Sighting in broadheads

[mrklean]

Quick question i have a Bear truth 2 and a PSE xforce, when i sighted my truth 2 from field points to broadheads like 6 inches high and 3 inches to the left so i had to do some adjusting, when i checked my Xforce last night at 30 yards from field points to broad heads i would say i was about 2 inches to the left at the most so really no change at all. Im using the same arrows and broadheads for both, my question is why such a difference between the two? I was wondering because the PSE is more of a speed bow if that was causing less change but wasnt sure. Any ideas

Two things:

1. Form/bow torque;

2. Tuning.

The first, you may have a tuned bow on one or both of your bows and you could still get changes in point of impact with broadheads if you are torqueing the bow. Some grips cause people to torque more than others. Its amazing how much shooting form can alter arrow flight - this is especially true when shooting broadheads.

The second, and most likely, is that your bow (or bows) are not tuned properly. Most "bow guys" believe that if your bow is properly tuned you can get broadheads and field points of the same size to group together. There is alot of fine tuning that can be done to a bow to acheive this state with your equipment (many of which are beyond my capability.) It doesn't sound like some of these things have been done on your bow.

Finally, and the most obvious factor (still a tuning issue), is that you are shooting two entirely different bows. Both bows need to be tuned and need to be properly set up - which includes a proper arrow spine and total weight. Not all bows can shoot the same arrow and broadhead combo the same.

Yep, what he said! The reason both bows don't shoot the same for field points as they do for broadheads is because each bow is not tuned properly. Do a search on how to microadjust your rest and you'll be in better shape.

Also, two inches left at 30 yards would bug the heck outta me! I would definitely tune it so both broadheads and field points were hitting the EXACT same at any distance I'd ever consider shooting at an animal.

makes sense my xforce was tuned the other week at the bow shop, my truth 2 has never been tuned. I think i will bring it in to the shop during the off season and get it tuned up and see how it shoots.

This topic has been done to death but I'll still give you my opinion.

You only have to look at a field point and broadhead side by side to see that they are (probably) not going to fly the same. Yes, you could adjust the rest untill both HIT the same place. That doesn't mean they both fly the same. Personally, I spend all summer fine tuning my bow till the arrows fly the best they can. Now you want me to change that set-up simply to make my broadheads hit the same place? No way! IF the broadheads fly straight and true, simply adjust your sight and move on.

Why are both bows treating the same heads differently? It may be tuning issues, but each set-up will push arrows out differently.

[mrklean]

Thanks don thats what i did with the truth was just adjust my sight. If at 30 yards i can keep both broadheads and field points inside of a pie plate (4-6") i feel confident enough to drop a deer at that range

[Stratosman]

Fine tune the rest so both are hitting the same spot, fine tuning will affect broadhead flight more so then field pont flight, once you get them hitting the same spot, then you adjust your sight to where it needs to be... do a search on this and it's actually quite easy and doesn't really take long at all.

Not saying this just to be a contrarian - I am just trying to understand the logic, but how can two arrows with different tips (assuming the total weight of the arrow is the same) both "fly straight and true" and not be hitting the same place (which is what I think your post is implying)? I could see one hitting higher than another, but on the same left/right line due to weight difference. But, if two arrows of the same weight aren't hitting the same place left to right, isn't atleast one arrow not flying true? At the same time, if arrows are impacting the same spot at each different range, isn't it almost guaranteed that they are flying the same?

I agree that some broadheads, due to dynamics, just might not be capable of hitting the same location of a field tip, but most broadheads and bows can be tuned so that both broadheads and field tips will fly the same and consequently impact the target in the same spot.

Shoot expandables...

[mrklean]

no thanks

Expandables aren't necessarily the answer either- despite what you hear, they don't always hit the same spot as field points. I think Don's a smart dude and knows a lot about archery, but I really don't agree with him. Tuning a bow isn't rocket science- it just takes a little know how and some time. Tune your bow(s), then tweak them to make the same point of contact with your field points and broadheads. It's not too tough.

Why you wouldln't want to be hitting EXACTLY where you're aiming at 20 or 30 (or 80) yards is totally beyond me. If you think being within a pie plate is good enough, that's cool. But the dead center of your pie plate sized groups should definitely be the middle of the bull. I can't understand the logic behind this not being the case, other than "good enough". "Good enough" will result in poor shots and unrecovered deer.

Nothing wrong with a good expandable, IMO. However, not all expandables are good...

Good luck with all this- it's tough sorting through all of the opinions and takes on this stuff when you haven't done it for a long time and don't have a "guru" to rely on. Of course everyone on the internet is an expert...

I happen to agree with Don on this one. Just because a bow/rest/arrow combination can be tuned to make broadheads and field points of the same weight impact the same spot, that's not the right thing to do. And especially if you haven't verified that after doing such tuning, you still have the absolute best flight of your broadhead arrow possible. Somebody show me where it says that when you put a broadheadhead on the front of your arrow that is longer than a field point, and creates a different balance point for the arrow than a field point, and that can act like wings in catching air vs. a field point, that is should impact the same spot as a field point, regardless of whether it is "tuned" or not? Get the broadhead arrow flying well, and grouping well, and move your pins for the ultimate accuracy.
