after shooting the Accura V2, the lower velocity is caused by the flash channel clogging up.

First shot on a bore that had 10 shots through it from yesterday and a non cleaned Flash channel shot 1997 FPS, Second shot with the channel cleaned, 2050, Next shot with it cleaned again was 2075. The 110gr BH209 load with the 250's ended up with a 32 FPS spread so i will have to tinker with some loads in that rifle. Avg velocity was 2041.
