Accuracy Back In The Window

It has been a couple of weeks since i wrote of my sudden woes with inconsistant bolt placement with my new Exomax--I had bought the Flemish ff after getting somewhat used to shooting the factory string-

after about a week of not shooting- all of a sudden the groups opened way up--up down left right--real inconsistant---I had installed the sts silencers for it so I took them off--same thing--put the factory string back on--somewhat better--I had tried every combination of string arrow that i could come up with---I had 2 identical sets of arrows and even numbered them---I was about to give up--Then i remembered the last thing i had done was to wrap a hi-density self-sticking foam insulation around the outside pieces on the foot-stirrup---So i took it off and went and shoot a 1-1.5 in. group at 30 yds.Today after just shooting with the factory string and sts reinstalled--the accuracy is back-----

I had noticed some seemingly minor serving seperation on the Flemsih string--i at first thought the other string to be the culprit---now im wondering if the stirrup wrapping was the problem the whole time---anyone had any similar experience?

sipsey, I don't see how that could cause any problems with arrow flight. Has to be something else for sure.

If it is the foam insulation ,then the arrow was probably hitting with the fletching or something causing the arrow to deflect slightly .
Thats my read .

i agree that is the only way i could possibily see the foam causing the problem

Shot for a while this afternoon--put the flemish FF back on--made minor sight adj.---shoots just fine---I am really at a loss to fully explain why it started grouping poorly--then back to good---I am shooting off of Stoney Point shooting stix---these rounds of shooting i have strived to place grip and shoot with as much consisitancy as possible off the stix---other than that i have no clue as to what went wrong--then went right

I'd have to agree with Doe Master, probably the fletching hitting the foam.

Wabi--I understand your leaning towards an obvious cause--But i can assure you--the insulation was tightly wrapped and was quite outside the bolt window--The one thing i have done this round is to increase the brace height--Before i had the string --very lightly--touching the sts surfaces--now i have then between 1/16 and 1/8 " above the pads---also i think i may have been inconsistant in proping the forearm on the stix---as i said---i could see nothing "Obvious"---maybe it was just a combiation of factors---very puzzling though--

See if this scenario has any merit---In traditional compounds a stabilizer plays a vital role in dampening the bows vibration to avoid the bow sight picture from prematurely jumping before the arrow leaves the rest---On the crossbow it seems the stirrup is positioned and indeed acts very similar to a traditional stabilizer---I noticed the bow seemed to jump harder with the foam on it--maybe I unbalanced the harmonics enough to transfer more "jump" into the rail, etc--With the insulation off and a new approach to prop and grip--there seems much less movement-jump at trigger pull---what do you think?

Thats a really good setup bstout --I did bring out my sandbags for bench shooting the rifles at one point-

I just came in from shooting 20-30-40-50- yds.---The bow is performing as it did right out of the box--excellent!--I now have no problems keeping the groups in a 4 " circle at 50 with open sights---nuff said--I'm ready to hunt

And get this--the plant i work at just called yesterday and asked if i would volunteer for an optional layoff--with FULL pay till the 1st of Jan.---woo-woo! Look out nannys--we have a liberal season here--i can take 3 bucks per season and 1 doe a day till Jan. 31

P.S.--Thanks for input and suggestions every one posted--For Bill T. to reply to something that seems now obviously user error says a lot about his faith in the bows---Mine is now restored

Thanks again--
