Which tap for scope?

I have finally stripped the front hole on the front scope base hole of my .307 M94BB. The hole is shallow,even though it goes straight down to the threads of the barrel.This causes the scope base screws to be too long, and I stripped the threads before grinding the screw short enough to fit. I would like to re-tap,but I'm not sure which size to use.I know I'll need a bottoming tap,but should I go up a size or stick with the original size. Not sure how strong it will be if I stay with the original size,as the threads look pretty bad.Suggestions?

I would suggest you try the original size first, most likely 6-48, can be had fron Brownells, but if you order, go ahead and get the drill and tap for 8-40, which is what Marlin uses.

If that don't work I'd sell the rifle, and since it needs work I'd goa against me better judgement and give you $100 for it.

Aren't you a pal

Thanks for the advice anyway,I'll see about getting those taps. I really,really hope I can fix it, I'd hate to have to sell it but I new I could count on a fellow levergunner to take it off my hands!

Hey I'm here to help.

Besides it would look nice next to my 375 BB.

before going up one whole tap size, as they said try brownells they sell a o/s tap in the same size with screws and it is a couple of thousands larger
the bare eye can barely see the difference.

or just move up to the larger size.
