I'm not doubting that another kind of tripod may be better for your needs especially if you are hunting hill country or super long range. With that said, I have three BOGS and none of them are flimsy. They are solid. I've only ever had two mishaps with the BOG. 1. I loosened it up and forgot and my rifle fell out of it. 2. I "squeezed" in the legs to make it taller instead of extending them, walked away and when I came back it bumped it with my foot and it tipped over. Both were 100% my fault and no fault to the tripod whatsoever.
Again. I am not trying to debate. Just curious, how is yours flimsy?
When I put the rifles in the "clamp" I slide them fwd as far as I can to help with balance and to keep the pressure from clamping down on the barrels on my bolt rifles. I hardly even tighten them that much. I keep them loose enough that if I have to swing right or left and the crosshairs aren't level I can just twist the rifle a tad and be good.
