It has been a repeated statement that O/U are very accurate and great at reflex pointing.I have seen many selling in standard rifles cartridges and can't find history of premature death of such O/U's anywhere on the net.Others here will know far more than I ever could research and find.

Question--
If the O/U can stand the pressures of bolt cartridges one wonders if they would tolerate a 9,3 x 74R-286gr loaded 150fps faster.The added velocity would hopefully give deeper penetration and almost 5" less holdover at 300 yd distance with a scope.Why shoot at 300? Why not if you can hit with reasonable accuracy at that distance?

No one wants to hot rod any double and hurt it but it would be interesting to know if the 9.3 x 74R could be pushed to that level of consistent performance in a Double. A 9.3 x 62- 286gr can be pushed to 2500fps in a bolt.Could a O/U handle higher 9,3 x 74R pressures better than a SxS? Has a reasonable limit been found or are pressures lower than they could be and still keep a Double safe?
