Thanks, Chuck. I may just go ahead and open them both to .020" and not look back. I've been competing with that constriction in both barrels of my MX-8 in the main events for the last couple of years and shooting the best I ever have since beginning. Only problem is, I do a lot of woodie shooting in beaver ponds here, and .020" is a lot of choke on those close birds, and man!, they can be close!
Another alternative would be to have Briley thread the barrels for their S-1's, as I mentioned earlier, and leave the trigger alone. That way I could put in open tubes for the woodies, and .020's or .015's for clays and big ducks at longer range. Long as I use the same constrictions in both barrels it wouldn't matter anyway.
Thanks, Stan
