The original 0.264 Naturalis has been discontinued and I've not tried the new generation. Info can be found here on Lapuas site: www.lapua.com And they are available from Grafs.
I have not been able to recover a Naturalis from gels, they go right through both gels (>34). You can see from the video, there is very little expansion at low velocities as it goes through.

Even though the length of the Naturalis is acceptable, the weight and low BC render it of limited use in the Grendel. I was able to achieve 2300 fps from a 24 barrel using N530. So the extrapolated MV for the 20 barrel is 2200 fps. Even using Lapuas advertised minimum velocity of 1600 fps, the effective range from a 20 barrel is still only 250 yards. It is likely that the max range is much less.
A three-shot group at 100 yards showed nice 1 MOA accuracy for this large LFP.
