EFOC w/ Gold tips, how?

foudarme, could I trouble you for your draw length and how much your cutting off your 340 GTs. Nobody is saying if they are cutting the 7595 down any. I'm about to go to 300s.

:eek:  I don' t know, guys how you can shot properly so weakly spined shafts from your bows. I get a clean relise, shoot dozen of arrows every day for 20 year but out of my bows in the range of 60-68# 29" I need a good GT 75/95 al insert 145 BH and weight tubes,I can't add much more weight on front

feliciano,

Nobody ever talks about how much center cut is on their individual bows. Some are IBO legal at 1/8" shy of center...and my Morrison is cut 3/16 PAST center.

Shooting only 48# and drawing 28 3/4", shooting 29.5" GT5575, I use a 100 gr. brass insert (used to use the GT weights with all-thread, but hated all that fussin around) and a 160 gr. head.

I have about 24% FOC. Learned recently that the cut to center or past riser equates to the arrow having trouble deciding which way to go into paradox...and can lead to some foibles in flight if the release isn't perfect.

I'll be working on shiming out the sideplate back toward center or SHY of center some to get my Foc up to EFOC (28%). I expect two things. One, I will make the arrow release a bit more forgiving, and two it will enable me to use smaller, quieter feathers than now.

Stealth is the game...so why not with my arrows having smaller quieter fletching on them?

The amount of center shot of a riser makes a huge diff in spine compared to draw weight!  Most folks have to prove it to themselves. I did!

Doc nock, I brought that up the other day in a discussion on how much to cant the bow. The center cut and the total center shot affect the cant of the bow as well.
I have a 56# 58" Morrison Dakota and I'm shooting 31" 340 GTs with only 145 grains up front (using 5 grain weight tubes)and their flying like darts but start tweakin with heavier than 145 grain tips. I may have to go to 300 spine arrows of some sort to get at least 200 up front. The brass inserts I got didn't fit right in a gold tip (.242-6), one size for all doesn't work.
I have some 100+ GTs with 200 grain tips full length and they are a little too stiff. They have 8 grain weight tubes.
Oh ya, if you tune just right you don't need feathers at all Doc.
