there is any wind, it's likely to blow the whole thing over. The magnetospeed seems like a much better solution.

Agreed.

I don't use a chronograph just to determine velocity to be used for downrange trajectory. I use it to help in finding the best load. ES does make a difference in vertical stringing at long distances.

The chrono also can show when the powder charges are beginning to develop too much pressure before signs like hard bolt lift or marks on casehead show. Occasionally velocity doesn't increase with more powder and that can be helpful too.

I figure if I am at the range why not use all my equipment? I will admit that setting up the skyscreen style chronograph is a bit tiresome but worth the data. Looking forward to getting my SuperChrono for speedy setup.

You can garner much by actually shooting. Throw a few and go. We didn't have any problem plugging soda bottles at 700 yards after we threw a few across the screens.

If you got problems, it will show when shooting at distance, I don't need screens for that.

People love complicating [bleep].

Same guys don`t care what a Rifle cost but moan about spending over $100.00 for a scope!!!

I'm different, and I like it!

Mine should be in the 21st.

so does this thing work on a muzzleloader?

The MS came in today. What a niffty little set-up. I just maybe in business during the rainy days here in the Pac Northwest.

Me too.

Plus, I typically develop loads not so much for the velocity but for the accuracy. If I can hit it, I can kill it. After some development, if I find some similarly accurate loads I will then chrono them to see which is fastest. Or, if one is most accurate, I chrono so I can figure out trajectory and then verify by shooting at distances.

it just seems it used to me much easier to find the time to go through all the hassle of setting up a chronograph. And, many ranges do not want to allow you to set up anything in front of the bench.

I'm looking for a way to mount it on the bench without having to hang it on the barrel. I wish they had included that option.

Someone on here posted pics of his bench-mounted MagnetoSpeed, but a quick search did not turn it up for me. Perhaps someone else can post a link to that post.

Found it: https://www.24hourcampfire.com/ubbth.../8915195/Barrel_Mounted_MagnetoSpeed_V3. The third post.

You live in Montana and have to shoot on a public range? Isn't there some open land somewhere that you can shoot?

My range is the pipeline running across my land, I can shoot 400 yds in one direction and 1000+ in the other direction if I want to drive the target out that far. No dealing with some guy trying to sight in his new remington 783 and bubble pack scope. I put the rifle on the bench, stick the chrono on the tripod and start shooting. I chrono every shot during load workup, if you're not going to collect the data then what's the point of working up a load? Just throw some crap together and plink if that's what gets your rocks off. If you're going to find a consistent load you need to know the velocity/ES/SD etc.

That's my picture you refer to.

I have further modified that setup since posting that picture. The new V3 bayonet lends itself to modification for a bench top setting more readily than my original V1. I don't think it'd be hard to do so. I used a lightweight Sinclair rest I had that was not in use. You can buy that same rest for $99 now. This setup sits just in front of the rifle rest with bench top room to spare. As you can see, the bayonet is fully adjustable and cantilevers out to a maximum of 20". I put the mending plate on the bars so I could break it down & store it in my tackle tray. This rig is a rest, a clamp track for woodworking & a piece of storage bin angle.

I just cobbled together a bench mounted MS. Haven't used it yet, but I think it will work.

Will post photos tomorrow.

I took a Hoppes aluminum rifle rest I've had for years and adapted it to the MS Chrono. I took a 10-24 screw, cut a 5/32" pilot hole thru the base, followed by a 10-24 tap. I had to offset center because of a rib, see photo.

I removed all the MS attachment gadgets, dropped the screw thru the hole, followed by a washer and nut, screwed it into the threaded base followed by another washer and nut. I locked both in place after adjusting to level.

I hacksawed several cuts on the opposite side of the rest, used a cold chisel to break out the pieces, smoothed up the cut with a Dremel. I used a piece of leather to wedge it tight. A steel "T" square sticks to the MS magnet, making it easy to level the device.

I'm going to leave it assembled, just wrap the cord as shown. You can see where I cut a hole to keep the cord from being in a bind.

Haven't used it yet, but think it should work OK. It's rock solid with no wobble and I can adjust the height to accommodate the rifle rest I'm using.

A caliber sized wooden dowel may be nice to make sure the bullet's line of flight will be appropriate. Not sure that will be needed.

Great ideas!!

Have you had any issues with the muzzle blast moving the sensor around? Suppose the base used for mounting needs to be pretty stable?

Good question.

And with muzzle brake?
