Need help, Load discrepancy Swift vs Hodgdon

For OBT, here is the muzzle disturbance vs time with the sound wave impact. Note the
multiple reflections. Amplitudes are constant as he did not model any energy losses.

Mr. Long was going for ultimate accuracy and timed the bullet exit
at the flat portion of the curve, just before 1.25mSec with the idea being
that for small changes in barrel time, say between 1.2 and 1.26mSec, there
is no change in muzzle disturbance.

For me, since only interested in hunting, I time my bullet exit half way between
the muzzle disturbances, i.e. 1.1875mSec. Yes, with natural reload variations,
the bullet exit will encounter more or less disturbance, but in this area, it is almost
2 orders of magnitude less than if the bullet exits at the sound wave impact!
 
Burn out as many barrels as you can, I say…
Shooting is enjoyable, so it doesn’t matter if it’s chasing small groups at the range, developing multiple loads, shooting competitions or filling refrigerated trucks with venison. When the barrel is cooked, screw in another one and keep going.

Globally, most of the youngsters today couldn’t care less about hunting and shooting, so why leave them a safe queen in pristine condition with a hardly used barrel?
Lol
Shoot them if you got em and Enjoy it. Have fun!

Hey my friend, I am returning to SA for a Cape Buffalo hunt in June 26. My outfitter has suggested Highveld but I have read some poor reports. Wondering how satisfied you were with your mounts from them? Thanks in advance.
Finally back to somewhat normal I missed reading the messages and posts
