has anyone used these tc sights
 

i picked these up on ebay i hope they match up

I used them years ago on a couple different T/Cs.
I had to do some file work on the rear sight for elevation, but they worked fine once adjusted. (drift front sight for windage - file rear sight for elevation)

thanks,I was wondering how to adjust thanks...ed...hopeing to use them at mountian man events i hear guys talking different powder charges for different distances lol i was just thinking of aiming higher

For target shooting I would find the load for best accuracy, then just adjust the "sight picture" for different distances. You can either gauge the depth of the front sight in the notch (eg - front level w/top of rear for most used distance, a little above the top for more distance, and a little below the top for less.), or use the same sight picture (sighted for maximum range) and hold lower up close.
I used to shoot a few matches (25 & 100 yard targets) and would sight for a "dead-on" hold at 100 then use a 6 o'clock hold for 25.
