Daryl,
Thanks for liking the eye catching stock.

The bullet box says 1330 fps and I will chrony a couple of shots to see the velocity from this gun's 26 inch barrels.

Next step will be .405 grain bullet hand loads with VV N133 (avoids chamber pressure spikes, posing less risk when raising pressures above personal experience with the gun) to see the effects of increasing velocity using Chrony to document progress. VV load manual has N133 45-70 loads for 405 grain bullet up to 1900 fps that do not exceed 30,450 psi. We shall see.

With more experience and knowledge, I have 400 and 450 grain NF and Kodiak bullets to load and shoot. At 2000 fps they have proven to be big medicine for elephant, Cape buff, etc.
Again, we shall see just how close I can get to 450 NE velocity without extending the chambers .3 inches to .45-90 length which I already know can run 450 grain bullets at 2150 fps.

All long range musings that might have a future.
