Recoil

[Walkalong]

A 165 can recoil less if the difference in velocity is enough, but that isn't the case here.

So ,I understand a lighter bullet using more powder would have more recoil but I am only using 4.4 for the 140 gr. , versus 4.7 for the 165 . Yes , potatohead I know rc ain't the only buckaroo on the site . I value all of the advice and discussion on THR. Thanks. Going fishing .

I hear you. Didnt mean to be rude, RC is definitely top notch. Just hoped you knew, and it sounds like you do, that there's a lot of good info here and a lot of these guys know their stuff, they could turn a nun into a handloader if she hung around long enough. And I definitely wasnt saying "listen to me, listen to me" because Im not on that level.

There could be some handloading nuns out there and that wasnt a good analogy but it's all I could come up with at the moment.

Well Chief without knowing the actual velocities this really becomes a tough nut to crack. I don't doubt for a moment that you feel what you feel. I also don't doubt the numbers and formula(s) would lie to us. We can beat this to death but never come to a resolution or explanation of things. Without those velocities we can only speculate on why you feel what you feel shooting those loads.

I have read Hatcher's notes on the subject of recoil as well as the SAAMI papers on the subject and numerous other white papers. While all are interesting they defy explaining why you feel what you feel for the recoils mentioned.

Think physics. The material a projectile is made from has nothing to do with its mass. Or it equal and opposite reaction.
A 165 will always have more recoil than a 140 due to its mass. Mind you, just having more powder will do that.

The material it's made of has nothing to do with mass. but it has to do with bullet hardness and coefficient of friction.

Part of the energy of the powder charge goes towards swaging the bullet into the rifling and overcoming friction. You can't ignore the difference. For instance, given the same powder charge, a 180 grain plated bullet will have more recoil than a 180 grain jacketed bullet. Because it will have a higher muzzle velocity. Same comparison between a cast bullet and a plated bullet, and the cast bullet will usually have the higher muzzle velocity and recoil.

I'm still curious, have you weighed the bullets yet? 180g bullets in the 140g box?
