Powder charge from SMK to TMK

[1jonathan1994]

In 223 I have 24.6 to 24.9 gr of TAC doing pretty good with 77SMK in hotweather.

I bought a box of 77TMK and wonder what the powder reduction should be considering the tip is eating up magazine length and therefore powder capacity.

Book max for 77smk is 24.8gr of TAC.

Nope. Load and send downrange.

Although my 77gr TMK/SMK load for my precision ARs consists of XBR 8208, they both fly very well with the same charge of 23.2gr.
