Chrongraphs

[krktractor]

What is the most accurate cost effective Chrongraphs out there I'm goin to buy s new one and need some help on which one you guys think is a good one. Thanks.

+1 on the Magnetospeed but......

 

[mikegaiz]

Ok as long as it is not part of load testing development. Oehler 35P sets the standard., but that is just my opinion.

 

[JimPag]

Without a doubt, you can't beat an Oehler 35P or 43.

 

[Ledd Slinger]

Yeah I've read a lot of experiments and articles that prove the Magneto speed can, and most of the time will, change a rifles group size or point of impact at longer ranges when it is mounted on the barrel. But that's not my personal experience so take it as you will.

I have a Chrony Beta Master. It's ok, but no Oehler. I get error reads here and there. Gonna order the LED light kit. Supposedly a must have for the Chrony brand to make them really reliable.

 

[krktractor]

So If I'm load testing I need the oeer would be the way to go

 

[krktractor]

Damn spell corect

 

[ballistic64]

The new LabRadar coming out sure looks promising for about the same cost of the Oehler. But I hate buying a first generation anything.

Here's a prime example of what the magneto speed does to groups attached to the barrel.
This first pic is with the magneto speed on at 500 yards.

Now here's the same load without the magnetospeed same distance same sitting.

This is from a barrel that's 1.250 straight so just imagine what it do to a smaller barrel and lighter gun.

I'm new to the magneto speed but any logic is going to tell you it's going to effect the harmonics of a barrel.

 

[Ledd Slinger]

Yep. That's what I've seen and read about the magneto almost everywhere. No way a person can load test and chronograph at the same time with it on the barrel. That would be really annoying IMO

Nice groups by the way

James - was there also a muzzle brake removed when the group with the magneto was shot?

 

[krktractor]

Well sounds like a oehler is in order. Does the sunlight and shade effect it like the others too or does it not matter. The one I have is picky

 

[effendude]

I have no doubt the Oehler is an awesome chrono. They really do set the standard for performance.

I will tell you that if you shoot at a range with others, public or private, eventually you will buy the Magnetospeed. I literally can assemble and attach the unit to the barrel in less than 30 seconds. I can fire my rounds, save the data to memory in no time at all without inconveniencing others or tempting them to ask to send a few rounds over my chrono too. No tedious time calling the line safe, aligning screens, tippy tripods, tangled cords, etc.

Yeah that's why I was so interested in the Magnetospeed and read as many reviews as I could find. The speed of set-up and convenience is second to none.

The standard style of chronographs are a pain to set up and align with the target/barrel but you get used to it I guess. I think it's pretty obvious that the magnetospeed interferes with the muzzle blast and changes things on the target. I read some reviews where the magnetospeed was actually making groups tighter than the rifle would shoot without it mounted, but whether a negative or positive change on the group, any change is not a good thing because it is not how the rifle will actually shoot on the firing line or in the field. It really is an ingenious design, just wish they could come up with some way to keep it from interfering with the muzzle blast and effecting POI or groups sizes.

Yes the brake was removed when I was using the magnetospeed.

 

[Ledd Slinger]

Probably would HAVE to remove a brake or there wouldn't have been any more magneto speed to use

Another disadvantage of Magnetospeed for the list I suppose...

So was the group without the magnetospeed fired without the brake as well or did you screw it back on?

My testing seems to differ from yours. I did a comparison at 600 yards with my 6mmBR/1.25" x 30" Brux barrel with and without my MagnetoSpeed installed. Overall the weather conditions were pretty good. I measured the target/group on my computer using the On Target Precision Calculator Target 2.1 Program. The 4 shot group without the MagnetoSpeed installed measured 1.346" width x .540" height. The 4 shot group with the MagnetoSpeed installed measured 1.390" width x .506" height. The group with the MagnetoSpeed installed was 4.281" down and 1.291" left center to center from the group without the MagnetoSpeed. Again, this was at 600 yds. To me the group size in this test with and without the MagnetoSpeed installed seemed consistent. I made no sighting corrections when I shot these groups. Personally I do not care about the Point Of Impact shift as I do not shoot for score with the MagnetoSpeed installed and through my testing it has shown to me that it does not affect my group size when doing load development. Also I have found that if you want to the POI is easily correctable through scope adjustment.

 

[Ledd Slinger]

Snakepit,
Like I said earler, I have read reviews where the groups were tighter with the Magnetospeed mounted. Have also read reviews like yours where groups remained pretty consistent but POI would change. Something messing with how a gun actually shoots is never a good thing in my opinion. But your satisfaction is not my decision. Glad that the Magnetospeed is working to your liking.
