Did some fiddling with primers today. Using 185 TTSXs and 180 BTs, and TAC and 8208 XBR and then loading each with Fed 210s and BR2s. Found that with 8208, groups were the same regardless of primer. But with TAC, the BR2 groups were much better with both of the bullets. Surprised me. Just tossing this out there to see if anyone has found anything similar.
