If you have a fast twist, 1:8, a very good load is 36.3 gr H4350 behind a 105 Berger, seated a few thousandths in the lands.

A 1:9 twist MIGHT handle the 105 also.

I have 2 guns chambered 6-250. Winchester 760 works really well in that case and also the .243 & 6mm case. Depending on bullet, one rifle uses W760 and the other likes WCC844. Bullets are 55-70gr. These are strictly varmint guns and 200yds is nothing, you don't need heavy bullets for that distance.
