Is there any substance to the concept that powder burn rate affects percieved recoil?

Thanks to all for your input, Brian

Yes there is proof that certain powders produce faster recoil. H4350 is notorious for being 'snappy' in lots of cartridges. Similar burn rate powders don't have the same characteristic in my experience.

Cheers.

It's very interesting. Thanks for the post. Brian

I recall in Shooting the Double Rifle, that certain powders at the same velocity recoiled more that others..I think they were comparing 4350s recoil to 4831, don't remember who won that race..

H4350 will have less recoil than H4831 at the same speed because it is faster and has less muzzle pressure.

I Find this " muzzle pressure/ burn rate " factor really interesting . It explains a lot to me. I am going experiment a bit.

Gerard, I have heard that faster twist make more recoil. Can you shed any light on that for us? Thanks, Brian

You could talk about the same issues with the .416 Rigby and Remington. Stock fit is more important to me than anything. I'd rather shoot a whole lot of my bigger bores than one 375 H&H, the only rifle that ever cut me.

Brian, I do not think it can be proven. An example would be a 223 with a 1:7" twist and one with a 1:14". One is double the twist of the other and recoil difference between the two cannot be measured. There are many examples and I once had a 7mm Rem Mag in the shop with a 1:10.5 twist. I shot the rifle extensively to figure why it would not group. Only when I measured the twist rate did I realise what it is. It felt just like any other 7mm Rem Mag.

Thanks Gerard. Good to know, Brian

I've owned the Ruger African 375 Ruger;and quite a few 375 H&H rifles. I found the Ruger African pretty lively but not unmanageable. My impression was that recoil was somewhat faster than the 375 H&H,likely due to the fact that the 375 Ruger takes sightly heavier powder charges and generates a bit more velocity.

Really though this is nitpicking. They are pretty similar.

I've owned a bunch of rifles chambered for many of the same cartridges but varying in twist rate. 300 win mags, 300 Weatherby, various 7 Rem Mags and even 375 H&H's with both 10" and 12" twist. I have a 10 twist Krueger ready to go on another 375 at present.

I have never seen any differences in recoil between the fast and slower twists.

I just talked to my son and he said the felt recoil has a component that none of the folks above directly recognized.
That component is the clothing worn by the shooter.
If you shoot in a hunting coat, the felt recoil will be markedly different than if you are at the range and shoot in only a shirt.

the Ruger round, being much shorter will have less recoil, as well as much higher velocity.

Don't take my word for it, just ask Hornady or Ruger...

What's the logic there?

what does "shorter" have to do with it?

Not me, I be too slow witted fer that class.

Mmmm....Having owned and shot both, I can't agree. Sales pitch IMO.

A shorter cartridge has nothing to do with recoil or recoil velocity. It's all about the weight of the rifle, amount of powder, bullet weight and bullet velocity F=MA simple physics. Perceived recoil is changed a lot by rifle stock design/fit and recoil pad

Agreed.

Another thing....Weight of the ejecta (powder charge)gets added into the recoil equation as well. The reason heavy charges of slow burning powders seem to kick "harder" than lighter charges of a faster powder.

absolutely

ok I get it You say one thing and mean the opposite..

that's one working definition of sarcasm...

It would be like Biebs sitting on the beach in Jersey next to a 400+ pound woman in a thong, and remembering what his Mother told him "If you can't think of something nice to say, don't say anything..."

When this woman says to him "my gosh it's hot today", the only thing he could think of to say, was "you really don't sweat much for a fat girl...".

Nice! lol
