I've only fired one shot with my BPS10 with lead #4 buckshot using a .705" Terror choke. The pattern seemed to be pretty good, but one shot is not enough to judge the load and choke combination.
You may find the .695" choke too tight for #4 lead buckshot. I tried a couple of shots out of my Nova using a .675" Terror choke that performs quite well with steel BBB's, but it gave terrible patterns with the lead #4 buckshot. A modified, .705", in the Benelli system, gave considerably better patterns.
Using factory Browning extended chokes, I got my best patterns in my BPS10ga. with lead #4 buckshot using a .735" choke. I think chokes that are too tight for large lead pellets deform the pellets too much to produce good patterns.
If your choke doesn't pattern well, try dropping back to a Improved Modified (about .750") or a modified choke, and see if your patterns improve. If they do, your .695" is just too tight for that pellet size.
But, like anything else in pattering shotguns, you might be fortunate and your .695" may pattern them well. Just don't assume that because it patterns small lead shot tightly that it will do the same with large lead shot. It normally won't.
