People thank you for all the input, but you are breaking my heart as I have about 500 Win. Power Points to shoot up. Any suggestion for what powder to load behind them? Thanks all. Cheers NC
What weight Power Point? Do you have an expansion box? I don't often shoot Winchester bullets, any more but I've found that the ones I do, hold together pretty well. Those bullets might work out fine in the Norma.
As far as powder try 76 grains of H4350 or IMR4350 should get you above 2700 fps. I'm assuming that the weight is 250 grains with that load. Also that is a top load. Work up to it.
