I don't have the Endeavor, I have the Triumph Bone Collector which I had to return to T/C because I couldn't get the gun to shoot to POA. When i got the gun back, it still would not shoot to POA. It appeared to me and my lovely wife that the barrel was not straight. I contacted the Repair Manager and told him of my problem. He told me to return it and he would personally get the problem resolved. Two days after they received my gun, Mr French called me and said they were sending me a new gun, that indeed the barrel was not straight. I received the gun and a box bullets, plus he has promised me a new spare breech plug. I put a new Nikon Monarch 2.5 x 10x 42 scope on it. With a lazer bore sighter, I only had to make 3 clicks left and it was bore sighted. With the old gun, I tried 3 different scopes and couldn't get it to shoot straight. Once this rain moves out, I'm going to shoot it. I have always heard T/C had good serice, and even though it took a little bit of communication, they have been very good. The final proof will be at the range. I love the balance and eay cleaning of this gun. I would think the Endeavor would be a very good gun also, but I didn't want to put the extra money into it. The regular Triumph to my knowledge has a wonderful reputation for realability. good luck!!!
