410 recoil vs 12g recoil

[rovercoupe]

I am sure its been done before but cannot find it so here we go,

 

I shot 19g through the 410 and theres virtually no recoil even with a light single barrel and then went over to the 12g and shot 21g and the recoil is really noticeable but only a 2g increase in weight so the question is why?

[sitsinhedges]

The shot is probably going much faster in the 12 gauge too which would create more recoil.

I thought that but had a look at the eley site and they claim the 12 is going about 200fps more than the 410 but my only thought might be that given the super slow fourlongs it could be that the trap is slow too but it seems to dust clays and my lead is the same as with the 12.

Main difference is 410 is 15gr or so of a slow burning powder to keep pressure down and achieve medium velocity , whilst 12g is 22 to 28 grains of fast burning powder to fill volume of bore and achieve high velocity

There is also the question of 'perceived' recoil by the shooter. Some people are more tolerant of recoil. I recently had a friend shoot my Yilditz o/u 410 with Fiocchi 3 inch 8s (19g) and he remarked how sharp the recoil was, when I don't even notice it. Unless the two cartridges are in a test facility to measure accurately then you will always have 'perceived' recoil by the shooter. Also you have the different gun, different shape, weight etc., to take into account and fit and shape of the stock can make a big difference to felt recoil. European shape rifle stocks with considerable drop to heel kick the doo doo out of me, hate 'em, but the straighter American style stocks in the same calibre, cartridge, and weight don't.

As Walker570 says gun fit helps.

 

On my rifles- Blaser in .300 I don't feel recoil or get much muzzle flip, but borrowing my friends .270wsm I thought it was dreadful.

Thanks gents that makes more sense, never thought about burn rate and stock fitment. I just took it as x amount of weight being thrown down a barrel should give the same result.
