Point weight for foc carbon setup

[DVSHUNTER]

I have a 45@26 aggressive r/d longbow that I'm trying to spine some 33/55 gtold tip arrows for.  They are cut to 27.5 and I draw 26in.  They have a 100gr. brass adapter installed and I want to keep that in.  One problem is I'm not sure of the cut out of the riser as far as from center.  I dealy I would like to shoot a 190 grizzly with whatever adapter I need.  I would prefer a steel adapter.  I'd like as much weight as I can get and can still cut the arrows down another inch.  What do you think will work?

David- I think the best thing you can do when trying different arrows i.e. FOC, Efoc ect. it to experiment.  None of the charts and short cuts have worked for me.  They might get you in the ball park but taking the time to figure out what works with your shooting style and bow is the best was to go... atleast thats been the case for me.

Stu's calc says that's perfect at 1/16" cut, if not cut that close it will make them weaker - enjoy them

My advice would be to get your hands on various weight adapters and try them out, including aluminum, simply to vary your options for getting the right good-flight combo.

I tried to do some extrapolating from some 55/75's I had tuned for a 45 lb bow but I don't know if I can even get close due to differences in draw length.I was thinking?,a total of 200 grs upfront.This could be way off.

I would bare shaft what you have and see what grain point it likes now,but start very low in point weight,like 100 or less.You already have 100 grs of insert.Cutting one inch may give you 25 grs more point weight.

You may have to go with a 160 Grizzly,aluminum adapter and aluminum insert,to get the right weight.The other option would be to move up to 55/75's but that will make you a considerably heavier arrow,given added shaft weight and front end weight.

You may already have 190 grizzlies but they don't make that weight any more.They are advertized as 200 but usually come a little heavier.

You will just have to bareshaft and see but I'm not sure you can get away with that much weight on the front of 35/55's.Every setup is different though.

Thanks for the info.

Jim thanks for the extra effort.  Thats the kind of help/assurance I was looking for.  I'm not opposed to getting different weight heads, Its just I've got a dozen good 190's and like the head.
