I am making the switch from rifle to bow hunting so I am still learning. My question is will your broadheads shoot the same as your field points or do you have to site in both differently? Thanks.

Mechanicals will fly like field points but you still need to tune your bow and site in with your broadheads.

so long as they are the same weight...

No they will not! Fixed heads require a more precise tune and better form to shoot well. They can shoot the same but 99% of the time they need to be tuned to shoot well.

You need to practice with them and determine how they fly out of your setup.

Yes that is if the bow and arrows are properly tuned!!! If there is difference and all factors are as close to ideal as can be it s/b minimal.
