I have and did. No change for me.
You know guys this annoys me. I will build a load for gun and it shoots great for months, same velocity. Then you buy another can and all the sudden, velocity drops by 50fps consistently. Maybe the rifle. But I have seen this several times. Espeically with RL25.
That is why once I develop a load,I buy at least 5 lbs of powder and usually more of the same lot#.
