I tried a couple box's of 20, (100BT)in my finlight, they didn't group all that good, 2.5" groups, but much better than the 100gr barns, they looked like a shotgun pattern, I shot one sika and about 20 goats to 200m, worked ok, but I have settled on the 110gr accubond,
Winchester Factory loads are 3100fps, and I was 50fps faster over a mates crony, around 1" five shot groups, Only shot game to about 250m, and one shot and done, the only long (350) range chance I fluffed, by being to smart, and got spotted getting into position, should have shot from ten meters back, but I am sure, I aren't the only one, To have tried to get up to a better rest and been outwitted.
I think that the 110-115gr window, is a good place to be with the 2506, 3250-3150 fps and a .450 bc bullet, 100gr, might as well just use a .243 or 6mm rem,
I got my hands on 200 matrix 125gr bonded bullets to try, loaded up 20 and started development, should get back on that again.
