Dinny: I put a slug gun together before the deer season from a 20 gauge Tracker ll barrel which I picked up on the classifieds, and from what I have read here, it is basically the same as the ULSH barrel but maybe with the old style rifling being the only difference. I mounted it on my frame with a Boyds thumbhole stock, and added some lead to the back of the buttstock, mounted my scope, and a sling, and I estimate the gun weighs in at a little over eight pounds.
I've shot 3" Remington Buckhammers that grouped cloverleafs at 50 yards, and took two deer already, one at 40 yards, and the other at 65.
I've now switched over to Hornady SST's that shoot a 1 1/2" group at 100 yards because I've seen a big buck now a couple times at about that range, and feel confident I can make the shot.
I really like this slug gun, and how it carries, as it is also a pleasure to shoot, and I compare the recoil to being between that of my .357 Maximum, and my .243 Ultra.
If the recoil is too harsh a little weight added to the stock will tame it really well, and you will like how it carries, as it won't weigh a ton like an USH would at the end of the day.
