What velocity do you guess on these? I'm shooting them tomorrow.

[The_Shadow]

Based on the Hodgdons data, they state 1422 fps from 10 test barrel.  You may see 1380 fps give or take...

[Intercooler]

Hardcast as well?

[The_Shadow]

The Hard Cast seems pretty hot but data I found, did state that the velocity was 1200 fps for the 200 Cast

[Intercooler]

Any idea on the Prograde 200gr Hardcast Meplat?

[The_Shadow]

Sorry about that it was added in the post...MEPLAT 0.2650"
