I purchased a used Browning BSS 20 gauge side by side shotgun last August. Using it for doves on opening weekend in September it immediately fired both barrels with 1 trigger pull. It has the barrel selector and I had it set for the right barrel. I contacted the seller and he agreed to pick it up and take it to his gunsmith. A little over a month later I got the gun back. Immediately doubled with 1 trigger pull. The seller took it back to his gunsmith again. Another month later the gun came back. I shot it in front of the seller this time and on the 2nd set of shells it doubled again. He took it back to the gunsmith for a 3rd time. Just got it back yesterday. On the 2nd set of shells it doubled AGAIN. Hey, at least that gunsmith is consistent. He's failed to fix the problem after having the gun 3 times. And yes, I do have the gun firmly against my shoulder. I selected the left barrel to fire first and it also doubled. Both barrels don't fire at the exact same instant. There is a fraction of a delay between the two barrels firing, but it's only an extremely small delay.
Here's the thing that is puzzling to this 73 year old disabled Vietnam veteran's brain. It does this only with light target loads, 7/8 ounce, 2 1/4 dram equivalent shells at 1200 fps. If I shoot field loads with a 2 1/2 dram equivalent load, 7/8 ounce, at 1210 fps, the gun does not double. I fired 75 rounds of the 2 1/2 dram equivalent Federal Top Gun 7/8 ounce shells at 1210 fps with no problems. I put in 2 shells of the Federal Target 2 1/4 dram equivalent 7/8 ounce loads and the gun doubled. Then loaded some more of the 2 1/2 dram equivalent loads and no doubling. First I thought that the heavier loads would produce enough recoil to jar the second hammer/sear loose, causing it to double. But there must be something else like the inertial block system spring is too strong and isn't working properly with the lighter loads.
I did test the gun with light and heavy loads while I held the gun out to my side, the buttpad just in the air. And the gun doubled no matter what kind of loads I shot or which barrel I had selected. Now, I don't dove hunt shooting from the hip. But I would like the gun to work with either target or field loads.
I have some Browning Citori Lightning shotguns. I've tried shooting light loads in those guns and haven't had any problems. So don't know what the difference is in the BSS that it doubles with light loads. Anyone have enough experience with the BSS shotgun that they can shed some light on my situation?
Thanks,
