Loose Primer pockets 338 RUM
This is most likely a dumb question that I already know the answer to, but here goes. I have been loading new Federal Nickle primed Brass for my 338 RUM. I have been loading 97 grains of RL 25 with a 225 accubond and getting 3300 fps. I know the load is a little hot, as a get a little bit of an extractor shine, but not severe. The problem is that after only one firing on this brass, some of the primer pockets are loose. The obvious answer is to reduce the powder charge, but how much? This load shoots awesome and is an instant lights out with everything I have shot. At the time that I bought this brass, there was quite a bit on gun broker, but now I can't find it anywhere. To the best of my knowledge Federal is the only company offering nickle brass. Does anyone know if the Federal brass is softer than the Remmy brass? I have loaded up some tipped tripple shocks with the same powder charge in some new remmy brass and will head to the range this afternoon to evaluate the performance.
