I'm shooting a tomkat 70#, 27" DL, Goldtips XT's 5575 and have been shooting 3 blade 100gr muzzies but I was wondering if it would be a good or bad idea to try 125gr instead. I know it would change my sights and I know the impact difference between 100 & 125 grain, but I was wondering if it would change the accuracy? I hunt whitetails and hogs. What do you guys think, would it make a difference with accuracy or not. Thanks for the input.

Only way to find out is to try.

I can pretty much shoot 100 and 125 grain heads interchangeably with very little differance in points of impact to 50 yards.

There is a bit of a change in pins setting with the 125 gr. Your kinetic enerngy will increase. Another change with a heavier tip is arrow spine. The heavier tip will weaken the arrow. Check the Easton chart to see what arrow they recommend. The chart recommends heavier arrows than what is needed. When you find your cam, weight and draw length. Go one to the left for optimum arrow performance. It works and you will be very satisfied with the results. I shoot 125 gr. Thunderheads and they really make a difference on impact.

Keep in mind if you change heads weights you will need to retune your bow. Only after doing so will you be able to tell if they are an improvement or not.

Thanks for ya'lls opinions. Yes I know I'll have to retune it if I change, but sniper, what does that mean that a heavier tip will "weaken your arrow"?

What he is saying is when a heavier tip is added to the front of an arrow the arrow
will actually bend/paradox more as the arrow is being thrusted foreward thus
weakening the spine some. This is not always a bad thing though. I have found
on my GT 55/75's I shoot tighter groups with 125 gr. tips compaired to 100 gr.
tips. Many target archers use 300gr. tips, or heavier, to weaken the spine of their
stiff line cutter shafts to gain accuracy shooting indoors. As stated above the only
way to see if it helps you is to do it. You might want to try 125 gr. fieldpoints first
to see if it helps your grouping before sinking money into new broadheads. JMHO.
Let us know how it turns out.

dsheally hit the mark. A heavier tip creates more resistance on the arrow. This will cause the arrow to flex a bit more then the 100 gr. tip. Many bows will actually shoot more consistent and tighter groups with this added weight. In a hunting situation, more weight is more kinetic energy. I have found that my bows will tune much easier with a heavier tip.Quite often the bow will be much quieter and will have much less recoil and vibration. If you shoot 3-D targets, less weight is preferred to increase arrow speed, just in case you misjudge a long shot. I think you will enjoy the difference. Oh! P.S. You think your 100 gr. did a job on your trolling motor battery, take a crack at it with a 125

Thank you Sniper. The good thing about having this and other sites is to help each other
out when needed.
