ok, i'm at full length. what increments? 1/4 or 1/2 inch? i'd like to shoot a 150-160 gr broadhead rather than 125, BUT 125s such as muzzy are available in local stores. i do favor traditional broadheads ...

oh, yeah, i use a tab, 3-finger under nock release.
(OP: i apologize for usurping your thread)

If you're getting the full 45lbs out of that Bear bow ,assuming you're using a B50 [Dacron] string, 1916 aluminum or 600 carbons should work.
With the 600 carbons start with a full length shaft. I'm fairly new to carbons but I'm shooting the 600s on my 45lb Bear Grizzly with a BCYX string,29 inch arrow, with a total of 175 grains up front.
I have a 50 grain insert with a 125 grain head.
You can use a standard insert and add weight if you need it, 25,50 grain weights are available.

thanks, tg. i draw about 30 inches. it's a dacron string. i'd like to keep using the 400 carbons because of expense of replacement.

I like 3 fingers under too. I look down the arrow.

Ok,3 inch draw, you gettin 50 to 51 lbs
Probly have to add weight to the 400s

thanks, tg ...

Lol..I meant 30 inch draw not 3 inch.
I'm not very good at typing on my phone.

figured ...
