I am looking at buying a like new Browning/FN Herstal custom shop double O/U rifle in 9.3x74 from a private seller. He needs the cash fast, so he is willing to let it go for about $4700 USD. Barrel is 24 inches with a weight of just over 7 lbs. I would like to get into double rifles and like Browning firearm products but a 7lb double rifle in 9.3x74 seems way too light for this round? What would be the lightest gun weight you would go in a double rifle for a 9.3x74? What about barrel length? Thanks.
