Kynoch 535gr Bullet

The bullet weighed 533 grains.

Kynoch 535gr Powder

The powder weighed 119.7 grains. Not sure what it is, but it looks a lot like the Somchem S365 except the grains color is not uniform. Which means that some grains have more retardent on them than others, which makes for unpredictable pressure.

The bolt binding after one shot at an ambient temperature which is moderate for the field, makes me wonder if the load development for this batch was done during the European winter.
