Beware, you will incur the wrath of Jammer 6 asking questions like this

use ~1/2 gr less than what worked with the 180 VLD's....Roger

If my current QL version had the 183 smk in the library I would help. Today is not your lucky day, sorry.

If the 183 smk has a longer bearing surface then QL will show it to generate more psi at the same charge weight as the 180 hybrid.

expiper is right on the money. Around 0.5 gr less might be the sweet spot.

Load some at 59 gr, 59.4 gr & 59.8 gr and see what the target says.
