has any one used the sierra 155gr tmk bullet ? were they any good ? i have 168gr match kings but have been given a box of the 155gr tmk to try.my normal load for 155 scenar is n140 at 42.6 grains these are very accurate in my rpr.
That should not be too far off. I use Sierra Gamekings 150 grn and used to load 42.0 grns of N140 in my Mauser M03 and currently load 42.9 grns in my M12. I’d load from 42.0 to 43.0 in 2 grain increments somewhere in there should be your most accurate load.
