Shorter shank 100gr field tips?

[Randonee]

I’m looking for 100 grain field tips that have a shorter non-threaded shank. Please see the photo for what I’m referring to.

I need a shank that’s about 0.31” or less. All of the 100 grains points I’ve been able to try are more like 0.34”. The story is that I installed the HIT inserts to work with 125 grain points, which (surprise to me) all seem to have a shorter non-threaded shank.

You might be able to get something like a tophat collar to put over the end of the shafts, will grow that area a little. They add like 3grs. I have some Day6 points, I'll try to measure them. They tend to have a little shorter smooth shank on them.
