Have a couple of different versions of ammo to test which do you think will work the best?
Judging from the photo, you already have an excellent selection. I'll lay odds that the Eley Tenex Ultimate EPS will do very well.
These are a few more I can think of that aren't in your photo... if you can find them, give 'em a try. All of these have produced excellent results at 25, 50 and 100 yds in various rifles.
Eley Match EPS
Lapua Midas Plus
Lapua Standard Plus
Lapua Polar Biathlon
Lapua Midas M
Lapua Master M
Hope you have good rests... consistency there will make a big difference.
