an alarming discovery

just loaded some rounds, and thought coal looked a bit short.
on further examination, some rounds left over from a prize shoot on sat appear to have a mixture of vld and hybrids in them.
remeasured the throat to be sure, and the loaded rounds have 0.073 jump. (as opposed to 0.015 in)
the vert was not exactly getting my rocks off but was useable.
it looks horribly like a case of grandkids in the mancave!
keep safe,
bruce.

It sounds like an upcoming case of "God help the grandchildren" !! .....or perhaps a new, big lock being placed on the man cave.

So thats the secret of your perfect 15 shot round, 90 score, on Saturday!

YES, YES, YES.
I only discovered this by accident a few days ago. I looked in my HBN bullet coating tumbler and saw a new, uncoated bullet sitting in the top, nice and shiny amongst the other misty looking bullets. After some questions, it seems my dear daughter has been cleaning up the bullets left laying around on the bench (rejects) and putting them with all my other bullets (I keep them in the tumbler until I need them). :evil:
I humbly apologize to Berger for thinking they had been mixing the odd VLDs, Hybrids and 6.5s in the one box for the last year. :-#
What punishment do you have in line for them Bruce. :-s

the problem is that i want them to develop a keenness for shooting, but they are too young and small to use a rifle yet, particularly one with recoil.
evasive action might be the best approach.
obviously powder and primers are locked up, so serious safety issues are not apparrent.
rod,
i am glad not to be the only victim of children.
ian,
i made it clear thet the score was mostly luck. obviously the luck was greater than first thought.
might have to check out more jump in case it is better.
keep safe,
bruce.

I combined my 2 x 10 shotters on Saturday at 700yd, the first with 180 hybs (pointed), the second with 180 VLDs, all other components, including powder charge, identical. I didn't have to change the vertical adj even 1/8MOA between them!

alan,
next test is to mix them in the same string.

Bruce,

Agreed it would be more scientifically valid, but one string immediately followed the other (gap about 20 seconds). I think there are other explanations - the velocity of the VLDs may have been higher (secant vs tangent ogive), and secondly I don't actually believe Berger's published BC figure for the hybrids (unless it was measured after they were pointed).
