Ammo
If you were given a rim fire BR rifle to compete in a match with that you had never fired,and you didn't get to test ammo,but you had your choice of any current mfg.ammo,which ammo would you choose?In short,if you HAD to go completely off your best guess,which one would you put your money on?

James, what part of the country are you in? My local ammo distributor comes to some of the club matches in the region and brings his trailer full of 10X, Eley Black, Lapua and sometimes SK ammo. He usually has 8-15 lots of each and will sell you one box from each lot you choose to test and then more of the lot you like the best. In one afternoon you can find a lot your gun likes. If you partner with another shooter, you can split the test boxes as 25 shots is usually enough to tell you if it is a killer or not.
Over the winter, I tested a bunch of ammo with a factory stock Rem mod 540XR:
RWS R50 - Consistent, no bad flyers but the groups were larger than some of the other best shooters.
10X - 2nd best for my rifle, very consistent - shot in the mid 2's
Lapua Center X - Shot 2nd best group at 50yds. 5sh into 0.165", but was only 4th best overall.
Lapua Midas + - Worst of all the match grade ammo, I have tested, shot in the 4's
Eley Edge - about the same as the RWS. Consistently shot in the 3's
Eley Black - First lot #4 machine shot in the low 3's, 2nd lot shot my best group at 0.128", and recorded six five shot groups fired in sequence that averaged 0.245" for all five. 2nd lot came from #5 machine.
Wolf Match Extra - First lot performed the best. Averaged 0.222", amazingly consistent but I got a 2nd lot and it was in the 3's at best. The first lot was older ammo from 2012. I cannot get any more of it.
SK Std Plus - Shot in the 4's. I sorted this lot into boxes all the same weight to the nearest 1/10th grain, and it shot in the low 2's.
Wolf Match - Shot 3rd best overall.
While the Wolf performed really well, it was inconsistent from lot to lot and the newer lots in no way reached the performance of that first magic lot. All the Lapua/Wolf/SK ammo performed poorly in sub-freezing temps where the Eley continued to do well in the cold, so I am using Eley Black at the moment despite it only being 5th best in the tests. The difference between 1st and 5th was very small. It is wonderfully consistent, and while not the smallest groups, it is predictable and good enough, seems less affected by both cold and wind. And I can get it in quantity. I want to try some more Center-X when the temps warm up as well as some more 10X. PM me and I can put you in contact with my ammo supplier.
