Ballistic limits to velocity in a 17 Hornet

[17tbs]

Hello all...

I ran across a South African chap claiming a very high muzzle velocity in a 17Hornet using a proprietary bullet from Perigrine.

I haven't the mathematical ability to determine just if this is even possible using any currently available powder

The numbers I ran for the best powder combination I could dream up say 74,500 PSI in a 17 Remington would possibly net out 4800fps in a 26 inch barrel...

The physics that I am aware of just doesn't allow an extra 1250fps to be gained by using any known loading combination of powder, primer, case or projectile.

He is using a Savage M25...
