Why doesn’t the Kestrel Library have Lapua Long Range and Lapua only lists G1?

[Rsos2313]

Like the title says I was wondering why it’s not there for the use of the custom curve. Only two are listed for mine and a buddies 5700 elite center x and Midas+. Also Lapua only lists G1 and it’s at .172. Next super long range, long range, x-act, and center x all have the same G1 BC of .172. So I guess my only choice is it run that G1 Lapua gives? Any help is appreciated!

Also I guess it’s the same bullet in each of them since they all have the same BC?

The BC is the same. You are correct, Sir, that the projectile is the same in all of the ammo you listed.

You would use the G1 coefficient because the heeled, flat based, projectile used in the .22LR is best computed at the G1 standard.

Hope that helps.

The Lapua ballistics app has the ability to select one of two 22lr bullets for its own calculator. Biathlon is one of them as its visually distinct and is clearly not the same projectile as centre-x, etc. That implies centre-x and everything similar (midas, xact, lr/slr, etc) is possibly same bullet/projectile.

Understood thanks for the response!

Got it. I’m used to eley and for the most part they are all different so I was just curious when I saw that. Eley also lists a G7. So I didn’t know if there was some magic people were doing with Lapua that I didn’t know of haha
