Anyone have experience with this one?

I'm not, but I'll bet you that Ross Seyfried would know something as he is the Paradox aficionado.

I wonder if the bullet diameter is the same as the RWS 10.3 x 68 Mag.

The Bullet diameter for the 10.3 according to the inventor is .415. The 10.3x60R or 10,3x60R would be a .413 bullet.

My friend Eric Von Schultheiss 10.3 Capra uses a .413 bullet.

Since we can't get ammo for it in America, and probably even bullets who knows.

Eric told me that his 10.3 Capra is only available in his rifles. But if you have a Rossler Titan he can sell you a barrel.

I don't think 10.3mm led free bullets will work in that Lancaster bore since I don't see them compressing to fit through the oval bore (Lancaster rifling).

The 9.6x53mm Lancaster cartridge was developed by Russian Molot and Techcrim companies. It is based on the 7.62x54R case which was trimmed and necked up to accept 10.3mm diameter bullets. The shoulder of the parent case is also moved back. What makes this cartridge a bit different is that it is designed specifically to be used with oval bore (Lancaster rifling) firearms. The unusual designation of 9.6mm with a 10.3mm bullet diameter is because after leaving the oval bore, the bullet’s cross-section becomes oval too with the narrowest portion (width of oval) measuring 9.6mm.

Apart from the oval bore, wouldn't the 405 Grenadier be very similar?
