A quick Crony test

I went to the long range today as the short one is closed due to fire risk :(

The long range is a 90-95 km round trip, much further than the shot range :XD:

My new Magneto Speed 2 Crony showed up yesterday so I thought it would be a good idea to try it out.
I pre-ordered it just before the Accoustic ones showed up......bugger or not....

I thought it would be a good idea as I could use it when ever I wanted ie shooting rocks way up a hill, etc.

As you can see by the photos sometimes it's a real misson setting up a crony depending where you are shooting.

I had the Magneto Speed on the muzzle, then I dusted off the F1 (that I haven't used since I got the 35P) & put it in front of the Oehler.

The speeds were a bit erractic as I expected, different loads & it was in the bright Nelson sun :)

I was shooting a 6.5-284 over them.

MS.......F1.....35P
2920....2949....2959
2969....2962....2961
2840....2814....2813
2845....2842....2837
2855....2854....2850
2870....2876....2861

They all were pretty close with the 140s

The 300s out of the Edges were a different story, I didn't use the MS only the F1 & 35P & only recorded a few of the starting loads.

F1.......35P
2754....2736
2756....2740
2750....2731
2757....2732

& just to make a good day even better the 3 rifles behaved themselves nicely especially the new Edges :D

That magneto chrony looks the bizzo !!!

Now you just need an acoustic and ced :D
So goin on that and my results previous 2 days it would be fair to say the f1 needs bright sun to be close ?

With the high price of decent chrony's it's very tempting to have a crack at making one! That magneto one should be relatively easy cheap to make (with one major change as to not breach the patent while also improving the system) :XD: First thing's first, better find some free time... haha

well now we just need to compare them with a super chrony .
i could possibly lend you mine if your keen?

Those results are all pretty close, and I'm not sure which one is best? But it does show me that the old $150 F1 is still a good yard stick to measure by eh.

Mine went from 3180 to 2800 one day apart with same load, one bright sun other very overcast . Bright sun was fairly accurate at the fastest and overcast was slow
