Re: 300 win mag. loads?
We need to know the barrel length, twist and animal you are going after, unless I missed that. You say 400 to 1000 yards with a custom, accurized or factory rifle?
Digger has given you the best advice so far from what I read as per the loads I have used and the primer choice for the 300 Winchester mag. He has a factory rifle I believe.
The 190 works very well in a 300 Win mag and bullet choices up to 220 gr work well also.
The 210 Bergers and JLK work extremely well too.
It's hard to beat the Federal primers and the 210 OR 215 will work in the 300 Win mag. I stopped using CCI primers long ago because of hang fires in longrange 1000 yard matches. I know of nobody at Williamsport that usues primers other then Federal or Winchester for match shooting or even LR hunting.
Try the most accurate bullet your rifle likes and go from there.
Check some of the loading manuals and see what they reccomend for a starting load and work up from there.
As an after thought here, If recoil is a factor, the 168 gr Sierra MK may work well in your rifle.
