I think you may be off buddy. I tried to do a setup with the FMJs for myself but the best I could get was like 19-20% FOC and that was with 320 grains up front. 220grn Muzzy Phantom and 100grn bass insert
I'm sure Germ's FOC is lower than 27% I have 27.5" FMJ 400's with 100 grain brass inserts and 125 grain Slick Tricks with feathers on the back end and mine came out just over 21%

I figured mine the Old fashioned way! By measuring;)

Sounds sweet Greg.

I'm thinking about going with a 100 grain brass insert AND and 125 grain broadhead on a 28" Terminator Lite Select shaft.

That would be around 500 grains and 21% FOC. I'd get around 260 fps.

So many choices! :D

I thought I was off too, LOL Why I ask in a thread[8D]

At first I came up with what you did, but than my brain got in my way and I thought you put in 200 instead of 100.


Now how do you expect to be president Germ if you keep getting nominated "FORUM MORON OF THE MONTH"? LOL!!!

Hey even with that 15% FOC that 525grn arrow should still hit nice and hard.

Yeah, I really started contemplating it after shooting a 3d shoot with Jeff and Chris Propst (from Drury Bros. fame...) this summer. Jeff was shooting the arrows he'd made up for his last elk trip that day, and he was out-penetrating me by a good two to three inches in each target. Really started me thinking about momentum and all...

I remember Germ and I was confused if you remember.:D

I had never used that formula and showed you the one I use.I doubted the 200 at the time but since I had never actually used that formula,I wasn't going to doubt it.I quess I should have tried it on mine.[8D]

Sorry for leaving you hangin like that.:D

I just built and have been pounding my glendell buck with a29 inch 340 (11.1 grains per inch)Axis FMJs, blazer vains... 100 grain muzzybrass inserts up front with 125 grain practice tips. I'll be shooting 125 grain Eclipse teflon coated4 blades come August. My Btech Libertyis set at 80lbsmaxed.. I've never had an arrow fly better orpenetrate like this set up.. I am very pleased to say the least ..extremely clean arrow flight from the Trophy Taker..

Hey shed Im shure that is a nice hard hitting setup. But I ran your numbers too and it comes up to be about 16.32% FOC. Extreme FOC like Dr. Ashby is talking about is anything 19% and above. Those FMJs are nice and heavy but I know I ran my numbers with them time and time again and it is real touogh to get an Extreme FOC arrow with that shaft.

But still im sure that arrow will hit nice and hard.:D

I agree that high FOC arrows are certainly very stable in flight, my current set up yields 12% FOC. They fly extremely clean.

I'm just thinking outloud here, but how much of this is overkill? What I mean is, I'm shooting a 480 grain arrow, 12% FOC, I'm getting 84 #'s of KE, and while I'll admit I don't know a whole lot about momentum, I'm thinking I have quite a bit. If we're talking about whitetails, all we're really doing now is determining how far in the ground the arrow will be after blowing through said deer. Moose, cape buffalo....Ok, maybe that's not enough, I just don't know.

I'm not arguing here, just thinking. Someone tell me what I'm going to gain by adding another 9% FOC. My arrows are flying like fickin laser beams attached to my frickin bow.....And they hit like a tank. They fly extremely clean, they're almost fun to watch in the air.

Don this may seem like a cop out but just read the Dr. Ashby article that was posted in the first post. I believe it will answer your questions much better than I can put it into words.

Are Extreme FOC (19% and up) overkill on whitetails? Yeah probably but IMHO I would rather have overkill in this situation than underkill.

Read the article, I believe you will find it an interesting read.

Chad,

It's been quite a while since I've perused the good doctor's article; wasn't most of his research directed at African game?

Not saying it doesn't help to maximize effectiveness in any situation...
