Reloading for my savage 340 in 222 caliber and wanted to get a very light bullet like a 35 grain. But I don't know my twist rate I've seen people say 340s were 14 and some said it was a 12. This gun will be for ground hogs and similar sized animals and the ocasional stray cat that pees on everything I own outside. Or what bullet would u suggest I was looking for a light bullet in order to push more fps.
