After many hours tinkering with bareshafts and getting stiff results with full length Heritage 75s and 100 grain tips I started paying attention to the occasional smack the arrow gave my bow hand. My nock height was 9/16" to the bottom of the top nocking point and I had not previously noticed any fletching wear, but decided to move it up a bit. I set it at 23/32" and my stiff issues disappeared, but the bareshaft impacted, as expected several inches below the fletched shafts. I shot the nock off of one of my arrows and now I think I may be onto something...
Just to verify I shot a broadhead and it groups with the field points. I have heard that nock low is generally a bad thing, but that you can get a great tune with the nocking point set higher than dead even bareshaft tune. Anyhow at this point it seems to have made quite a difference. Having switched to 3 under several months ago I believe the bow is quieter with the higher nocking point as an added bonus. Am I on the right the right track?
Are you shooting an ILF bow? If not, your nock point is very low for 3 under on a bow tillered for split. I run 5/8" but 3/4 inch is not uncommon. Keep tinkering and you'll find that sweet spot where it all comes together.

Hi Mike. It is an rd longbow. It is at 23/32" (just under 3/4"). Much higher than the 9/16" that i had been using.
Sounds about right for 3 under. When I shot 3 under I had to raise the NP to around 3/4" to get decent arrow flight.
