Try asking dixie gun works if they sell bore size conicals for Jaeger you purchased. I noticed a while backthat they keep cast conicals in various sizes. I am veryinterested in your experiences with the Jaeger and conicals and hope you post your experience in the forum. Good luck! Also, you may try pm'ing eldeguello, he owns a .73 Jaeger (in slow twist I think) Or is it sabinajiles?.But I figure they either have experience or know others with experience regarding conicals and the 1:24 twist.
