I just bought 700 mountain rifle in 7x57 that was made in 1989. From what I have seen is that because the 7x57 is such a historic round, and there are so many old guns chambered in it factory loads and load suggestions are rather anemic because the older guns can't handle the pressure.
I was looking through Hodgdon's Reloading magazine and came across the following loads for 140s. The left side is the minimum and the right is the max. To me, it seems that max load is still light, and I could push this more in a modern firearm.
My goal, which I think is doable is a load that pushes a 140gr bullet around 2,800fps. Certainly I'll work up to it, but do you have any pet loads that you love for the 7x57?
This should give you all you need
