Right before the hunting season begins, a trend seems to show up in threads for crossbow reviews where people complain about their broadheads not grouping or flying well after being shot. While a lot of people automatically assume that the problem lies with their broadheads, this isn’t actually the case.
Generally speaking, broadheads are finicky. No matter how perfectly tuned your crossbow may be, your broadheads may still fail to hit your practice points in the end because of your arrows or your crossbow. You just need to figure out what the actual problem is in order to shoot your broadheads from your crossbow more accurately.
Before anything else, you should take a look at your arrows. As mentioned earlier, arrows that group well with installed field points do not necessarily equate to broadheads flying well from a crossbow. In fact, they won’t a lot of the time. This doesn’t mean that the broadheads are to blame, though. They are merely responsible for magnifying all of the problems areas that you already had with your crossbow and arrows in the first place.
Common Arrow Issues
There are three very common issues of crossbow arrows. The first one lies in the change of balance at the front, which happens when the arrow’s length changes as you screw a broadhead on in place of a field point. Since broadheads weigh the same as field points, a lot of hunters think that this won’t change anything. However, since broadheads are longer, there will actually be a slight change.
Screwing on a broadhead affects where the arrow flexes a little. It also affects how it comes off of the crossbow’s rail. Because of this, most broadheads that fly out of crossbows well have short ferrels. If this is the only problem, then every arrow that is tipped with a certain broadhead should group together and you should be able to adjust your scope in order for things to work.
If things still don’t work out after that, then the problem might lie in the arrow spine. Generally speaking, the arrow spine should be consistent between arrows. The only time this isn’t applicable is when it comes to carbon crossbow arrows. Since the shafts of carbon crossbow arrows are manufactured differently, their spines can differ when measured anywhere around their circumference.
