Un-explained flier - explained

[brotherdarrell]

While shooting my Rock River Ar this morning I would occasionally have some boolits fail to hit paper @ 100 yds. I figured it was just one of those things I would never know why. While packing up to leave by buddy (whose brand new chrony I was shooting over ) claimed he knew why I was getting fliers.

That would explain it. Thing is I don't remember any gas checks that appeared to be even close to loose when installed. They were seated on a Saeco #221 boolit (Noe)in a push- through die @ .225" and then lubed in a .2255" die on a Lyman 450. I don't see how they could have come off but I think we can all agree they did!!!

Kinda makes you go HUH?

Bad thing about shooting you chronograph is . . . you can't eat it.

[milkman]

I found out pretty quickly that those expensive plastic covers for the Chrony are not reallllly that expensive after all.

[brotherdarrell]

I guess I wasn't clear before. That is not where boolits hit the chrony, that is where gas checks hit the chrony. There was no penetration, on dents. The fliers are from losing the checks.

The factory could have fixed it if you hadn't field dressed it. ;-)

You may have to glue the checks on.

Sorry you can't enter this in my closest recorded chrony contest as the chrony must be hit by the entire boolit not just the gas check. But thanks for trying!

I will try harder next time.:(

How far was the chrony from the muzzle?

[11B-101ABN]

That's EXACTLY the reason I built a steel plate "shoe" for my chrony (s). Now all that sticks out is the rods, and I use wood dowel rods because they still get hit occasionally. It looks like a little steel bobsled with 1/4 inch sides, and a front angled plate 1/2 inch thick.

No matter how many times I see this I still think it is funny as h*ll each time. I guess I am sadistic or something.

[Walter Laich]

Everyone knows someone whose mother's father's uncle's friend's dog that has a great recipe for roast Chronograph, gravy too.

[bosterr]

Mine is the basic Chrony with the read-out in the front of the unit. What I assume was unburned powder cracking the thin plastic over the read-out (probably too close). I made a piece of 1/4" thick plexiglass to friction fit the 3 sided recess at the front. No more problem.

Dear Abby,

Fifteen years and I've never hit my Chrony.

What am I doing wrong?

Signed,

When Chrony-ism is bad for business

[Westwindmike]

A friend made this for my Chrony.

Chrony Condoms made of steel....great idea......the (now defunct) local archery shop should have had one of them....he had 4 or 5 chronies on the wall that had been given "the shaft". Arrows are just as deadly as bullet/boolits apparently. :lol:

[45-70 Chevroner]

I did the same thing to my first Chrony, after that I made a 1/4" Plexiglas shield for the front of my Chrony. A 3/4" X 4" X 6" piece of wood with a 1/4" grove in it and the Plexiglas glued in place works great to ward off gas checks. Personally I have had lots of the old Lyman gas checks ( non crimp on ) come off upon firing and they shoot right into the group all the way out to 100 yards. I don't think the old Lyman checks were intended to stay on. I have recovered a lot of my boolits from a dirt bank and rarely ever found any gas checks still attached, maybe 1 out of 50. On the other hand, Hornady crimp on checks almost always stay on the boolits.

[RoyEllis]

Every time I see a shot up chrony I get a line in my head...."aim low boys, they're riding shetlands"!

[brotherdarrell]

All good ideas on protecting the front of the chrony. I am getting ready to send mine back to get rebuilt as it is almost 30 years old and giving me some suspect numbers. In the mean time I will concentrate on making sure the checks dont come to begin with

And, for the record, I have yet to actually shoot the body of a chrono, yet!! I have hit the wires that hold the sky screens and sent a chrono tumbling down range from the muzzle blast from my 45/70. I do have complete confidence that I will eventually accomplish total destruction one of these days.

Just use Mamasan's standard recipe for rat.

Works for dog and cat.

Serve over rice with nuoc mam.

[JeffinNZ]

Same thing happened to my original Chrony many years ago. I friend fixed it for me.

So much for crimp on gas checks not coming off ah? I was using Hornady.

[jeepyj]

I received my 1st crony for Xmas. I'm wondering how long it will last!

What GC's were you using?

[Green Lizzard]

a walters wad will slap a good dent in one, dont ask how i know

[brotherdarrell]

What GC's were you using?

I was using checks from Blammer, annealed. I have some Hornadys that were a tighter fit, if I remember correctly. This could explain a lot of the blown groups I have been getting, or not?

[yman]

I've nicked my chrono a few times, I think its ducking when I fire. Just been using shooting pistols at it, I think i will move up to a rifle, see if I cant catch it not looking, maybe get it in the shade?

[MT Gianni]

I have shot a lot of Ly checks that were designed to come off and got good groups. The key is they should all come off uniformly. I am not all sure that was the cause of the fliers.

[russs]

11B-101ABN, I sure would like to see a picture of your steel chrony bobsled.

I have only used Blammer's GC's in 30 cal and I found that they were slightly smaller and shorter compared to the Hornady checks. They worked well on some boolits but they were harder to fit on others where the Hornady's fitted better. I use Hornady 22 checks for my AR-15 and am very happy with their performance.

[Captain Capsize]

First time I used my chrony at the range an old timer suggested I use wooden dowels instead of the aluminum sky screen rods. Glad he did, I have shot them twice since. A hit on the aluminum rod will usually shatter the plastic block that holds them. Now I are a old timer.
