Tip wieght change..opinions please

[Sam22]

I shoot a PSE nova, with the older, but nice F4 cams. I pull 70-73 lbs, shoot carbon arrows (Whitetail hunters maybe) mechanical release. I want to drop from a 125 grain tip to either an 85 or a 100, to try to reduce arrow drop downrange. What do you guys think? Will it help significantly? Penetration still adequate?

i shoot 70lbs, and shoot a 100gr. tip. I don't know your arrow length, mine is a 28" arrow and i don't have any problems

While every little bit helps....you're not goin to flatten you arrow by shaving 25 grains.

Keep in mind adjusting tip weight adjusts arrow spine as well.

Changing tip weight changes your Front of Center. That can really affect broadhead accuracy. Keep it within that 8-12% range. Closer to 12% for broadheads is ideal. Measure your arrow for total length without a broadhead and then put a mark at the halfway point.. then screw in the broadhead, and balance the arrow on your finger. mark that point of balance. measure the distance between that point and the point which is half of your arrow length. Divide that difference by the total arrow length and you have your FOC%. Hope this helps. Any of the more knowledgable tech guys in here that read this, double check that range for me. I have always been just under 12% and have gotten my best results around there. I am not sure what exactly the acceptable ranges are. Any corrections would be appreciated and informative.:idea:

Not to mention, FOC. Could cause more problems than it is worth. How fast are you shootting? At 70+ # and carbons, you should be moving right along, as it is.

I shoot a Mathews Legacy at 70# with a 28" Gold Tip XT 5575, 3 four in. feathers and 100 gr. tip, I get about 266 fps. With this set up It shoots through paper real true. I wouldn't shoot 125 gr. tips unless I was hunting bigger game, like Bear, Elk, etc. I think the extra weight makes a big differance in arrow drop over 20 yds. Deer are thin skined and unless you hit a large bone you shouldn't have any problem with a good pass through.

Hook Daddy,
Thanks.
I came up with a F.O.C. = 11.6% using 125 broadhead, 31" Carbon Express 300. Sounds good to me, I was thinking of going to 100g. but I think I'll keep what I have. I was using Alum. 2315 last year and at 62lbs I was getting 212fps.. The alum. was total of 534g., that is why I went to carbon but I don't know my fps or total weight yet.

And I forgot to mention that the 11.6% was with a homemade lighted nock in it too.

How far is "downrange"? I hope you're not another one of those guys taking pot shots at deer at 50 + yards. Please say it ain't so?

Howdy Sam: I agree with HDS that FOC is the main concern with your proposed change. As a matter of fact, FOC can be one of the most important things to consider when you're choosing a broadhead weight.

Someone correct me if I'm wrong, but the total length of the arrow and the halfway point should be determined by measuring the arrow with the broadhead attached - this makes sense to me anyway because that's how you're going to be shooting it.

Do a search on this forum for Front Of Center or FOC; there also are some other internet sites that give good advice on this - try a Yahoo or Google search too. Good Luck!

You may want to change arrows too if you are changing your tip weight. Like mentioned above you want to watch the FOC, with a change in total arrow weight it would be easier to get the FOC correct with lighter heads.

Changing your head weight will not significantly reduce your "arch" in your arrow flight, but reducing total arrow weight will.

Droping 15grs of my set up only equals 3fps faster through the chrono, but yeilds the same KE as the drop is not that much and the 3 fps makes up for the weight lost in the equation, BUT my arrows do not fly as good as with the heavier heads (100grn heads 371 total vs 85grn heads 356total)

Hope this helps

Thanks fellas, I will calc my FOC and decide from there. For what it's worth, I wouldn't shoot at a deer outside of 30/35 ( I practice alot ), but I shoot some 3-D and plan to shoot more this summer, just for fun, I want to start shooting in the 40-45 range. I shoot 31 inch arrows, it just seemed to me that I get alot more drop than the guys i shoot with, they have faster bows, and shoot light tips....

I think it's a blast shooting long range. If you can find a place to do it, shooting 60,70,plus yards is alot of fun. I spend a week shooting long range in september just before switching over to my broadhead setup. Makes those 20 yarders seem like nothing. Confidence is my best weapon in the woods. Good luck!
