Hi: I have a Brno 300 series combo with 7x57R over 12ga & 5.56x50R Mag over 12ga. I read somewhere that extra barrel sets were made in 9.3x74 ,375 H&H etc. Does anyone know if this is true and if it is where i can get a set. Regards Dan

With the 7x57R over 12ga you've got the best already. How's it going Dan?

Hi Johnn: Going good. I have since found out that it is another Brno series that has the big barrel sets. I really would like to have a nice 9.3x74 double rifle that would be so cool.The Brno 602 is doing great but i still want to ream it out to a .458 Lott and get a shorter actioned .458 Win Mag. There is a Ruger M77 on CGN for only $800 right now but money is scarce in Mackenzie at the moment.I tried to sell one of my rifles to get it but nobody has any money around here.Good to hear from you Regards Dan
