I have tended to have better luck with BR2s vice Fed 210s. 210s aren't bad, just a bit larger groups when I've compared side-by-side. Also a bit slower than BR2s. I have had good luck with F215s on a few occasions though. I had two no-fires with BR2s (one with TAC, one with 8208) when I tested them in the cold. Still looking into that. Although it appears the firing pin was fine. I'm going to try 215s with 8208 when I work up a load for 200 E-Tips.
