No, if its that hard to get the insert in go to a thinner plastic, maybe saran wrap. I have found that with 100 grain brass inserts I’m usually tearing the plastic off after they are half way down or it ends up to tight. 50’s are ok the shim the entire thing. You have to experiment a little because not all inside arrow diameters are the same. Goldtips for instance seem a little bigger than most.
Joe, I’ve never tried that type of target but it sounds like your right, cut the nock end on that one.
