Pushing non-regulated PCP's too far

[PakProtector]

Given a critter hunting scenario, the drop between 40 and 60 yards is the most troublesome thing to deal with. It gets entertaining when the velocity vs pressure curve is added in, and so I try and minimize it.

Isn't there "something else going on" all the time?

Have no doubt that velocity varation does make a calculated difference....but not sure how important a difference between 1% and 3 or 4% in actual use  but we all like to chase perfection.

Wind shelter bench ranges at least remove the range estimations...shooting at one known distance removes scope adjustment changes and removes (almost) the wind changes.   But you still have the human at the trigger (which is a whole big pile of varation), pellet varation, barrel changes (tempetrue/fouling/etc.).

So I do tend to only really count the 4% shots....and if it's not too much of a penalty in shot count,  would limit it to 2%. 

Previous posts (a day or two back) about the M10/M11 and the energy differnce between slugs and pellets  got me to dig out an old M10 single shot and chronograph it though a few fills.

Ended up with a choice between 21-22 shots inside 4% or 15-16 shots inside 2%.  These are good 53.5 foot pound shots, good air efficiency, but not a whole lot of shots.

Guess the point of all this was that you can shoot non-regulated PCP's at a pretty good velocity varation....you just have to test to find where that "sweet spot" lives and limit your shooting to that area.

Robert,
Excellent write up! THANK YOU for taking the time to help educate the rest of us who want to learn more. I admit my head is spinning from the info, but certainly valuable and instructional.

HAPPY NEW YEAR and God bless!
