Fine Tuning Bowsight

[kidso]

Just wanted to comment on an interesting experience I have been having while sighting in my bow over the past six weeks to see if anyone else has gone through this.

 

I have excellent agreement between my field points and fixed broadheads from 20-80 yards and have been strictly shooting broadheads now by choice to better prepare myself for field conditions. Anyways, I have never shot more arrows with my bow in my life than I recently have over these past six weeks and I think this has actually been making my form improve and my releases smoother.

 

I think this is the case because I have found myself slightly adjusting the yardage markers on my adjustable slider sight from where I had set them, lets say two or three weeks ago. For example, The last two or three trips out to the range found me spending my shooting time at 70 and 80 yards and dialing in those yardages to extremely tight shooting arrow groups. Yesterday, I went back to 60 yards for the first time in three weeks and was shooting about three inches lower from where I had previously set my 60 yard tape mark.

 

I know that the 60 yard tape mark had not been moved or from its original location, so I feel that this "apparent movement" occurred as a result from my improving form and technique over time. Has anyone else experienced this? I found myself fine tuning my yardage mark at 50 yards as well, but they were not affected at yardages less than 50.

 

Anyways, I hope that is why a few yardage marks had slightly changed. My bow is new and it does have aftermarket strings on it and I have probably put about 600 shots through it. So I hope it is not some string or cable stretch that happened?

I get day to day very slight changes in impact from form as well. If you notice that you are constantly having to change your settings as well as the tune you might be having stretch issues. By slight day to day stuff is to be expected.

 

You can also take a sharpie or pencil and mark your cams where they intersect the limbs and create timing marks. If your setup changes (stretches) you will easily be able to determine it from the witness marks.

Thanks Elpepe. But, as a general rule, good quality strings and cables shouldn't stretch, correct? And I had also heard some rumorous talk about 500-1,000 shots to get your bow system "seated" into its specs, which I felt was an old wives tale.

I'd say the shooter will have more day to day variance than the bow.

Good strings are not "supposed" to stretch. Having said that, I have put on high quality strings, and I still shoot at least 250 shots before I set my peep. As stated above, the only way to keep string stretch under control is to mark your cams with a sharpie. I have done it on every bow I have owned.

I shoot winners choice and mine are "set" by 300 shots or less

Cable stretch is usually what happens before string stretch, my question is as you commented about shooting and adjusting your form. Have you even slightly adjusted your anchor points,? Any one of your anchor points being out of line will change everything as far as your distance grouping. Bring it into the shop and I'll gladly help you out. Archery HQ ask for Junior

Or maybe your anchor has changed slightly for that one day. If its just one day dont worry about it and the next your back on.

I agree with the guys above, I'd look at anchor point or possibly rest movement. You could be torquing your bow slightly different also, but that generally results in left to right impact changes. If you are still shooting great groups with broadheads, I wouldn't worry about it too much and maybe just adjust your site a bit to correct. Sounds like you're on a roll! Keep it up!

Well, shot my bow after a week off and everything was sighted in perfectly from last week. I am good up to 80 yards! Will wait one more week and re-check, and then I will finally apply transparent tape over my sight yardage marks to waterproof and protect them from the elements. Spring archery bear in two weeks!
