Which way to go?

OK guys, need some advise from the experienced members here.
I shoot bench rest at 600 yds. It is a winter league and the range is infamous for being very windy.
I shoot a 6.5X47.
I have 2 loads that I like from doing development.
First one is a 120 gr and the other is 136 gr.

The 120 gr. numbers are as follows:
37.6 gr. Varget
2899.2 avg. fps
ES-12
SD-5.0


The 136gr:
38.2 gr H4350
2686.6 Avg fps
ES-17
SD-7.4

I like the numbers of the 120 a little better, but logic tells me that the 136 would be better in the windy conditions.

Considering the windy conditions at this range, which load would you go with and explain why please.

Thanks

Shoot an agg with both bullets. If there’s a clear winner go with that one. Repeat the test on a windy day. You might need both at times.

I don't compete but I would agree I'd take both.

Use a ballistics calculator. Enter a 10 mph 90 degree crosswind and check the wind call at 600 yds for both loads. At that range the wind calls will be a little different with wind from one side vs the other due to spin drift, but either way this will give you an idea how much more forgiving one load will be vs the other one.

To beat the wind i shoot 140 and 142 gr. 6.5x47 with H 4350. Tommy Mc

My shooting buddy runs 130 Bergers and H4350. He does
quite well in the wind.
