If your talking about the Skinner Ghost ring, I here they are every bit as good as an XS ghost ring for half the price. I think you would have enough adjustment for elevation for a 30-30. If they are like XS sights, they have a long elevation adjustment shank on them. In my opinion, unless your going to use this sight say for 100 yds or less, it would work fine. I think the williams would be more accurate because it's along the lines of a peep sight with a smaller apature. I have an XS ghost / scout setup on my 1895, but I use it for dangerous game and a quick shot if needed. I have a Williams peep on my .35 and it gives me great groups at 100 yds. I use a tang sight on my buffalo 45-70. I shoots great with is sight, but takes a lot of practice to get use to it at different ranges.
