Now that Jim Reynolds is kinda closing up shop and is harder to reach I figured I'd ask here. I have my 58" thunderstick mag brace set at 6 3/4.  Bow is 50@27 and I'm probably drawing a tad less than that...maybe 26 3/4. It seems to shoot good at this brace with 29" gold tip trad .500s with 225 up front.  I am just wondering if there is an "optimal" brace height for this bow. It seems louder around 7 1/4 which I assumed would be on the high end of the spectrum.

Maybe I should quit worrying but I've been bare shafting like a lunatic and just trying to make it perfect!

Mine shoots well at 7-1/2".  I'm shooting about 53#s @ 26".

That's with a 8 strand SBD string.

I had one and it was 7"

I keep mine at around 7".

My Mag's a 58", 45@28", and I draw right around there. Mine seems to like 7 & 3/8", give or take a twist or two. Shooting wood arrows, 45/50 or 50/55's, total weight around 1o.5 to 11 GPP.

I emailed Jim a while back when I got the bow, as I recall he said start around 7", and just go from there.

FWIW, I have also been finding type and placement of silencers to really affect how quiet the bow is.

Where did your silencers end up? Mine are about 10"s from
The tips

I've set them 18'" on center from top limb tip, 17 1/2" oc from limb tip to center, bottom limb. for 8 strand D-97, wool silencers. VERY quiet right now, 3 fingers split.

Ive got several Of Jims bows,depending on the arrow Im shooting they seem to like anywhere from 6-3/8 on up to 7-1/4". Mine are all 60 and 62". My son has a 56" mag, and its right in that same ballpark. I find if I get too low with the brace, I either start catching my wrist with the string, or I get a little bit of vibration. JIms bows are shock-free when tuned, so I just start at 6.5" and bump up 2 twists at a time. You'll know when you find that sweet spot, dead in the hand and very quiet.
