    Building arrows??

    To be fair the OP did ask about both FOC and weight: Also, I agree with @sclancy27. It's the weight itself (regardless of where on the arrow it's added) that's primarily responsible for a heavier arrow making a bow quieter. Increased FOC is simply a consequence of adding that weight to the...

    Arrow FOC

    I don't think he's a troll, just an engineer...we're not known for our charm or interpersonal skills:)

    Arrow FOC

    I often disagree with the Ashby crowd, but they do have some good info on the aerodynamics of arrow flight as explained by a former DoD ballistics engineer. It doesn't have all the answers, but it's a good start. https://www.ashbybowhunting.org/s/Barnette_Arrow-FLight-101.pdf

    Arrow FOC

    I'll reiterate my opinion that FOC is way less important than many folks claim and that there's no harm in completely ignoring it. That said, there is a plausible argument based on aerodynamic principles that higher FOC will improve an arrow's stability in flight. Positive aerodynamic...

    Arrow FOC

    If you want to simulate the additional rear weight of a lighted nock to see how they fly before you buy, glue a short piece of threaded rod inside an unlighted nock. Below is a weighted practice nock I made by supergluing a piece of 6-32 threaded steel rod inside a Bohning A Nock. 6-32 steel...

    Arrow FOC

    Interesting. Both of your arrows had the same total weight? Do you mind sharing the details of how each arrow was constructed (shaft make/model/spine/length, component weights)? I'm curious how great the difference in FOC was and what else you changed (besides insert weight) to keep TAW the same.

    Arrow FOC

    Are we talking weight or FOC? If we're talking weight, then, yes, a heavier arrow will drop faster and that drop will be more noticeable at longer ranges. But if we're talking FOC, I don't think FOC alone has a noticeable effect on trajectory. Two arrows of the same total weight but different...

    Arrow FOC

    What change occurs at 40 yds that makes FOC start having a dramatic effect?

    Arrow FOC

    My advice is to ignore FOC altogether. You're hitting where you aim and killing what you aim at...that's all that matters. Build your arrows for whatever speed/total weight you want and let FOC fall where it may.

    Building arrows??

    Don't worry about FOC. Build for your target total arrow weight and let FOC fall where it may. 450-500 gr is a good TAW for most hunters IMO. 3 vs. 4 vanes is largely a matter of personal preference. Either configuration can get the job done. The greater the surface area of your broadhead, the...

    New setup

    All bows have to be tuned to the shooter. Everyone grips the bow a little differently, anchors a little differently, etc. which affects how the arrow flies and what adjustments are needed to get broadheads hitting with field points. The first order of business is to achieve repeatable results...

    New setup

    Have you done any yoke tuning or rest tuning to try to shift broadhead POI to the right? It's a good idea to do a final check with broadheads, but most of your tuning can be done by shooting field point-tipped bareshafts, which are much easier on your targets.

    New setup

    To fix broadheads hitting left of field points, either shift your rest to the left or adjust your cam lean/spacing. Cam adjustment method varies by bow...some use shims to shift the cam left/right on the axle (Mathews, newer Hoyts), some use cable tension to torque the axle (older Hoyts &...

    Trad archery broadheads planing

    Good post. I love discussing the physics of archery. I would suggest one minor revision (that's mostly pedantic and doesn't really affect your broader point about tuning via brace height adjustment): peak draw weight and energy typically do change (slightly) when you alter brace height...

    Thawing, cutting, then Refreezing

    There's no need to "ventilate" the meat while it's in the cooler. Keep the valve/drain closed so the dry ice lasts longer.

    Thawing, cutting, then Refreezing

    I've kept whole quarters in the freezer for multiple weeks then thawed them out for final processing and have never noticed any degradation in meat quality. If freezer burn does occur, it's likely just on the surface that was going to get trimmed off anyway.

    Trad archery broadheads planing

    For a right-handed shooter, broadheads hitting right of field points indicates weak dynamic spine. Shortening the arrow, reducing front end weight, and switching to a stiffer static spine are ways to strengthen dynamic spine. Shifting the rest further away from the riser or building up the shelf...
