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!

Currently doing a load development on a .404 Jeffrey... it's always surprising to load .423 caliber bullets into a .404 caliber rifle. But we love it when we get 400 Gr North Fork SS bullets to 2300 FPS, those should hammer down on buffalo. Next up are the Cutting Edge solids and then Raptors... load 200 rounds of ammo for the customer and on to the next gun!
To much to political shit, to little Africa :-)
Spending a few years hunting out west then back to Africa!

Hello. If you haven't already sold this rifle then I will purchase. Please advise. Thank you.

I doubt you are interested in any trades but I was getting ready to list a Sauer 404 3 barrel set in the 10-12 price range if your interested. It has the 404J, 30-06 and 6.5 Creedmoor barrel. Only the 30-06 had been shot and it has 7 rounds through it as I was working on breaking the barrel in. It also has both the synthetic thumbhole stock and somewhere between grade 3-5 non thumbhole stock
