The 108 scenar is the same geometry as the 123 I think. I used the 108s in my 700 bolt action for silhouette. The gunsmith I am sure used a SAAMI reamer, but I am not mag length limited. Here is a load that I've used, and I have some crunching. This may have been on new brass without any vibratory settling, etc.
I agree though that with too much compression, the COAL/CBTO whichever you will use may not be that consistent since you may end up pushing the bullet back out as A5B said.
