Does brand A shoot well? Is it better than brand B?
I've tried a lot of broadheads over the years. Brand A was really good, but brand B seemed to do good, too. I did have a problem with brand C - they weren't accurate from my setup, so I never hunted with them.
Well, this year I tried brand D! They beat everything I've tried in the past! Flat out great performance. Two shots, two deer down and out very quickly!
Then it hit me - it wasn't the brand of broadhead I was using - it was the fact they shoot very accurately with my setup, they are scary sharp, and I put them right where they should go!
The only way to find brand D is to buy a pack and try them in your crossbow. If they are sharp and they shoot accurately it's up to you from there. Put them where they need to go and you will have plenty of meat.
Not trying to be a smart a&&, but the brand and type have little to do with the effectiveness. If it's legal size (cutting width), super sharp, and you put it in the right place (for me that's through BOTH lungs), it will do the job.
I've also noticed different results for different people here when it comes to accuracy. I figured out quite a while back that it is the complete package that gives the accuracy results. By that I mean just because brand D is very accurate from MY bow with MY arrows doesn't mean you will get the same results. I may have a different weight head, a different arrow shaft, of different fletching and get completely different results. Any change in any component CAN make a huge change in results. The only way to know is try them in YOUR bow with YOUR arrows. Picking a brand a lot of people have had good results with will narrow down the search, but you still need to test carefully for accuracy.
