CCI SV Bullet Length in Kestrel

[USMC22]

I know the BC is 0.120 (G10 per CCI. Anyone got the bullet length?

To get up and running I used AB’s CCI Greentag Info and changed the BC:

Bullet length varies depending on bore diameter.
Tighter bore will swage the fired bullet and make it longer than when it was seated in the brass.

Recovered 22lr bullets fired into a poly-fil trap.
Measured the lengths, no two the same.

So anything the kestrel has listed as bullet length is a guess?

I'm thinking the numbers provided are an average, based on past results.
Just like bullet weight varies, so do length and diameter.
No two cartridges are identical, right?

Makes sense to me. I just try to log everything and make cards for profiles that way if technology does what it usually does I can “rebuild”

It's little wonder that ballistics calculators are not always able to explain or predict the behavior of .22LR ammo, even match ammo.

Unlike jacketed bullets, soft lead .22LR bullets are not exactly uniform. The best lots, which will perform well at all distances, will have bullets that are among the most closely identical.

Bullets for .22LR will vary not only in length, width, and weight, but they will also vary by center of gravity, which is all but impossible to measure, yet very important with regard to performance. Cg will vary between lots and indeed from round-to-round and helps explain why some lots of match ammo have more or less dispersion than others as distance increases.

At significant distance CCISV is not good ammo. Other than a proof of concept exercise, don’t waste time carefully quantifying data on it. Use you time with ammo that costs 2X as much.
