I would ask someone who is competent with GRT if it they can work out the node with your silencer on and no indication of what instrument was used to measure your velocity.

40,1gr en 2535vps by tromp. Ek het jou spoed as korrek aanvaar d.w.s. met MS gemeet.

Met daardie inligting is die teoretiese berekening 39,9gr vir 2534vps.

[Dale SH]

41.8 grains for 2650 fps - 14fps on the chrony.
49 938 psi

If your silencer is not adding any velocity to the bullet.

I think Oom Marius is working on node 6
Node 5 is comfortably achievable as per my post above.
