Frank, Nice to see that I'm not alone in craving a Dom GB caliber Dahlgren, it'll make a perfect compliment to my GB Dictator. I'm trying to limit the number of calibers that I have to keep ammo for. Plans are to mount on a front pintle barbette carriage a la Zulu, should be an interesting build if the occasion ever arises. Dom knows there is interest out here but for now anyway his focus is on smaller barrels. Best Regards, LS
