I am looking into the .20 BR for a long range varmint gun and was curious about the twist needed to stabilize the Berger 50 gr. bullet. If it can shoot them so much faster than the other 20 cals. does it need a 1 in 9? also has anyone shot critters with this bullet? I am not a fan of match bullets for varmints but there are some designs that open up well, so I thought I would ask.
Thanx
