This is most interesting , Mark Hunter. Out of curiosity what choke do you use ? My s686 from Beretta is a full choke over a modified choke .
Sir, mr Rahman,
First I must tell you that beretta 686 silver pigeon was my first choice. However, when I was buying a shotgun with purchase permit in a pocket, there was only Beretta available in gauge 20 in local shop. The dealer was promising soon delivery of gauge 12, but it never arrived.
My backup option was browning b 525 O/U, 12 ga, and when my purchasing permit was about two weeks to expire I went for browning (and with another dealer).
It has: chromed backbored barrels,
removable chokes, single selective trigger (of inertial type), ejectors, and chambered in 12/76.
It was delivered with 3 removable chokes:
- Full
- modified
- improved cylinder
And with some field experience, and with some training on clay pigeons, I came to permanent solution:
Lower barrel (fired first): modified
Upper barrel (fired second): full
This is usual sequence of firing in the field, although single selective trigger gives option to select..
The story does not end here, as boys will be boys and we like to play with toys (me first).
I often go for boar driven hunts, and in dense forest or bush on shorter range, for boar, shotgun slugs can be used.
Brenneke slug and similar are in my area generally known as "Brenneke" are designed with outer slant ribs in order to deform and pass through any choke.
But deforming on tight choke, (arguably) is not beneficial for external ballistic and accuracy, so although acceptable on my tests with modified and improved cylinder choke, I ordered additionally two cylinder chokes to try for better accuracy.
Finally with cylinder chokes, slug accuracy indeed improved.
As I shoot targets (rifle), I wanted to try shotgun slugs for even better accuracy, so from local back market i ordered iron metal sights (front and rear) which could be fitted on top rib: rear sight fits to rib air vents, and front sight to replace standard bead.
After installing the iron sights, when testing on target I could hit a coffee plate at 50 meters with both barrels.
So I was happy, of course.
But in real hunt this unnecessary, as with shotgun on running boar, I dont aim, I just point.
So later I removed these sights, and kept classic ways, with front bead only. Iron sights are now somewhere in a drawer in gun locker.
To conclude, for driven hunts, I use slugs with both barrels on cylinder chokes. For hunting birds using full and modified choke, while improved cylinder choke is resting in a drawer with iron sights.
