I just did an arrow build and posted a 49 page Tutorial. It’s a few post down and explains how I like to tune my arrows.
*MY PERSONAL OPINION*- making your arrows as symmetrical as possible using a bare shaft and a fletched shaft tuning process with field points should,in my own theory, make your BH’s fly all the same and group together. Not necessarily with your field points. To me it’s more important to have a proper setup including the correct arrow spine matched with your bow, properly indexed arrows, as well as a consistent arrow setup/build. Bottom line a straight flying arrow will produce tight and consistent groups as well as getting the most kinetic energy upon impact of your target. This is why I choose a this process
1.paper tune with a bare shaft at 3-5 feet from the paper using a FP. For tail left and right I will yoke tune (add a twist, take out a twist, or a combination of both depending on cam lean @ full draw and axle to axle spec). For nock high/low I will adjust the rest on the vertical plane. Until I get a bullet hole with a bare shaft.
2. I will do the same thing with a fletched arrow at the same distance using a FP. I don’t touch the horizontal setting on my rest until the next few steps.
3. I will back up to 10-15 feet shooting the bare shaft first through paper. Usually the tail left/right tear will be close. To fix it I will MICRO ADJUST my rest with the horizontal movements this time (right/left). A little goes a long way! Tail high/low adjust with my rest on the vertical plane (up/down).Until a bullet hole is achieved.
4. Same process using fletched arrows with FP’s as number 3 process.
5. shoot both a fletched and bare shaft next to eachother. Should be shooting bullet holes. Now your bow string is symmetrically pushing the arrows straight (hypothetically).
6. I usually do walk back tuning(using FP’s). I put blue painters tape in a straight line down the middle of my target. Start at 20 yards using my 20 yard pin (Assuming you’re 20yard pin is sighted in) aiming at the top of the blue tape on my target. I’ll get a group (Should be on the blue tape if not re sight in your 20 yard pin) then move back to 50-60 yards aiming at the same spot with my same 20 yard pin. Shoot a group. The arrows will hit low but will tell you if you need to micro adjust your rest. If they hit right or left of the blue tape at the 50-60 yard mark then you need to adjust the rest until your 20 and 50-60 yard groups are in a straight vertical line, on the blue tape.
7. I’ll shoot my fletched arrow with a FP at 20 yards followed by a bare shaft. Depending where the bare shaft hits, either right or left of the fletched arrow, I’ll adjust my rest right or left to bring the fletched and bare shaft to 1/2” or less of each other. You can usually see if the bare shaft is indexing Tail right or left When you go pull your arrows out of the target.
8. After all that is accomplished I’ll sight in my BH’s *Adjusting my sight housing only* Because you already know the arrows are coming out of your bow square
