New Guy,

Here is what regulates for me:

1. Siera 235 H4350 81.5 grains
2. Barnes 270 TSX H414 75.0 grains
3. Barnes 300 TSX Load not found yet
4. Wodlgh 350 PP H414 69.5 grains

Comments:
Load 1 and 2 are much reduced. Low pressure loads.

I have not found a load for my 300 grain
bullent that matches the factory Federal.
I'm sure it will be between 75 and 78 grains
of H414 as the 270 load is perfect.

Load 4 is near max.

I like H414 a lot. Its very compact so you never have to compress it. It also produces the least pressure for a given velocity. I tryed IMR4350 and did not like it one bit. To hot. H4350 is good for the lighter bullets.

In conclusion: check your reloading manual first, but starting a few grains below these loads are a good place to start.

BTW, is this your first double, and what is it?
