New PSR III. Tunning problems - Javiglf

Hi, I´ve just received my new BW PSR III T/D 60" 60# @30". The bow is really nice, and great finished. But I have some problems tunning my arrows. I've used the bare shaft test, and my CE Heritage 350 has always flight weak, cutted to 31.5" and 100gr field points. I have problems of clearance too. When I've shot fletched arrows, hen feather strikes my hand. You can see the photos where the arrow is hitting the shelf and my hand.

Just testing. Tried to post reply to javiglf PSR tuning this morning...too many character? Now the subject heading is not shown other than re: I am just trying to find out if this post will take, and go to the appropriate Thread without the subject heading name. Or has there been a change so we can type in the subject heading in again, and make sure that no more than 32 character are used. Glad to hear you got the PSR propblem fixed.

I have finally tunned my bow and arrows. They fly pretty well with CE Heritage 350 31'5" 200gr point. The bow a brace height of 7". The problem is that I need a nock height of 1" to get a correct bare shaft flight, and I think it could be too much. I shoot 3 under, and the bow was oredered on that way.

javiglf, the following is just food for thought please do not take it out of text. In my opinion i do not think that your PSR is tuned yet. Ray's (my friend) PSR shoots bare shafts better than fletched arrows..i mean as perfect arrow flight as you can imagine. His nock set is 1/2" off square. When i 1st read your original post you did not give enough info for us to come up with an opinion on your problems. Your Heritage shafts at 31.5" lenght, does it still show weak shafts?, you mentioned 100gr field points. What was, or is the weight of the insert?...total weight up front of both 100gr field point and insert?. The reason i ask about the total weight up front is because Ray's PSR DID NOT LIKE anything but 125GR brass insert, and 125 field points. The brass inserts were glue-in broadhead adapters. We tuned his PSR using Taditional Only carbon shafts. His Brace height at final tune is 7" also. FYI,when we did try 75gr brass inserts with 125gr field points the feather quilt would rub his knuckle as well....ocassionally.......and not to mention that the bare shafts did not have any consistant arrow flight. At times they did fly well, and at times not worth a crap...not very forgiving. After final tuning just for kicks i asked Ray to pluck the string on purpose just to see how forgiving the bare shaft make up was of the Traditional Only Carbon shafts with 125 insert, and 125 field point. Even after plucking, the worst that would show would be just an ever so slight weak shaft. It was hard for Ray to pluck....he does have real good follow thru. Like i said javiglf...just food for thought. I have seen times where a 3/4" nock set was required but 1" sure seems high.

OOPS!, when i said that Ray's PSR DID NOT LIKE ANYTHING but 125gr inserts, and 125gr field points, i forgot to add to it. IT should have read: Ray's PSR, COMBINED WITH RAY'S SHOOTING TECHNIQUE... DID NOT LIKE anything but 125gr inserts, and 125 field points. A person's shooting technique (form), draw lenghts, griping bow, etc., always makes a difference in tuning our bows.

Thanks for your answer Gilbert. My problem at the begining was solved with the second nock on the string. After that, I was able to shot my bare shafts really straight with 125gr field point and 70gr insert. So at this moment there aren't any problems with the weakness of my arrows. Shooting this bare shafts, I need to rise my nock to 1" offsquare because the tail of the arrow was always down. But I think 1" is too high.

My 60 inch PSR is about the only bow I shoot; also had a 56 inch, but that was gifted to a friends son when he graduated from West Point. Both bows are tillered 3 under, and that's what I shoot. The nock is set to 15/16ths on both, I don't think your's is too high at all. If you're still worried about it, don't. Interesting that you've got such a low brace height, 7 1/2 works well (and quietly) for the 2 PSR's I've dealt with. Far as the feather bite, how are you gripping the bow? I've found that as long as I grip mine with a full hand on the bow longbow type grip, I don't have any problems. When I tinker with different grips, and get the heel of my palm off the bow, I'll run into feather problems.

What does Widow guys think about 1" offsquare nock? I watch some videos where Mr Beck always prefer an arrow tail down when bare shaft tunning because you could alwaysrise the nock. Thanks
