I received and mounted the Lyman sight and Sunday afternoon went to shoot it. Things didn't do all that good the first 2 sessions. Sunday afternoon was session 1 . I shot 460 gr bullshops and 70 gr 777 and 75 gr pyrodex. Took about 20 shots . First couple at 25 yads to see if it was on paper. It was so i went to 50 yards. took about a dozen shots and finally achieved about a 2 inch group. Not good. The main problem I encountered was the cap wouldn't fire on first pull. It took the first shot to seat the cap and then it fired on the second shot. I quit after about 20 shots of this and decided to try again later. Monday I polished the nipple to see if the cap would seat better.
I couldn't change nipples because the nipple is part of the breechplug. well I went back out and shot 10 more shots. same result, took 2 trigger pulls to fire. . I decided to take a little more off the nipple, so I used my diamond sharpener and worked on it til the cap was seated good but still tight enough to form a good seal.I was running low on conicals til an order comes in so I grabbed some 250 gr shockwaves with black sabots just for fun. I went back out and realized i only had containers of 100 gr 777 powder. decided to shoot it anyway to see if it would fire first time.
It fired flawlessly and i found that a 100 gr 777 and a 250 gr shockwave gives a great group. Not exactly a conventional load for a white I realize but a 3/4 inch group at 100 yards with open sights. I might have to hunt with that load. I will post some pictures.
The sight after installation
Sunday and Monday i shot off of sticks both days.Above is part of my loading and support crew.

On Tuesday i shot off the hood of the truck ,100 gr 777 250 shockwave and open sights at 100 yards.

The group is high I realize but a good group for me with open sights at that distance. I still have a long way to go to get the 460 bullshops grouping though.
