In this video, the guys from Moss Gun try to kill a Russian Mosin Nagant rifle. I was surprised that they started the overloads with 20 grains of Red Dot, then later used a full case of 4350. My guess would have been that the full case of 4350 would be perfectly fine, while the 20 grains of Red Dot would be far higher pressure. Also, while the load of 2400 they used was definitely an overcharge, half that amount of 2400 would probably be a decent load. That is not a recommendation, by the way.
