Titewad is a very compact powder, and it is difficult to get a good case fill. I used the exact same load as you, but on a Hornady loader that has a lot more adjustments to be made. I was able to get them to crimp "decent," but just barely by tweaking every adjustment possible. You will want near zero pressure while seating the wad, crimp start as long as possible, and with the load all, the best you can get on the final crimp is doing it by 'feel' until it's right. This might get you there. An overshot card most definately will. Your load is on the mild side, and an overshot may safely be added. Once your TG is used up, you'll be much happier with a bulkier powder such as Red Dot, Green Dot, WST, or American Select. Availability is improving. Another option would be the WAA12SL wad which is designed for 1 oz of shot and takes up more space in the hull. You'll need a little wad pressure with these. Off book here, but I've found that to be a safe substitution. I've found the Rem Gun Club hulls to have some variability in capacity and crimp location (as with most bargain priced hulls). In particular, I've found them often to have a "short" crimping section. By gentle and deliberate pressure you can lengthen this in your crimp start station, which makes the crimp better if your powder/wad/shot column is short as in your case. If you get too rammy, you'll buckle the side walls.
As for the WAA12 wads, there is a slight difference between the older wads for the compression formed hulls and the newer wads for the HS AA hulls. It is supposedly irrelevant for reloading.
The way things are in the world, I would strongly encourage you to phase out 1 1/8oz loads and work towards 1 oz unless you have a specific need for the heavier charge. I made the switch several years ago when shot topped $40 a bag, and never looked back. My scores don't know the difference, even at the 23 yard line or farther.
