Magna porting

[waterfowler]

Can a shotgun barrell be magna ported? If it can, what is the outcome of this? My thinking is the gun will have a lot less kick, but the spread of the bbs will stay more compact. This would be fo bird hunting. Also, in a slug gun, would this improve accuarcy or not? Thanks

Money out of your pocket , that could have been spent on shells.

Magna ported a shotgun for less recoil , i.m.o. add some weight to your shotgun to reduce recoil .Added weight is a guaranteed way to reduce recoil.

I had a .375 H&H rifle Mag-Na-Ported, and it made quite a bit of difference - I'd estimate a 20% reduction in actual recoil and 50% reduction in muzzle jump.

As for shotguns . . . I've fired Pro-Ported shotguns and I can't tell the difference.

Think about it - the powder charge of a shotgun relative to the weight of the shot column is tiny compared to the powder charge of a high power rifle and a bullet, so the powder contributes little to shotgun recoil. Add in the pressure factor - CHAMBER pressure on a shotgun is comparable to MUZZLE pressure on a rifle - and by the time the shot charge passes the ports, there aren't enough powder gasses at a high enough pressure to make much difference by porting them upward.

Oh, I suppose theoretically there might be a little reduction in muzzle jump . . . but not enough for me to notice.

Shotgun Magnaport won't have an effect with target loads but will with full loads.

You might be better served by installing a recoil reducer, such as the Edwards Recoil Reducer.

Brownells lists all 3 models.
