Does barrel length effect the felt recoil

does the barrel length of a (pump) shotgun effect the amount of recoil you feel?

it maybe just me but when i shoot with the 20" barrel on my 870 the recoil seem a lot more intense than when firing with my 26" barrel (firing same loads of coarse). is this just in my mind or is there actually a difference?:D
 
perhaps the longer one weighs more and soaks up alittle bit more of the recoil...
 
In general, as mentioned above, the longer barrel will weigh more, and also take more time to accelerate and rotate due to recoil.

Want a classic example? Try shooting an 8 3/8 inch S&W 629, then shoot the 2 1/2 inch barreled model with the same ammo.
 
It's funny I get less felt muzzle climb with my 3" 629 that I get with my 7.5" barrelled super blackhawk. I believe it's because I get less muzzle velocity with the 3 incher because the bullet leaves the barrel sooner therefore the impulse doesn't last as long. The difference in design may have something to do with it as well. I dont think its a factor with a shotgun so there more barrel mass and length may reduce recoil but with pistols it' s trickier. the nastiest recoiling gun in my collection is a davis derringer iin .32 ACP the little pr@@k bites the web of my hand and my palm i usually put it away after after 10 rounds.
 
Beside the weight... another factor for "perceived recoil" is the noise.
The 20" will be louder then the 26". If you do not beleive me, try this the next time you get a new shooter at the range, get them to fire a gun with only ear plugs... a little later on get them to fire that same gun/load combination with both ear plugs ans ear muff... They will most likely tell you that it waseasier the second around.

For some reason, women seem to be more affected by noise. When they tell you that they don't like the recoil of this or that gun, 9/10 the recoil problem will be taken care off with better earing protection.

just my 2 cents,
Mike.
 
yeah, i have noticed that when shooting the 20" there is a lot more noise.
so better hearing protection of myself, which intern will have my brain tell me that the recoil really aint that different between the barrels.:D
 
Another thing that may or may not be a factor in this case is the forcing cone. If the forcing cone is shorter in one barrel than the other (steeper angle), the recoil will be noticeably greater. If that's the case, it's not your imagination at all.

Given all other factors being equal, a short barrel will induce greater recoil because it emits a larger diameter "cloud" of ejecta gasses.

This phenomena has been documented and photographed.

Just another observation similar to this one....

If you are shooting hot loads out of a short barreled shotgun and produce a huge fireball, so to speak, it seems that this translates into more percieved recoil in some shooters. I have seen this a few time when comparing loads that are relatively similar or using the same load during the day vs dusk/dawn. I found this occured more in people less familiar to firearms and, in fact, could almost be reversed in more experienced or fun-loving shooters that focued more on the fireball and less on the recoil. Funny how our brain works... :D
