I have a Thompson Center Pro Hunter

I have the Leupold scope base and rings on the black powder barrel, the bottom of the scope base makes contact with the barrel the complete length of the base.

Today I purchased the rem 7mm mag barrel for it and the Leupold scope base DOES NOT have full contact the compete length of the base to the barrel. About 1/3 of the base towards the muzzle is not making flush contact with the barrel,, the reason is the barrel is taper downward.

This is a one piece base and has 4 screws attaching it to the barrel in the back half of the base.

I'm wondering if this is the correct base, Leupold #54798, and if it is going to work.

Thanks!!!

I just mounted my 270 barrel with a weaver style one piece base and have the same situation. Gun sighted in ok and point of impact hasn't changed in over 25 rounds.If it bothers you get the tc 2 piece bases and swap her out . I see no problems in mine as of yet.

I own an H&R .308 that has the same downward taper as your barrel, I also have a gap towards the front of the base, but it's ground checked plenty of deer so, I'd say it's not causing any problems. I am like you though it does bother me!

sorry fubared in wrong spot
