Possibly a bit of preheat would help? Rapid cooling creating hard spots can be an issue with some filler rod, but ER70S-6 should be fairly neutral in that regard depending on what it picks up out of the base metal. I would think that 350-375 deg would be safe for barrel steel without any annealing action.
I have used up to 500 deg preheats on heavy equipment going by a WPS from Caterpillar welding very hard cast steel ground engaging tools.
