Bore Diameter relative to Recoil in SAME WEIGHT bullets

[FEENIX]

Wow Thanks Feenix, Hugger

Interesting stuff fer sure!

I had no idea a powder change would effect recoil like that

Yes, partly due to the powder's burn rate property.

Just for $hz & j|||ۤ I run the recoil values on mine and my wife's rifles, as fired from the bench, anytime we build a new load.


I use ……https://shooterscalculator.com/ for the majority of my theoretical bullet drops, velocities, energies, ect @ distance as well as recoil values! memtb

Example for my rifle:

Thanks for responses guys

I found the type of powder/charge effecting recoil interesting

Cuz, the way I understand that, is; it means you could be putting up w more recoil than whats required to do the same job

When I say same job:
I'm referring to your rifle, with "certain" bullet at "certain" speed.
Different powders will produce different recoil amounts.
Very interesting stuff.

I usually look for a high load density and powder that's not what I call touchy = when you make a small adjustment in powder charge and see a drastic difference, in speed or pressure signs, I'm not a fan of that

91.0 grains of powder!

Jeeze that's a heavy amount

Big boy rifle....

I will soon experiment with Berger 250/300 and Chinchage 350 on my 338 Thor (NMI), requiring similar powder charges.

From experience. 338 ultra. 300 ultra. Twin rifles
180 projos.
Both 3500 fps mv.
The 300 has significantly more felt recoil.

And I'll add, the 300 has to be pushed harder to get that velo.

Now let's ask ourselves, if we had a 7 ultra rifle of the same specs, could it push a 180grn 3500?

Have you guys noticed more vibration on your cheek with some powder over others?

First, Thanks for info/contribution

I'd have to ask if you were to calculate volume of the 338 barrel, then the 300
The 300 would be less for same length, I wonder if you added length to 300 bbl of you would no longer have to push it so hard to equal velocities

Also surprised the 300 kicks MORE than the larger diameter
